   Justice Stevens

delivered the opinion of the Court.

Petitioner Jose Padilla, a native of Honduras, has been a lawful permanent resident of the United States for more than 40 years. Padilla served this Nation with honor as a member of the U. S. Armed Forces during the Vietnam War. He now faces deportation after pleading guilty to the transportation of a large amount of marijuana in his tractor-trailer in the Commonwealth of Kentucky.

In this postconviction proceeding, Padilla claims that his counsel not only failed to advise him of this consequence prior to his entering the plea, but also told him that he “ 'did not have to worry about immigration status since he had been in the country so long’” 253 S. W. 3d 482, 483 (Ky. 2008). Padilla relied on his counsel’s erroneous advice when he pleaded guilty to the drug charges that made his deportation virtually mandatory. He alleges that he would have insisted on going to trial if he had not received incorrect advice from his attorney.

Assuming the truth of his allegations, the Supreme Court of Kentucky denied Padilla postconviction relief without the benefit of an evidentiary hearing. The court held that the Sixth Amendment’s guarantee of effective assistance of counsel does not protect a criminal defendant from erroneous advice about deportation because it is merely a “collateral” consequence of his conviction. Id., at 485. In its view, neither counsel’s failure to advise petitioner about the possibility of removal, nor counsel’s incorrect advice, could provide a basis for relief.

We granted certiorari, 555 U. S. 1169 (2009), to decide whether, as a matter of federal law, Padilla’s counsel had an obligation to advise him that the offense to which he was pleading guilty would result in his removal from this country. We agree with Padilla that constitutionally competent counsel would have advised him that his conviction for drug distribution made him subject to automatic deportation. Whether he is entitled to relief depends on whether he has been prejudiced, a matter that we do not address.

I

The landscape of federal immigration law has changed dramatically over the last 90 years. While once there was only a narrow class of deportable offenses and judges wielded broad discretionary authority to prevent deportation, immigration reforms over time have expanded the class of deport-able offenses and limited the authority of judges to alleviate the harsh consequences of deportation. The “drastic measure” of deportation or removal, Fong Haw Tan v. Phelan, 333 U. S. 6, 10 (1948), is now virtually inevitable for a vast number of noncitizens convicted of crimes.

The Nation’s first 100 years was “a period of unimpeded immigration.” C. Gordon & H. Rosenfield, Immigration Law and Procedure §1.2a, p. 5 (1959). An early effort to empower the President to order the deportation of those immigrants he “judge[d] dangerous to the peace and safety of the United States,” Act of June 25, 1798, ch. 58, 1 Stat. 571, was short lived and unpopular. Gordon § 1.2, at 5. It was not until 1875 that Congress first passed a statute barring convicts and prostitutes from entering the country, Act of Mar. 3, 1875, ch. 141, 18 Stat. 477. Gordon § 1.2b, at 6. In 1891, Congress added to the list of excludable persons those “who have been convicted of a felony or other infamous crime or misdemeanor involving moral turpitude.” Act of Mar. 3,1891, ch. 551, 26 Stat. 1084.

The Immigration Act of 1917 (1917 Act) brought “radical changes” to our law. S. Rep. No. 1515, 81st Cong, 2d Sess., 54-55 (1950). For the first time in our history, Congress made classes of noncitizens deportable based on conduct committed on American soil. Id., at 55. Section 19 of the 1917 Act authorized the deportation of “any alien who is hereafter sentenced to imprisonment for a term of one year or more because of conviction in this country of a crime involving moral turpitude, committed within five years after the entry of the alien to the United States . . ..” 39 Stat. 889. And §19 also rendered deportable noncitizen recidivists who commit two or more crimes of moral turpitude at any time after entry. Ibid. Congress did not, however, define the term “moral turpitude.”

While the 1917 Act was “radical” because it authorized deportation as a consequence of certain convictions, the Act also included a critically important procedural protection to minimize the risk of unjust deportation: At the time of sentencing or within 30 days thereafter, the sentencing judge in both state and federal prosecutions had the power to make a recommendation “that such alien shall not be deported.” Id., at 890. This procedure, known as a judicial recommendation against deportation, or JRAD, had the effect of binding the Executive to prevent deportation; the statute was “consistently .. . interpreted as giving the sentencing judge conclusive authority to decide whether a particular conviction should be disregarded as a basis for deportation,” Janvier v. United States, 793 F. 2d 449, 452 (CA2 1986). Thus, from 1917 forward, there was no such creature as an automatically deportable offense. Even as the class of'deport-able offenses expanded, judges retained discretion to ameliorate unjust results on a case-by-case basis.

Although narcotics offenses — such as the offense at issue in this case — provided a distinct basis for deportation as early as 1922, the JRAD procedure was generally available to avoid deportation in narcotics convictions. See United States v. O’Rourke, 213 F. 2d 759, 762 (CA8 1954). Except for “technical, inadvertent and insignificant violations of the laws relating to narcotics,” ibid., it appears that courts treated narcotics offenses as crimes involving moral turpitude for purposes of the 1917 Act’s broad JRAD provision. See ibid, (recognizing that until 1952 a JRAD in a narcotics case “was effective to prevent deportation” (citing Dang Nam v. Bryan, 74 F. 2d 379, 380-381 (CA9 1934))).

In light of both the steady expansion of deportable offenses and the significant ameliorative effect of a JRAD, it is unsurprising that, in the wake of Strickland v. Washington, 466 U. S. 668 (1984), the Second Circuit held that the Sixth Amendment right to effective assistance of counsel applies to a JRAD request or lack thereof, see Janvier, 793 F. 2d 449. See also United States v. Castro, 26 F. 3d 557 (CA5 1994). In its view, seeking a JRAD was “part of the sentencing” process, Janvier, 793 F. 2d, at 452, even if deportation itself is a civil action. Under the Second Circuit’s reasoning, the impact of a conviction on a noncitizen’s ability to remain in the country was a central issue to be resolved during the sentencing process — not merely a collateral matter outside the scope of counsel’s duty to provide effective representation.

However, the JRAD procedure is no longer part of our law. Congress first circumscribed the JRAD provision in the 1952 Immigration and Nationality Act (INA), and in 1990 Congress entirely eliminated it, 104 Stat. 5050. In 1996, Congress also eliminated the Attorney General’s authority to grant discretionary relief from deportation, 110 Stat. 3009-596, an authority that had been exercised to prevent the deportation of over 10,000 noncitizens during the 5-year period prior to 1996, INS v. St. Cyr, 533 U. S. 289, 296 (2001). Under contemporary law, if a noncitizen has committed a removable offense after the 1996 effective date of these amendments, his removal is practically inevitable but for the possible exercise of limited remnants of equitable discretion vested in the Attorney General to cancel removal for non-citizens convicted of particular classes of offenses. See 8 U. S. C. § 1229b. Subject to limited exceptions, this discretionary relief is not available for an offense related to trafficking in a controlled substance. See § 1101 (a)(43)(B); § 1228.

These changes to our immigration law have dramatically raised the stakes of a noncitizen’s criminal conviction. The importance of accurate legal advice for noncitizens accused of crimes has never been more important. These changes confirm our view that, as a matter of federal law, deportation is an integral part — indeed, sometimes the most important part — of the penalty that may be imposed on noncitizen defendants who plead guilty to specified crimes.

II

Before deciding whether to plead guilty, a defendant is entitled to “the effective assistance of competent counsel.” McMann v. Richardson, 397 U. S. 759, 771 (1970); Strickland, 466 U. S., at 686. The Supreme Court of Kentucky rejected Padilla’s ineffectiveness claim on the ground that the advice he sought about the risk of deportation concerned only collateral matters, i. e., those matters not within the sentencing authority of the state trial court. 253 S. W. 3d, at 483-484 (citing Commonwealth v. Fuartado, 170 S. W. 3d 384 (2005)). In its view, “collateral consequences are outside the scope of representation required by the Sixth Amendment,” and, therefore, the “failure of defense counsel to advise the defendant of possible deportation consequences is not cognizable as a claim for ineffective assistance of counsel.” 253 S. W. 3d, at 483. The Kentucky high court is far from alone in this view.

We, however, have never applied a distinction between direct and collateral consequences to define the scope of constitutionally “reasonable professional assistance” required under Strickland, 466 U. S., at 689. Whether that distinction is appropriate is a question we need not consider in this case because of the unique nature of deportation.

We have long recognized that deportation is a particularly severe “penalty,” Fong Yue Ting v. United States, 149 U. S. 698, 740 (1893); but it is not, in a strict sense, a criminal sanction. Although removal proceedings are civil in nature, see INS v. Lopez-Mendoza, 468 U. S. 1032, 1038 (1984), deportation is nevertheless intimately related to the criminal process. Our law has enmeshed criminal convictions and the penalty of deportation for nearly a century, see Part I, supra, at 360-364. And, importantly, recent changes in our immigration law have made removal nearly an automatic result for a broad class of noncitizen offenders. Thus, we find it “most difficult” to divorce the penalty from the conviction in the deportation context. United States v. Russell, 686 F. 2d 35, 38 (CADC 1982). Moreover, we are quite confident that noncitizen defendants facing a risk of deportation for a particular offense find it even more difficult. See St Cyr, 533 U. S., at 322 (“There can be little doubt that, as a general matter, alien defendants considering whether to enter into a plea agreement are acutely aware of the immigration consequences of their convictions”).

Deportation as a consequence of a criminal conviction is, because of its close connection to the criminal process, uniquely difficult to classify as either a direct or a collateral consequence. The collateral versus direct distinction is thus ill suited to evaluating a Strickland claim concerning the specific risk of deportation. We conclude that advice regarding deportation is not categorically removed from the ambit of the Sixth Amendment right to counsel. Strickland applies to Padilla’s claim.

III

Under Strickland, we first determine whether counsel’s representation “fell below an objective standard of reasonableness.” 466 U. S., at 688. Then we ask whether “there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id., at 694. The first prong — constitutional deficiency — is necessarily linked to the practice and expectations of the legal community: “The proper measure of attorney performance remains simply reasonableness under prevailing professional norms.” Id., at 688. We long have recognized that “[prevailing norms of practice as reflected in American Bar Association standards and the like . .. are guides to determining what is reasonable . . . .” Ibid.; Bobby v. Van Hook, 558 U. S. 4, 7 (2009) (per curiam); Florida v. Nixon, 543 U. S. 175, 191, and n. 6 (2004); Wiggins v. Smith, 539 U. S. 510, 524 (2003); Williams v. Taylor, 529 U. S. 362, 396 (2000). Although they are “only guides,” Strickland, 466 U. S., at 688, and not “inexorable commands,” Bobby, 558 U. S., at 8, these standards may be valuable measures of the prevailing professional norms of effective representation, especially as these standards have been adapted to deal with the intersection of modern criminal prosecutions and immigration law.

The weight of prevailing professional norms supports the view that counsel must advise her client regarding the risk of deportation. National Legal Aid and Defender Assn., Performance Guidelines for Criminal Defense Representation § 6.2 (1995); G. Herman, Plea Bargaining § 3.03, pp. 20-21 (1997); Chin & Holmes, Effective Assistance of Counsel and the Consequences of Guilty Pleas, 87 Cornell L. Rev. 697, 713-718 (2002); A. Campbell, Law of Sentencing §13:23, pp. 555, 560 (3d ed. 2004); Dept. of Justice, Office of Justice Programs, 2 Compendium of Standards for Indigent Defense Systems, Standards for Attorney Performance, pp. DIO, H8-H9, J8 (2000) (providing survey of guidelines across multiple jurisdictions); ABA Standards for Criminal Justice, Prosecution Function and Defense Function 4-5.1(a), p. 197 (3d ed. 1993); ABA Standards for Criminal Justice, Pleas of Guilty 14-3.2(f), p. 116 (3d ed. 1999). “ [Authorities of every stripe — including the American Bar Association, criminal defense and public defender organizations, authoritative treatises, and state and city bar publications — universally require defense attorneys to advise as to the risk of deportation consequences for non-citizen clients . . . .” Brief for Legal Ethics, Criminal Procedure, and Criminal Law Professors as Amici Curiae 12-14 (footnotes omitted) (citing, inter alia, National Legal Aid and Defender Assn., Performance Guidelines for Criminal Prosecution §§6.2-6.4 (1997); S. Bratton & E. Kelley, Practice Points: Representing a Non-citizen in a Criminal Case, 31 The Champion 61 (Jan./Feb. 2007); N. Tooby, Criminal Defense of Immigrants § 1.3 (3d ed. 2003); 2 Criminal Practice Manual §§45:3,45:15 (West 2009)).

We too have previously recognized that “ ‘[preserving the client’s right to remain in the United States may be more important to the client than any potential jail sentence.’” St. Cyr, 533 U. S., at 322 (quoting 3 Bender, Criminal Defense Techniques §§60A.01, 60A.02[2] (1999)). Likewise, we have recognized that “preserving the possibility of” discretionary relief from deportation under § 212(c) of the 1952 INA, 66 Stat. 187, repealed by Congress in 1996, “would have been one of the principal benefits sought by defendants deciding whether to accept a plea offer or instead to proceed to trial.” St. Cyr, 533 U. S., at 323. We expected that counsel who were unaware of the discretionary relief measures would “follofw] the advice of numerous practice guides” to advise themselves of the importance of this particular form of discretionary relief. Ibid., n. 50.

In the instant case, the terms of the relevant immigration statute are succinct, clear, and explicit in defining the removal consequence for Padilla’s conviction. See 8 U. S. C. § 1227(a)(2)(B)(i) (“Any alien who at any time after admission has been convicted of a violation of (or a conspiracy or attempt to violate) any law or regulation of a State, the United States, or a foreign country relating to a controlled substance . . . , other than a single offense involving possession for one’s own use of 30 grams or less of marijuana, is deportable”). Padilla’s counsel could have easily determined that his plea would make him eligible for deportation simply from reading the text of the statute, which addresses not some broad classification of crimes but specifically commands removal for all controlled substances convictions except for the most trivial of marijuana possession offenses. Instead, Padilla’s counsel provided him false assurance that his conviction would not result in his removal from this country. This is not a hard case in which to find deficiency: The consequences of Padilla’s plea could easily be determined from reading the removal statute, his deportation was presumptively mandatory, and his counsel’s advice was incorrect.

Immigration law can be complex, and it is a legal specialty of its own. Some members of the bar who represent clients facing criminal charges, in either state or federal court or both, may not be well versed in it. There will, therefore, undoubtedly be numerous situations in which the deportation consequences of a particular plea are unclear or uncertain. The duty of the private practitioner in such cases is more limited. When the law is not succinct and straightforward (as it is in many of the scenarios posited by Justice Alito), a criminal defense attorney need do no more than advise a noncitizen client that pending criminal charges may carry a risk of adverse immigration consequences. But when the deportation consequence is truly clear, as it was in this case, the duty to give correct advice is equally clear.

Accepting his allegations as true, Padilla has sufficiently alleged constitutional deficiency to satisfy the first prong of Strickland. Whether Padilla is entitled to relief on his claim will depend on whether he can satisfy Strickland’s second prong, prejudice, a matter we leave to the Kentucky courts to consider in the first instance.

IV

The Solicitor General has urged us to conclude that Strickland applies to Padilla’s claim only to the extent that he has alleged affirmative misadvice. In the United States’ view, “counsel is not constitutionally required to provide advice on matters that will not be decided in the criminal case . . . ,” though counsel is required to provide accurate advice if she chooses to discuss these matters. Brief for United States as Amicus Curiae 10.

Respondent and Padilla both find the Solicitor General’s proposed rule unpersuasive, although it has support among the lower courts. See, e. g., United States v. Couto, 311 F. 3d 179, 188 (CA2 2002); United States v. Kwan, 407 F. 3d 1005 (CA9 2005); Sparks v. Sowders, 852 F. 2d 882 (CA6 1988); United States v. Russell, 686 F. 2d 35 (CADC 1982); State v. Rojas-Martinez, 2005 UT 86, 125 P. 3d 930, 935; In re Resendiz, 25 Cal. 4th 230, 19 P. 3d 1171 (2001). Kentucky describes these decisions isolating an affirmative misadvice claim as “result-driven, incestuous . . . [, and] completely lacking in legal or rational bases.” Brief for Respondent 31. We do not share that view, but we agree that there is no relevant difference “between an act of commission and an act of omission” in this context. Id., at 30; Strickland, 466 U. S., at 690 (“The court must then determine whether, in light of all the circumstances, the identified acts or omissions were outside the wide range of professionally competent assistance”); see also State v. Paredez, 2004-NMSC-036, 136 N. M. 533, 538-539.

A holding limited to affirmative misadvice would invite two absurd results. First, it would give counsel an incentive to remain silent on matters of great importance, even when answers are readily available. Silence under these circumstances would be fundamentally at odds with the critical obligation of counsel to advise the client of “the advantages and disadvantages of a plea agreement.” Libretti v. United States, 516 U. S. 29, 50-51 (1995). When attorneys know that their clients face possible exile from this country and separation from their families, they should not be encouraged to say nothing at all. Second, it would deny a class of clients least able to represent themselves the most rudimentary advice on deportation even when it is readily available. It is quintessentially the duty of counsel to provide her client with available advice about an issue like deportation, and the failure to do so “clearly satisfies the first prong of the Strickland analysis.” Hill v. Lockhart, 474 U. S. 52, 62 (1985) (White, J., concurring in judgment).

We have given serious consideration to the concerns that the Solicitor General, respondent, and amici have stressed regarding the importance of protecting the finality of convictions obtained through guilty pleas. We confronted a similar “floodgates” concern in Hill, see id., at 58, but nevertheless applied Strickland to a claim that counsel had failed to advise the client regarding his parole eligibility before he pleaded guilty.

A flood did not follow in that decision’s wake. Surmounting Strickland’s high bar is never an easy task. See, e. g., 466 U. S., at 689 (“Judicial scrutiny of counsel’s performance must be highly deferential”); id., at 693 (observing that “[a]ttorney errors ... are as likely to be utterly harmless in a particular case as they are to be prejudicial”). Moreover, to obtain relief on this type of claim, a petitioner must convince the court that a decision to reject the plea bargain would have been rational under the circumstances. See Roe v. Flores-Ortega, 528 U. S. 470, 480, 486 (2000). There is no reason to doubt that lower courts — now quite experienced with applying Strickland — can effectively and efficiently use its framework to separate specious claims from those with substantial merit.

It seems unlikely that our decision today will have a significant effect on those convictions already obtained as the result of plea bargains. For at least the past 15 years, professional norms have generally imposed an obligation on counsel to provide advice on the deportation consequences of a client’s plea. See supra, at 368-371. We should, therefore, presume that counsel satisfied their obligation to render competent advice at the time their clients considered pleading guilty. Strickland, 466 U. S., at 689.

Likewise, although we must be especially careful about recognizing new grounds for attacking the validity of guilty pleas, in the 25 years since we first applied Strickland to claims of ineffective assistance at the plea stage, practice has shown that pleas are less frequently the subject of collateral challenges than convictions obtained after a trial. Pleas account for nearly 95% of all criminal convictions. But they account for only approximately 30% of the habeas petitions filed. The nature of relief secured by a successful collateral challenge to a guilty plea — an opportunity to withdraw the plea and proceed to trial — imposes its own significant limiting principle: Those who collaterally attack their guilty pleas lose the benefit of the bargain obtained as a result of the plea. Thus, a different calculus informs whether it is wise to challenge a guilty plea in a habeas proceeding because, ultimately, the challenge may result in a less favorable outcome for the defendant, whereas a collateral challenge to a conviction obtained after a jury trial has no similar downside potential.

Finally, informed consideration of possible deportation can only benefit both the State and noncitizen defendants during the plea-bargaining process. By bringing deportation consequences into this process, the defense and prosecution may well be able to reach agreements that better satisfy the interests of both parties. As in this case, a criminal episode may provide the basis for multiple charges, of which only a subset mandate deportation following conviction. Counsel who possess the most rudimentary understanding of the deportation, consequences of a particular criminal offense may be able to plea bargain creatively with the prosecutor in order to craft a conviction and sentence that reduce the likelihood of deportation, as by avoiding a conviction for an offense that automatically triggers the removal consequence. At the same time, the threat of deportation may provide the defendant with a powerful incentive to plead guilty to an offense that does not mandate that penalty in exchange for a dismissal of a charge that does.

In sum, we have long recognized that the negotiation of a plea bargain is a critical phase of litigation for purposes of the Sixth Amendment right to effective assistance of counsel. Hill, 474 U. S., at 57; see also Richardson, 397 U. S., at 770-771. The severity of deportation — “the equivalent of banishment or exile,” Delgadillo v. Carmichael, 332 U. S. 388, 390-391 (1947) — only underscores how critical it is for counsel to inform her noncitizen client that he faces a risk of deportation.

V

It is our responsibility under the Constitution to ensure that no criminal defendant — whether a citizen or not — is left to the “mercies of incompetent counsel.” Richardson, 397 U. S., at 771. To satisfy this responsibility, we now hold that counsel must inform her client whether his plea carries a risk of deportation. Our longstanding Sixth Amendment precedents, the seriousness of deportation as a consequence of a criminal plea, and the concomitant impact of deportation on families living lawfully in this country demand no less.

Taking as true the basis for his motion for postconviction relief, we have little difficulty concluding that Padilla has sufficiently alleged that his counsel was constitutionally deficient. Whether Padilla is entitled to relief will depend on whether he can demonstrate prejudice as a result thereof, a question we do not reach because it was not passed on below. See Verizon Communications Inc. v. FCC, 535 U. S. 467, 530 (2002).

The judgment of the Supreme Court of Kentucky is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.

It is so ordered.

Justice Alito,

with whom The Chief Justice joins, concurring in the judgment.

I concur in the judgment because a criminal defense attorney fails to provide effective assistance within the meaning of Strickland v. Washington, 466 U. S. 668 (1984), if the attorney misleads a noncitizen client regarding the removal consequences of a conviction. In my view, such an attorney must (1) refrain from unreasonably providing incorrect advice and (2) advise the defendant that a criminal conviction may have adverse immigration consequences and that, if the alien wants adviee on this issue, the alien should consult an immigration attorney. I do not agree with the Court that the attorney must attempt to explain what those consequences may be. As the Court concedes, “[immigration law can be complex”; “it is a legal specialty of its own”; and “[s]ome members of the bar who represent clients facing criminal charges, in either state or federal court or both, may not be well versed in it.” Ante, at 369. The Court nevertheless holds that a criminal defense attorney must provide advice in this specialized area in those cases in which the law is “succinct and straightforward” — but not, perhaps, in other situations. Ibid. This vague, halfway test will lead to much confusion and needless litigation.

I

Under Strickland, an attorney provides ineffective assistance if the attorney’s representation does not meet reasonable professional standards. 466 U. S., at 688. Until today, the longstanding and unanimous position of the federal courts was that reasonable defense counsel generally need only advise a client about the direct consequences of a criminal conviction. See, e. g., United States v. Gonzalez, 202 F. 3d 20, 28 (CA1 2000) (ineffective-assistance-of-counsel claim fails if “based on an attorney’s failure to advise a client of his plea’s immigration consequences”); United States v. Banda, 1 F. 3d 354, 355 (CA5 1993) (holding that “an attorney’s failure to advise a client that deportation is a possible consequence of a guilty plea does not constitute ineffective assistance of counsel”); see generally Chin & Holmes, Effective Assistance of Counsel and the Consequences of Guilty Pleas, 87 Cornell L. Rev. 697, 699 (2002) (hereinafter Chin & Holmes) (noting that “virtually all jurisdictions” — including “eleven federal circuits, more than thirty states, and the District of Columbia” — “hold that defense counsel need not discuss with their clients the collateral consequences of a conviction,” including deportation). While the line between “direct” and “collateral” consequences is not always clear, see ante, at 364, n. 8, the collateral-consequences rule expresses an important truth: Criminal defense attorneys have expertise regarding the conduct of criminal proceedings. They are not expected to possess — and very often do not possess — expertise in other areas of the law, and it is unrealistic to expect them to provide expert advice on matters that lie outside their area of training and experience.

This case happens to involve removal, but criminal convictions can carry a wide variety of consequences other than conviction and sentencing, including civil commitment, civil forfeiture, the loss of the right to vote, disqualification from public benefits, ineligibility to possess firearms, dishonorable discharge from the Armed Forces, and loss of business or professional licenses. Chin & Holmes 705-706. A criminal conviction may also severely damage a defendant’s reputation and thus impair the defendant’s ability to obtain future employment or business opportunities. All of those consequences are “seriou[s],” see ante, at 374, but this Court has never held that a criminal defense attorney’s Sixth Amendment duties extend to providing advice about such matters.

The Court tries to justify its dramatic departure from precedent by pointing to the views of various professional organizations. See ante, at 367 (“The weight of prevailing professional norms supports the view that counsel must advise her client regarding the risk of deportation”). However, ascertaining the level of professional competence required by the Sixth Amendment is ultimately a task for the courts. E. g., Roe v. Flores-Ortega, 528 U. S. 470, 477 (2000). Although we may appropriately consult standards promulgated by private bar groups, we cannot delegate to these groups our task of determining what the Constitution commands. See Strickland, supra, at 688 (explaining that “[prevailing norms of practice as reflected in American Bar Association standards ... are guides to determining what is reasonable, but they are only guides”). And we must recognize that such standards may represent only the aspirations of a bar group rather than an empirical assessment of actual practice.

Even if the only relevant consideration were “prevailing professional norms,” it is hard to see how those norms can support the duty the Court today imposes on defense counsel. Because many criminal defense attorneys have little understanding of immigration law, see ante, at 369, it should follow that a criminal defense attorney who refrains from providing immigration advice does not violate prevailing professional norms. But the Court’s opinion would not just require defense counsel to warn the client of a general risk of removal; it would also require counsel, in at least some cases, to specify what the removal consequences of a conviction would be. See ante, at 368-369.

The Court’s new approach is particularly problematic because providing advice on whether a conviction for a particular offense will make an alien removable is often quite complex. “Most crimes affecting immigration status are not specifically mentioned by the [Immigration and Nationality Act (INA)], but instead fall under a broad category of crimes, such as crimes involving moral turpitude or aggravated felonies.” M. Garcia & L. Eig, CRS Report for Congress, Immigration Consequences of Criminal Activity (Sept. 20,2006) (summary) (emphasis in original). As has been widely acknowledged, determining whether a particular crime is an “aggravated felony” or a “crime involving moral turpitude [(CIMT)]” is not an easy task. See R. McWhirter, ABA, The Criminal Lawyer’s Guide to Immigration Law: Questions and Answers 128 (2d ed. 2006) (hereinafter ABA Guidebook) (“Because of the increased complexity of aggravated felony law, this edition devotes a new [30-page] chapter to the subject”); id., §5.2, at 146 (stating that the aggravated felony list at 8 U. S. C. § 1101(a)(43) is not clear with respect to several of the listed categories, that “the term ‘aggravated felonies’ can include misdemeanors,” and that the determination of whether a crime is an “aggravated felony” is made “even more difficult” because “several agencies and courts interpret the statute,” including Immigration and Customs Enforcement, the Board of Immigration Appeals (BIA), and Federal Circuit and District Courts considering immigration-law and criminal-law issues); ABA Guidebook §4.65, at 130 (“Because nothing is ever simple with immigration law, the terms ‘conviction,’ ‘moral turpitude,’ and ‘single scheme of criminal misconduct’ are terms of art”); id., §4.67, at 130 (“[T]he term ‘moral turpitude’ evades precise definition”).

Defense counsel who consults a guidebook on whether a particular crime is an “aggravated felony” will often find that the answer is not “easily ascertained.” For example, the ABA Guidebook answers the question “Does simple possession count as an aggravated felony?” as follows: “Yes, at least in the Ninth Circuit.” Id., §5.35, at 160 (emphasis added). After a dizzying paragraph that attempts to explain the evolution of the Ninth Circuit’s view, the ABA Guidebook continues: “Adding to the confusion, however, is that the Ninth Circuit has conflicting opinions depending on the context on whether simple drug possession constitutes an aggravated felony under 8 U. S. C. § 1101(a)(43).” Id., § 5.35, at 161 (citing cases distinguishing between whether a simple possession offense is an aggravated felony “for immigration purposes” or for “sentencing purposes”). The ABA Guidebook then proceeds to explain that “attempted possession,” id., § 5.36, at 161 (emphasis added), of a controlled substance is an aggravated felony, while “[c]onviction under the federal accessory after the fact statute is probably not an aggravated felony, but a conviction for accessory after the fact to the manufacture of methamphetamine is an aggravated felony,” id., §5.37, at 161 (emphasis added). Conspiracy or attempt to commit drug trafficking are aggravated felonies, but “[s]olieitation is not a drug-trafficking offense because a generic solicitation offense is not an offense related to a controlled substance and therefore not an aggravated felony.” Id., §5.41, at 162.

Determining whether a particular crime is one involving moral turpitude is no easier. See id., at 134 (“Writing bad checks may or may not be a CIMT” (emphasis added)); ibid. (“[RJeckless assault coupled with an element of injury, but not serious injury, is probably not a CIMT” (emphasis added)); id., at 135 (misdemeanor driving under the influence is generally not a CIMT, but may be a CIMT if the DUI results in injury or if the driver knew that his license had been suspended or revoked); id., at 136 (“If there is no element of actual injury, the endangerment offense may not be a CIMT” (emphasis added)); ibid. (‘Whether [a child abuse] conviction involves moral turpitude may depend on the subsection under which the individual is convicted. Child abuse done with criminal negligence probably is not a CIMT” (emphasis added)).

Many other terms of the INA are similarly ambiguous or may be confusing to practitioners not versed in the intricacies of immigration law. To take just a few examples, it may be hard, in some cases, for defense counsel even to determine whether a client is an alien, or whether a particular state disposition will result in a “conviction” for purposes of federal immigration law. The task of offering advice about the immigration consequences of a criminal conviction is further complicated by other problems, including significant variations among Circuit interpretations of federal immigration statutes; the frequency with which immigration law changes; different rules governing the immigration consequences of juvenile, first-offender, and foreign convictions; and the relationship between the “length and type of sentence” and the determination “whether [an alien] is subject to removal, eligible for relief from removal, or qualified to become a naturalized citizen,” Immigration Law and Crimes §2:1, at 2-2 to 2-3.

In short, the professional organizations and guidebooks on which the Court so heavily relies are right to say that “nothing is ever simple with immigration law” — including the determination whether immigration law clearly makes a particular offense removable. ABA Guidebook §4.65, at 130; Immigration Law and Crimes §2:1. I therefore cannot agree with the Court’s apparent view that the Sixth Amendment requires criminal defense attorneys to provide immigration advice.

The Court tries to downplay the severity of the burden it imposes on defense counsel by suggesting that the scope of counsel’s duty to offer advice concerning deportation consequences may turn on how hard it is to determine those consequences. Where “the terms of the relevant immigration statute are succinct, clear, and explicit in defining the removal consequence[s]” of a conviction, the Court says, counsel has an affirmative duty to advise the client that he will be subject to deportation as a result of the plea. Ante, at 368. But “[w]hen the law is not succinct and straightforward ..., a criminal defense attorney need do no more than advise a noncitizen client that pending criminal charges may carry a risk of adverse immigration consequences.” Ante, at 369. This approach is problematic for at least four reasons.

First, it will not always be easy to tell whether a particular statutory provision is “succinct, clear, and explicit.” How can an attorney who lacks general immigration-law expertise be sure that a seemingly clear statutory provision actually means what it seems to say when read in isolation? What if the application of the provision to a particular case is not clear but a cursory examination of case law or administrative decisions would provide a definitive answer? See Immigration Law and Crimes §2:1, at 2-2 (“Unfortunately, a practitioner or respondent cannot tell easily whether a conviction is for a removable offense.... [T]he cautious practitioner or apprehensive respondent will not know conclusively the future immigration consequences of a guilty plea”).

Second, if defense counsel must provide advice regarding only one of the many collateral consequences of a criminal conviction, many defendants are likely to be misled. To take just one example, a conviction for a particular offense may render an alien excludable but not removable. If an alien charged with such an offense is advised only that pleading guilty to such an offense will not result in removal, the alien may be induced to enter a guilty plea without realizing that a consequence of the plea is that the alien will be unable to reenter the United States if the alien returns to his or her home country for any reason, such as to visit an elderly parent or to attend a funeral. See ABA Guidebook § 4.14, at 111 (“Often the alien is both excludable and removable. At times, however, the lists are different. Thus, the oddity of an alien that is inadmissible but not deportable. This alien should not leave the United States because the government will not let him back in” (emphasis in original)). Incomplete legal advice may be worse than no advice at all because it may mislead and may dissuade the client from seeking advice from a more knowledgeable source.

Third, the Court’s rigid constitutional rule could inadvertently head off more promising ways of addressing the underlying problem — such as statutory or administrative reforms requiring trial judges to inform a defendant on the record that a guilty plea may carry adverse immigration consequences. As amici point out, “28 states and the District of Columbia have already adopted rules, plea forms, or statutes requiring courts to advise criminal defendants of the possible immigration consequences of their pleas.” Brief for State of Louisiana et al. 25; accord, Chin & Holmes 708 (“A growing number of statess require advice about deportation by statute or court rule”). A nonconstitutional rule requiring trial judges to inform defendants on the record of the risk of adverse immigration consequences can ensure that a defendant receives needed information without putting a large number of criminal convictions at risk; and because such a warning would be given on the record, courts would not later have to determine whether the defendant was misrepresenting the advice of counsel. Likewise, flexible statutory procedures for withdrawing guilty pleas might give courts appropriate discretion to determine whether the interests of justice would be served by allowing a particular defendant to withdraw a plea entered into on the basis of incomplete information. Cf. United States v. Russell, 686 F. 2d 35, 39-40 (CADC 1982) (explaining that a district court’s discretion to set aside a guilty plea under the Federal Rules of Criminal Procedure should be guided by, among other considerations, “the possible existence of prejudice to the government’s case as a result of the defendant's untimely request to stand trial” and “the strength of the defendant’s reason for withdrawing the plea, including whether the defendant asserts his innocence of the charge”).

Fourth, the Court’s decision marks a major upheaval in Sixth Amendment law. This Court decided Strickland in 1984, but the majority does not cite a single case, from this or any other federal court, holding that criminal defense counsel’s failure to provide advice concerning the removal consequences of a criminal conviction violates a defendant’s Sixth Amendment right to counsel. As noted above, the Court’s view has been rejected by every Federal Court of Appeals to have considered the issue thus far. See, e.g., Gonzalez, 202 F. 3d, at 28; Banda, 1 F. 3d, at 355; Chin & Holmes 697, 699. The majority appropriately acknowledges that the lower courts are “now quite experienced with applying Strickland,” ante, at 372, but it casually dismisses the longstanding and unanimous position of the lower federal courts with respect to the scope of criminal defense counsel’s duty to advise on collateral consequences.

The majority seeks to downplay its dramatic expansion of the scope of criminal defense counsel’s duties under the Sixth Amendment by claiming that this Court in Hill v. Lockhart, 474 U. S. 52 (1985), similarly “applied Strickland to a claim that counsel had failed to advise the client regarding his parole eligibility before he pleaded guilty. ” Ante, at 371. That characterization of Hill obscures much more than it reveals. The issue in Hill was whether a criminal defendant’s Sixth Amendment right to counsel was violated where counsel misinformed the client about his eligibility for parole. The Court found it “unnecessary to determine whether there may be circumstances under which erroneous advice by counsel as to parole eligibility may be deemed constitutionally ineffective assistance of counsel, because in the present case we conclude that petitioner's allegations are insufficient to satisfy the Strickland v. Washington requirement of ‘prejudice.’ ” 474 U. S., at 60. Given that Hill expressly and unambiguously refused to decide whether criminal defense counsel must avoid misinforming his or her client as to one consequence of a criminal conviction (parole eligibility), that case plainly provides no support whatsoever for the proposition that counsel must affirmatively advise his or her client as to another collateral consequence (removal). By the Court’s strange logic, Hill would support its decision here even if the Court had held that misadvice concerning parole eligibility does not make counsel’s performance objectively unreasonable. After all, the Court still would have “applied Strickland” to the facts of the case at hand.

II

While mastery of immigration law is not required by Strickland, several considerations support the conclusion that affirmative misadvice regarding the removal consequences of a conviction may constitute ineffective assistance.

First, a rule prohibiting affirmative misadvice regarding a matter as crucial to the defendant’s plea decision as deportation appears faithful to the scope and nature of the Sixth Amendment duty this Court has recognized in its past cases. In particular, we have explained that “a guilty plea cannot be attacked as based on inadequate legal advice unless counsel was not ‘a reasonably competent attorney’ and the advice was not ‘within the range of competence demanded of attorneys in criminal cases.’” Strickland, 466 U. S., at 687 (quoting McMann v. Richardson, 397 U. S. 759, 770, 771 (1970); emphasis added). As the Court appears to acknowledge, thorough understanding of the intricacies of immigration law is not “within the range of competence demanded of attorneys in criminal cases.” See ante, at 369 (“Immigration law can be complex, and it is a legal specialty of its own. Some members of the bar who represent clients facing criminal charges, in either state or federal court or both, may not be well versed in it”). By contrast, reasonably competent attorneys should know that it is not appropriate or responsible to hold themselves out as authorities on a difficult and complicated subject matter with which they are not familiar. Candor concerning the limits of one's professional expertise, in other words, is within the range of duties reasonably expected of defense attorneys in criminal cases. As the dissenting judge on the Kentucky Supreme Court put it, “I do not believe it is too much of a burden to place on our defense bar the duty to say, T do not know.’ ” 253 S. W. 3d 482, 485 (2008).

Second, incompetent advice distorts the defendant's decisionmaking process and seems to call the fairness and integrity of the criminal proceeding itself into question. See Strickland, 466 U. S., at 686 (“In giving meaning to the requirement [of effective assistance of counsel], we must take its purpose — to ensure a fair trial — as the guide”). When a defendant opts to plead guilty without definitive information concerning the likely effects of the plea, the defendant can fairly be said to assume the risk that the conviction may carry indirect consequences of which he or she is not aware. That is not the ease when a defendant bases the decision to plead guilty on counsel's express misrepresentation that the defendant will not be removable. In the latter case, it seems hard to say that the plea was entered with the advice of constitutionally competent counsel — or that it embodies a voluntary and intelligent decision to forsake constitutional rights. See ibid. (“The benchmark for judging any claim of ineffectiveness must be whether counsel's conduct so undermined the proper functioning of the adversarial process that the trial cannot be relied on as having produced a just result”).

Third, a rule prohibiting unreasonable misadvice regarding exceptionally important collateral matters would not deter or interfere with ongoing political and administrative efforts to devise fair and reasonable solutions to the difficult problem posed by defendants who plead guilty without knowing of certain important collateral consequences.

Finally, the conclusion that affirmative misadvice regarding the removal consequences of a conviction can give rise to ineffective assistance would, unlike the Court's approach, not require any upheaval in the law. As the Solicitor General points out, “[t]he vast majority of the lower courts considering claims of ineffective assistance in the plea context have [distinguished] between defense counsel who remain silent and defense counsel who give affirmative misadvice.” Brief for United States as Amicus Curiae 8 (citing cases). At least three Courts of Appeals have held that affirmative misadvice on immigration matters can give rise to ineffective assistance of counsel, at least in some circumstances. And several other Circuits have held that affirmative misadvice concerning nonimmigration consequences of a conviction can violate the Sixth Amendment even if those consequences might be deemed “collateral.” By contrast, it appears that no court of appeals holds that affirmative misadvice concerning collateral consequences in general and removal in particular can never give rise to ineffective assistance. In short, the considered and thus far unanimous view of the lower federal courts charged with administering Strickland clearly supports the conclusion that the Kentucky Supreme Court’s position goes too far.

In concluding that affirmative misadvice regarding the removal consequences of a criminal conviction may constitute ineffective assistance, I do not mean to suggest that the Sixth Amendment does no more than require defense counsel to avoid misinformation. When a criminal defense attorney is aware that a client is an alien, the attorney should advise the client that a criminal conviction may have adverse consequences under the immigration laws and that the client should consult an immigration specialist if the client wants advice on that subject. By putting the client on notice of the danger of removal, such advice would significantly reduce the chance that the client would plead guilty under a mistaken premise.

III

In sum, a criminal defense attorney should not be required to provide advice on immigration law, a complex specialty that generally lies outside the scope of a criminal defense attorney’s expertise. On the other hand, any competent criminal defense attorney should appreciate the extraordinary importance that the risk of removal might have in the client’s determination whether to enter a guilty plea. Accordingly, unreasonable and incorrect information concerning the risk of removal can give rise to an ineffectiveness claim. In addition, silence alone is not enough to satisfy counsel’s duty to assist the client. Instead, an alien defendant's Sixth Amendment right to counsel is satisfied if defense counsel advises the client that a conviction may have immigration consequences, that immigration law is a specialized field, that the attorney is not an immigration lawyer, and that the client should consult an immigration specialist if the client wants advice on that subject.

Justice Scalia,

with whom Justice Thomas joins, dissenting.

In the best of all possible worlds, criminal defendants contemplating a guilty plea ought to be advised of all serious collateral consequences of conviction, and surely ought not to be misadvised. The Constitution, however, is not an all-purpose tool for judicial construction of a perfect world; and when we ignore its text in order to make it that, we often find ourselves swinging a sledge where a tack hammer is needed.

The Sixth Amendment guarantees the accused a lawyer “for his defence” against a “criminal prosecutio[n]” — not for sound advice about the collateral consequences of conviction. For that reason, and for the practical reasons set forth in Part I of Justice Alito’s concurrence, I dissent from the Court’s conclusion that the Sixth Amendment requires counsel to provide accurate advice concerning the potential removal consequences of a guilty plea. For the same reasons, but unlike the concurrence, I do not believe that affirmative misadvice about those consequences renders an attorney’s assistance in defending against the prosecution constitutionally inadequate; or that the Sixth Amendment requires counsel to warn immigrant defendants that a conviction may render them removable. Statutory provisions can remedy these concerns in a more targeted fashion, and without producing permanent, and legislatively irreparable, overkill.

* * *

The Sixth Amendment as originally understood and ratified meant only that a defendant had a right to employ counsel, or to use volunteered services of counsel. See United States v. Van Duzee, 140 U. S. 169, 173 (1891); W. Beaney, Right to Counsel in American Courts 21, 28-29 (1955). We have held, however, that the Sixth Amendment requires the provision of counsel to indigent defendants at government expense, Gideon v. Wainwright, 372 U. S. 335, 344-345 (1963), and that the right to “the assistance of counsel” includes the right to effective assistance, Strickland v. Washington, 466 U. S. 668, 686 (1984). Even assuming the validity of these holdings, I reject the significant further extension that the Court, and to a lesser extent the concurrence, would create. We have until today at least retained the Sixth Amendment’s textual limitation to criminal prosecutions. “[W]e have held that ‘defence’ means defense at trial, not defense in relation to other objectives that may be important to the accused.” Rothgery v. Gillespie County, 554 U. S. 191, 216 (2008) (Alito, J., concurring) (summarizing cases). We have limited the Sixth Amendment to legal advice directly related to defense against prosecution of the charged offense — advice at trial, of course, but also advice at postindictment interrogations and lineups, Massiah v. United States, 377 U. S. 201, 205-206 (1964); United States v. Wade, 388 U. S. 218, 236-238 (1967), and in general advice at all phases of the prosecution where the defendant would be at a disadvantage when pitted alone against the legally trained agents of the state, see Moran v. Burbine, 475 U. S. 412, 430 (1986). Not only have we not required advice of counsel regarding consequences collateral to prosecution, we have not even required counsel appointed to defend against one prosecution to be present when the defendant is interrogated in connection with another possible prosecution arising from the same event. Texas v. Cobb, 532 U. S. 162, 164 (2001).

There is no basis in text or in principle to extend the constitutionally required advice regarding guilty pleas beyond those matters germane to the criminal prosecution at hand— to wit, the sentence that the plea will produce, the higher sentence that conviction after trial might entail, and the chances of such a conviction. Such matters fall within “the range of competence demanded of attorneys in criminal cases,” McMann v. Richardson, 397 U. S. 759, 771 (1970). See id., at 769-770 (describing the matters counsel and client must consider in connection with a contemplated guilty plea). We have never held, as the logic of the Court’s opinion assumes, that once counsel is appointed all professional responsibilities of counsel — even those extending beyond defense against the prosecution — become constitutional commands. Cf. Cobb, supra, at 171, n. 2; Moran, supra, at 430. Because the subject of the misadvice here was not the prosecution for which Jose Padilla was entitled to effective assistance of counsel, the Sixth Amendment has no application.

Adding to counsel’s duties an obligation to advise about a conviction’s collateral consequences has no logical stopping point. As the concurrence observes:

“[A] criminal convictio[n] can carry a wide variety of consequences other than conviction and sentencing, including civil commitment, civil forfeiture, the loss of the right to vote, disqualification from public benefits, ineligibility to possess firearms, dishonorable discharge from the Armed Forces, and loss of business or professional licenses____All of those consequences are seriou[s]’____” Ante, at 376 (Alito, J., concurring in judgment).

But it seems to me that the concurrence suffers from the same defect. The same indeterminacy, the same inability to know what areas of advice are relevant, attaches to misadvice. And the concurrence’s suggestion that counsel must warn defendants of potential removal consequences, see ante, at 387 — what would come to be known as the “Padilla warning’’ — cannot be limited to those consequences except by judicial caprice. It is difficult to believe that the warning requirement would not be extended, for example, to the risk of heightened sentences in later federal prosecutions pursuant to the Armed Career Criminal Act, 18 U. S. C. § 924(e). We could expect years of elaboration upon these new issues in the lower courts, prompted by the defense bar’s devising of ever-expanding categories of plea-invalidating misadvice and failures to warn — not to mention innumerable evidentiary hearings to determine whether misadvice really occurred or whether the warning was really given.

The concurrence’s treatment of misadvice seems driven by concern about the voluntariness of Padilla’s guilty plea. See ante, at 385-386. But that concern properly relates to the Due Process Clauses of the Fifth and Fourteenth Amendments, not to the Sixth Amendment. See McCarthy v. United States, 394 U. S. 459, 466 (1969); Brady v. United States, 397 U. S. 742, 748 (1970). Padilla has not argued before us that his guilty plea was not knowing and voluntary. If that is, however, the true substance of his claim (and if he has properly preserved it) the state court can address it on remand. But we should not smuggle the claim into the Sixth Amendment.

The Court’s holding prevents legislation that could solve the problems addressed by today’s opinions in a more precise and targeted fashion. If the subject had not been constitutionalized, legislation could specify which categories of misadvice about matters ancillary to the prosecution invalidate plea agreements, what collateral consequences counsel must bring to a defendant’s attention, and what warnings must be given. Moreover, legislation could provide consequences for the misadvice, nonadvice, or failure to warn, other than nullification of a criminal conviction after the witnesses and evidence needed for retrial have disappeared. Federal immigration law might provide, for example, that the near-automatic removal which follows from certain criminal convictions will not apply where the conviction rested upon a guilty plea induced by counsel’s misadvice regarding removal consequences. Or legislation might put the government to a choice in such circumstances: Either retry the defendant or forgo the removal. But all that has been precluded in favor of today’s sledge hammer.

In sum, the Sixth Amendment guarantees adequate assistance of counsel in defending against a pending criminal prosecution. We should limit both the constitutional obligation to provide advice and the consequences of bad advice to that well defined area. 
      
       Padilla’s crime, like virtually every drug offense except for only the most insignificant marijuana offenses, is a deportable offense under 8 U. S. C. § 1227(a)(2)(B)(i).
     
      
       In 1907, Congress expanded the class of excluded persons to include individuals who “admit” to having committed a crime of moral turpitude. Act of Feb. 20, 1907, ch. 1134, §2,34 Stat. 899.
     
      
       As enacted, the statute provided:
      “That the provision of this section respecting the deportation of aliens convicted of a crime involving moral turpitude shall not apply to one who has been pardoned, nor shall such deportation be made or directed if the court, or judge thereof, sentencing such alien for such crime shall, at the time of imposing judgment or passing sentence or within thirty days thereafter, . . . make a recommendation to the Secretary of Labor that such alien shall not be deported in pursuance of this Act.” 1917 Act, 39 Stat. 889-890.
      This provision was codified in 8 U. S. C. § 1251(b) (1994 ed.) (transferred to § 1227 (2006 ed.)). The judge's nondeportation recommendation was bind-mg on the Secretary of Labor and, later, the Attorney General after control of immigration removal matters was transferred from the former to the latter. See Janvier v. United States, 793 F. 2d 449, 452 (CA2 1986).
     
      
       Congress first identified narcotics offenses as a special category of crimes triggering deportation in the 1922 Narcotic Drug Act. Act of May 26,1922, ch. 202, 42 Stat. 596. After the 1922 Act took effect, there was some initial confusion over whether a narcotics offense also had to be a crime of moral turpitude for an individual to be deportable. See Weedin v. Moy Fat, 8 F. 2d 488, 489 (GA9 1925) (holding that an individual who committed narcotics offense was not deportable because offense did not involve moral turpitude). However, lower courts eventually agreed that the narcotics offense provision was “special,” Chung Que Fong v. Nagle, 15 F. 2d 789, 790 (CA9 1926); thus, a narcotics offense did not need also to be a crime of moral turpitude (or to satisfy other requirements of the 1917 Act) to trigger deportation. See United States ex rel. Grimaldi v. Ebey, 12 F. 2d 922, 923 (CA7 1926); Todaro v. Munster, 62 F. 2d 963, 964 (CA10 1933).
     
      
       The INA separately codified the moral turpitude offense provision and the narcotics offense provision -within 8 U. S. C. § 1251(a) (1994 ed.) under subsections (a)(4) and (a)(11), respectively. See 66 Stat. 201, 204, 206. The JRAD procedure, codified in 8 U. S. C. § 1251(b) (1994 ed.), applied only to the “provisions of subsection (a)(4),” the crimes-of-moral-turpitude provision. 66 Stat. 208; see United States v. O’Rourke, 213 F. 2d 759, 762 (CA8 1954) (recognizing that, under the 1952 INA, narcotics offenses were no longer eligible for JRADs).
     
      
       The changes to our immigration law have also involved a change in nomenclature; the statutory text now uses the term “removal” rather than “deportation.” See Calcano-Martinez v. INS, 533 U. S. 348, 350, n. 1 (2001).
     
      
       See Brief for Asian American Justice Center et al. as Amici Curiae 12-27 (providing real-world examples).
     
      
       There is some disagreement among the courts over how to distinguish between direct and collateral consequences. See Roberts, Ignorance Is Effectively Bliss: Collateral Consequences, Silence, and Misinformation in the Guilty-Plea Process, 95 Iowa L. Rev. 119, 124, n. 15 (2009). The disagreement over how to apply the direet/eollateral distinction has no bearing on the disposition of this case because, as even Justice Auto agrees, counsel must, at the very least, advise a noncitizen “defendant that a criminal conviction may have adverse immigration consequences,” post, at 375 (opinion concurring in judgment). See also post, at 387 (“I do not mean to suggest that the Sixth Amendment does no more than require defense counsel to avoid misinformation”). In his concurring opinion, Justice Auto has thus departed from the strict rule applied by the Supreme Court of Kentucky and in the two federal cases that he dtes, post, at 375-376.

       As Justice Auto explains at length, deportation consequences are often unclear. Lack of clarity in the law, however, does not obviate the need for counsel to say something about the possibility of deportation, even though it will affect the scope and nature of counsel’s advice.
     
      
       As the Commonwealth conceded at oral argument, were a defendant’s lawyer to know that a particular offense would result in the client’s deportation and that, upon deportation, the client and his family might well be killed due to circumstances in the client’s home country, any decent attorney would inform the client of the consequences of his plea. Tr. of Oral Arg. 37-38. We think the same result should follow when the stakes are not life and death but merely “banishment or exile,” Delgadillo v. Carmichael, 332 U. S. 388, 390-391 (1947).
     
      
      However, we concluded that, even though Strickland applied to petitioner’s claim, he had not sufficiently alleged prejudice to satisfy Strickland’s second prong. Hill, 474 U. S., at 59-60. This disposition further underscores the fact that it is often quite difficult for petitioners who have acknowledged their guilt to satisfy Strickland’s prejudice prong.
      Justice Auto believes that the Court misreads Hill, post, at 383-384. In Hill, the Court recognized — for the first time — that Strickland applies to advice respecting a guilty plea. 474 U. S., at 58 (“We hold, therefore, that the two-part Strickland v. Washington test applies to challenges to guilty pleas based on ineffective assistance of counsel”). It is true that Hill does not control the question before us. But its import is nevertheless clear. Whether Strickland applies to Padilla’s claim follows from Hill, regardless of the fact that the Hill Court did not resolve the particular question respecting misadvice that was before it.

       To this end, we find it significant that the plea form currently used in Kentucky courts provides notice of possible immigration consequences. Ky. Admin. Office of Courts, Motion to Enter Guilty Plea, Form AOC-491 (rev. Feb. 2003), http://courts.ky.gov/NR/rdonlyres/55ElF54E-ED5C4A30-BlD5-4C43C7ADD63C/0/491.pdf (as visited Mar. 29,2010, and available in Clerk of Court’s case file). Further, many States require trial courts to advise defendants of possible immigration consequences. See, e. g., Alaska Rule Crim. Proc. 11(c)(3)(C) (2009-2010); Cal. Penal Code Ann. §1016.5 (West 2008); Conn. Gen. Stat. §54-lj (2009); D. C. Code §16-713 (2001); Fla. Rule Crim. Proc. 3.172(c)(8) (Supp. 2010); Ga. Code Ann. § 17-7-93(c) (1997); Haw. Rev. Stat. Ann. §802E-2 (2007); Iowa Rule Crim. Proc. 2.8(2)(&)(3) (Supp. 2009); Md. Rule 4-242 (Lexis 2009); Mass. Gen. Laws, ch. 278, §29D (West 2009); Minn. Rule Crim. Proc. 15.01 (2009); Mont.

       Citizens are not deportable, but “[questions of citizenship are not always simple.” ABA Guidebook §4.20, at 113 (explaining that U. S. citizenship conferred by blood is “‘derivative,’” and that “[d]erivative citizenship depends on a number of confusing factors, including whether the citizen parent was the mother or father, the immigration laws in effect at the time of the parents’ and/or defendant’s birth, and the parents’ marital status”).
     
      
       “A disposition that is not a ‘conviction’ under state law may still be a ‘conviction’ for immigration purposes.” Id., §4.32, at 117 (citing Matter of Salamr-Regino, 23 I. & N. Dec. 223, 231 (BIA 2002) (en banc)). For example, state law may define the term “conviction” not to include a deferred adjudication, but such an adjudication would be deemed a conviction for purposes of federal immigration law. See ABA Guidebook §4.37; accord, D. Kesselbrenner & L. Rosenberg, Immigration Law and Crimes §2:1, p. 2-2 (2009) (hereinafter Immigration Law and Crimes) (“A practitioner or respondent will not even know whether the Department of Homeland Security (DHS) or the Executive Office for Immigration Review (EOIR) will treat a particular state disposition as a conviction for immigration purposes. In fact, the [BIA] treats certain state criminal dispositions as convictions even though the state treats the same disposition as a dismissal”).

United States, 548 F. 3d 327, 333-334 (CA5 2008) (concluding that counsel’s advice was not objectively unreasonable where counsel did not purport to answer questions about immigration law, did not claim any expertise in immigration law, and simply warned of ‘‘possible” deportation consequence; use of the word “possible” was not an affirmative misrepresentation, even though it could indicate that deportation was not a certain consequence).
     
      
       See Hill v. Lockhart, 894 F. 2d 1009, 1010 (CA8 1990) (en banc) (“[TJhe erroneous parole-eligibility advice given to Mr. Hill was ineffective assistance of counsel under Strickland v. Washington”); Sparks v. Sowders, 852 F. 2d 882, 885 (CA6 1988) (“[G]ross misadvice concerning parole eligibility can amount to ineffective assistance of counsel”); id., -At 886 (Kennedy, J., concurring) (“When the maximum possible exposure is overstated, the defendant might well be influenced to accept a plea agreement he would otherwise reject”); Strader v. Garrison, 611 F. 2d 61, 65 (CA4 1979) (“[T]hough parole eligibility dates are collateral consequences of the entry of a guilty plea of which a defendant need not be informed if he does not inquire, when he is grossly misinformed about it by his lawyer, and relies upon that misinformation, he is deprived of his constitutional right to counsel”).
     
      
      I do not mean to suggest that the Due Process Clause would surely provide relief. We have indicated that awareness of "direct consequences” suffices for the validity of a guilty plea. See Brady, 397 U. S., at 755 (internal quotation marks omitted). And the required colloquy between a federal district court and a defendant required by Federal Rule of Criminal Procedure 11(b) (formerly Rule 11(c)), which we have said approximates the due process requirements for a valid plea, see Libretti v. United States, 516 U. S. 29, 49-50 (1995), does not mention collateral consequences. Whatever the outcome, however, the effect of misadvice regarding such consequences upon the validity of a guilty plea should be analyzed under the Due Process Clause.
     
      
       As the Court’s opinion notes, ante, at 374, n. 15, many States — including Kentucky — already require that criminal defendants be warned of potential removal consequences.
