   OPINION

TALLMAN, Circuit Judge:

An immigrant advocacy organization, Puente Arizona, along with individual unauthorized aliens and taxpayers of Mari-copa County (collectively “Puente”), challenge provisions of Arizona’s identity theft laws which prohibit using á false identity to obtain employment. The district court found the laws facially preempted by federal immigration policy and granted a preliminary injunction, preventing the Arizona government defendants (collectively “Arizona”) from enforcing the challenged pro: visions. Arizona appeals that preliminary injunction, and defendant Maricopa County individually appeals its liability under 42 U.S.C. § 1983 based on Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978). Bp-cause we find that the challenged laws are not preempted in all applications," we reverse the district court’s holding that the laws are likely facially preempted and we vacate the district court’s preliminary injunction. We also dismiss Maricopa County’s Monell appeal for lack of jurisdiction. We remand for consideration of the as-applied challenge to the statutes.

I

This case began when Arizona amended its identity theft laws to reach the growing problem of employment-related identity theft within the state. Arizona passed H.B. 2779 in 2007, known as the “Legal Arizona Workers Act,” which amended Arizona’s aggravated identity theft statute, A.R.S. § 13-2009. The statute now prohibits using the information of another (real or fictitious) person “with the intent to obtain employment.” A.R.S. § 13-2009. In 2008, Arizona passed H.B. 2745, titled “Employment of Unauthorized Aliens,” which expanded Arizona’s general identity theft statute to also reach employment-related identity theft. See A.R.S. § 13-2008(A).

These bills were passed, at least in part, in an effort to solve some of Arizona’s problems stemming from illegal immigration. The titles of the legislation and the legislative history show an intent on the part of Arizona legislators to prevent unauthorized aliens from coming to and remaining in the state. But these bills were also aimed at curbing the growing and well-documented problem of identity theft in Arizona. Between 2006 and 2008, Arizona had the highest per-capita identity theft rates in the nation, and one third of all identity theft complaints in the state involved employment-related fraud.

Since the laws were amended, Arizona has been aggressively enforcing employment-related identity theft. Although most of these enforcement actions have been brought against unauthorized aliens, some authorized aliens and U.S. citizens have also been prosecuted. And while many of the people prosecuted under the identity theft laws used a false identity to prove that they are authorized to work in the United States, other defendants used false documents for non-immigration related reasons. For example, Arizona has prosecuted U.S. citizens who used another individual’s identity to hide, a negative criminal history’from a potential employer.

In response tó these prosecutions, Puente - challenged the amended identity theft laws as unconstitutional for violating the Supremacy Clause and the Equal Protection Clause. In an attempt to repeal the identity theft laws, Puente sued Mari-copa County Sheriff Joseph Arpaio, Mari-copa County Attorney Bill Montgomery, Maricopa County, and the State of Arizona. On August 8, '2014; Puente moved for a preliminary injunction solely on its facial preemption claim.

Relying on recent Supreme Court precedent, Puente argued that the federal Immigration Reform and Control Act (“IRCA") established a “comprehensive framework” for regulating the employment of unauthorized aliens, and therefore Arizona’s employment-related identity theft laws were facially preempted. See Arizona v. United States, — U.S. -, 132 S.Ct. 2492, 2504, 183 L.Ed.2d 351 (2012). The District Court agreed that the laws were likely unconstitutional on their face and granted the requested preliminary injunction on conflict and field preemption grounds on January 5,2015. .

Specifically, the district court enjoined Arizona “from enforcing. A.R.S. § 13-2009(A)(3) and the portion of A.R.S. § 13-2008(A) that addresses actions committed ‘with the intent to obtain or continue employment.’ ” In the same order, the district court also denied Maricopa County’s Rule 12(b)(6) motion to dismiss under Mo-nell. Maricopa County argued that its lack of control over Sheriff Arpaio shows that he is not a final policymaker for the County. The district court rejected that argument because control is just one factor in the Monell policymaker analysis. The County moved for reconsideration and the district court again held that the Sheriff is a policymaker.

Arizona then filed this timely interlocutory appeal- challenging the district court’s preliminary injunction. Maricopa County also seeks review of the district court’s Monell holding. But there has been no final judgment entered to date, and the merits of this case remain pending in the district court. Importantly, the district court has yet to consider the merits of Puente’s as-applied preemption challenge.

II

We turn first to the preliminary injunction. Preliminary injunctive relief is subject to “limited review” on appeal. See Flexible Lifeline Sys., Inc. v. Precision Lift, Inc., 654 F.3d 989, 993-94 (9th Cir.2011). A preliminary injunction should only be set aside if the district court “abused its discretion or based its decision on an erroneous legal standard or on clearly erroneous findings of fact.” United States v. Peninsula Commc’ns, Inc., 287 F.3d 832, 839 (9th Cir.2002). The district court’s legal conclusions, such as whether a statute is preempted, are reviewed de novo. See In re Korean Air Lines Co., 642 F.3d 685, 691 n. 3 (9th Cir.2011).

To obtain a preliminary injunction, the plaintiff must prove “that- he is likely to succeed on the merits,- that he is likely to suffer irreparable harm in the absence of preliminary relief, that the balance of equities tips in his favor, and that an injunction is in the public interest.” Winter v. Nat. Res. Def. Council, Inc., 555 U.S. 7, 20, 129 S.Ct. 365, 172 L.Ed.2d 249 (2008). Here, the district court found that Puente met its burden on each element of the Winter test. We disagree, and hold that Puente is not likely to succeed on, and has not raised serious questions about, the merits of its facial challenge. This conclusion is guided by principles of preemption jurisprudence and the unique burdens imposed on facial challenges.

We first address long-held principles of preemption. Congress of course has the power, under the Supremacy Clause, to preempt state law. Arizona, 132 S.Ct. at ,2500. Congress may exercise this power expressly or preemption may be implied where, the state law is in an area fully occupied by federal regulation or where it conflicts with federal law. Id. at 2500-01.

There are two types of conflict preemption. ■ Id. at 2501. Conflict preemption occurs where (1) it is impossible to comply with both federal and state law, or (2) where the state law “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.” Id. (quoting Hines v. Davi-dowitz, 312 U.S. 52, 67, 61 S.Ct. 399, 85 L.Ed. 581 (1941)). Field preemption' can also take two forms. A law is field preempted where (1) the “regulatory framework is so pervasive” that there is no room f<?r state regulation, or (2) where the “federal interest- [is] so dominant that the federal system will be assumed to preclude enforcement of state laws on the same subject.” Id. (quoting Rice v. Santa Fe Elevator Corp., 331 U.S. 218, 230, 67 S.Ct. 1146, 91 L.Ed. 1447 (1947)).

. In both field and conflict preemption cases, the touchstone of our inquiry is congressional intent. Wyeth v. Levine, 555 U.S. 555, 565, 129 S.Ct. 1187, 173 L.Ed.2d 51 (2009). When analyzing congressional intent “we start with the assumption that the historic police powers of the States were not to be superseded by the Federal Act unless that was the clear and manifest purpose of Congress.” Id (quoting Rice, 331 U.S. at 230, 67 S.Ct. 1146). Puente argues that this presumption against preemption does not apply here because the identity theft laws do not regulate in an area of historic state power. We reject this argument because, while the identity theft laws certainly have effects in the area of immigration, the text, of the laws regulate for the health and safety of the people of Arizona. See Medtronic Inc. v. Lohr, 518 U.S. 470, 475, 116 S.Ct. 2240, 135 L.Ed.2d 700 (1996). Therefore, only if Congress’s intent to preempt the challenged state statute is “clear and manifest” may we deem the statute preempted. See Wyeth, 555 U.S. at 565, 129 S.Ct. 1187,

We are also guided by the rules that apply to facial challenges. United States v. Salerno, 481 U.S. 739, 746, 107 S.Ct. 2095, 95 L.Ed.2d 697 (1987), instructs that to succeed on a facial challenge the plaintiff must show that “no set of circumstances, exists under which the Act would be valid.” Salerno’s applicability in preemption cases is not entirely clear, however. In the First Amendment context, the Supreme Court recognizes a type of facial challenge in which a statute will be invalidated as overbroad if “a substantial number of its applications are unconstitutional, judged in relation to the statute’s plainly legitimate sweep.” United States v. Stevens, 559 U.S. 460, 473, 130 S.Ct. 1577, 176 L.Ed.2d 435 (2010) (quoting Washington v. Glucksberg, 521 U.S. 702, 740 n. 7, 117 S.Ct. 2258, 138 L.Ed.2d 772 (1997) (Stevens, J., concurring)). Whether ‘the “substantial number of applications” test applies to facial preemption challenges has not yet been decided by the Supreme Court. Without moré direction, wé have chosen to continue applying Salerno. United States v. Arizona, 641 F.3d 339, 345 (9th Cir.2011), aff'd in part, rev’d in part and remanded, — U.S. -, 132 S.Ct. 2492, 183 L.Ed.2d 351 (2012); Sprint Telephony PCS, L.P. v. County of San Diego, 543 F.3d 571, 579 n. 3 (9th Cir.2008) (en banc). We therefore proceed, keeping in mind.the high bar that Puente must overcome under Salerno before' we may strike down the identity theft laws on this facial challenge.

Applying the preemption and facial challenges framework discussed above, we conclude that the- identity theft laws are not facially preempted because they have obvious constitutional applications. This case is made significantly easier by the scope of Arizona’s interlocutory appeal and the text of the challenged provisions..

First, the scope of this appeal is limited. Puente moved for a preliminary'injunction based solely on its claim that the identity theft laws are facially preempted under the Supremacy Clause. See Pis.’ Mot. Prelim.' Inj., Case No. 2:14-cv-01356-DGC (D.Ariz. Aug. 8, 2014) at 1 (“[T]he challenged-provisions constitute a facially invalid state intrusion into an area of exclusive federal control.”). Based on this facial challenge, Puente asked the district court to enjoin enforcement oí-all applications of the identity theft laws. See id. The district court has yet. to address Puente’s as-applied, challenge, and without a fully developed record we think it inappropriate now to enjoin only certain applications of the. identity theft laws. See 16 C.J.S. Constitutional Law § 243 (2016) (discussing the importance of factual findings on an as-applied challenge).

Second, we think it significant that the identity theft laws are textually neutral— that is, they apply to unauthorized aliens, authorized aliens, and U.S. citizens alike. Both A.R.S. § 13-2009(A)(3) and Á.R.S. § 13-2008(A) sanction “[a]ny person” who commits identity theft to obtain employment. As noted in hypotheticals raised at oral argument, these laws could easily be applied to a sex offender who uses a false identity to get á job at a daycare center. Or the laws could be applied to stop a convicted felon from lying about his criminal history on a job application for a position of trust. In fact, Arizona has prosecuted U.S. citizens for doing just that. The key point is this: one could not tell that the identity theft laws .undermine federal immigration policy by looking at the text itself. Only when studying certain applications of the laws do immigration conflicts arise.

Bearing in mind the scope of our review and the statutory language, we now turn to the ultimate question: Are the identity theft laws facially preempted by federal immigration law?

Puente argues that the identity theft laws are in conflict with -and are field preempted by IRCA. Puente contends that the identity theft laws are preempted for three reasons: (1) the laws were passed with an intent to regulate immigration; (2) the laws conflict with the federal government’s choice of sanctions and exclusive prosecutorial discretion for immigration-related crimes; - and (3) the laws conflict with the text of IRCA. We reject all three of these arguments. Although there is tension between the federal scheme and some applications of the identity theft laws, we hold that this tension is not enough to rise to the level of a “clear and manifest purpose” to preempt the identity theft laws in their entirety. See Wyeth, 555 U.S. at 565, 129 S.Ct. 1187.

■The parties argue vigorously about the import of state’ legislative history in this case. But these-arguments about whether to look to state legislative history'miss the mark in two ways. First, Arizona’s legislative history tells us nothing about whether Congress intended to preempt state statutes like the identity theft laws. If Congress intended to preempt laws like the.one.challenged here, it*would not matter what Arizona’s motives were; the laws would clearly be preempted.-

Second, when we do look to state action, we look primarily to a statute’s effects to determine ■ if the state encroached on an area Congress intended to reserve. See Gade v. Nat’l Solid Wastes Mgmt. Ass’n, 505 U.S. 88, 105, 112 S.Ct. 2374, 120 L.Ed.2d 73 (1992). Said another way, it does not matter if Arizona passed the identity theft laws for a good or bad purpose — what matters is whether the legislature succeeded in carrying out that purpose. See Hughes v. Oklahoma, 441 U.S. 322, 336, 99 S.Ct. 1727, 60 L.Ed.2d 250 ,(1979) (“[W]hen considering the purpose of a challenged statute, [courts are] not bound by ‘[t]he name, description or characterization given it by the legislature or the courts of the State,’ but will determine for [themselves] the practical impact of the law.” (internal quotation omitted)). Thus, the crucial question is whether Congress intended to preempt the identity theft laws given the practical effect of those laws. We think not.

We agree with Puente and the district court that the legislative history of both H.B. 2779 and H.B. 2745 show an intent on the part of Arizona legislators to prevent unauthorized aliens from remaining in the state. But if that was the legislature’s only goal, it failed. The legislature also rectified the growing problem of employment-related identity theft. We think Congress would agree that the identity theft laws validly, apply to any person who uses another’s identity for non-immigration reasons. There is evidence in the record that the laws have been applied to people who use another’s identity to hide their criminal record. Congress could not have intended to preempt the state from sanctioning crimes that protect citizens of the state under Arizona’s traditional police powers without intruding on federal immigration policy. Thus, we hold that despite the state legislative history, Congress - did not intend to preempt state criminal statutes like the identity theft laws.

Next, Puente argues that the identity theft laws are preempted because they conflict with the federal government’s enforcement techniques and exclusive discretion in the area of immigration. In making these arguments, Puente relies heavily on the Supreme Court’s decision in Arizona. There, the Supreme Court struck down a state law that made it a misdemeanor for “an unauthorized alien to knowingly apply for work, solicit work in a public place or perform work as an employee or independent contractor.” Arizona, 132 S.Ct. at 2503.

The Arizona Court held that this statute was in conflict with IRCA’s “comprehensive framework for combating the. employment of illegal aliens.” Id. at 2504 (internal quotation omitted). Examining the legislative history of IRCA, the Court pointed to failed proposals to criminalize unauthorized aliens applying for work. Id. Because Congress “made a deliberate choice” to punish' employers instead of employees with criminal sanctions under IRCA Arizona’s attempt to create a crime on the.employee-side conflicted “with the careful balance struck by Congress” in this area. Id. at 2504-05. Essentially, this conflict in statutory remedies between the federal and state statutes rendered the state statute unconstitutional. Id. at 2505'. Puente argués that a: similar conflict in techniques is present here because the identity theft' laws authorize different (and generally harsher) punishments' than authorized under federal law,

Puente also argues that the identity theft laws deprive the United States of necessary prosecutorial discretion over immigration-related crimes. We recently found this argument persuasive in Valle del Sol. 732 F.3d at 1027; see also Arizona Dream Act Coal. v. Brewer, No. 15-15307, 818 F.3d 901, 909-11, 2016 WL 1358378, at *6 (9th Cir. Apr. 5, 2016) (explaining that the Executive has “very broad discretion” to determine immigration enforcement priorities). The statute at issue in Valle del Sol criminalized harboring and transporting unauthorized aliens. Valle del Sol, 732 F.3d at 1012-13. The harboring statute in Valle del Sot “divest[ed] federal authorities of the exclusive power to prosecute these crimes”'in line with federal priorities. Id. at 1027. Because Arizona had given itself the power to prosecute harboring crimes in state court it could do so “in a manner unaligned with federal immigration enforcement priorities.” Id. This co-opting of federal discretion over enforcement, coupled with different statutory penalties under state law, led the Valle del Sol court to hold Arizona’s harboring statute unconstitutional. Id., at 1029. Puente argues that like .the harboring statute in Valle del Sol, the identity theft laws undermine federal discretion to punish immigration-related fraud in' line with federal priorities.

While these arguments may be persuasive in the context of . Puente's as-applied challenge,.we.do not find .them persuasive in a facial attack. Arizona, Valle del Sol, and their progeny are easily distinguishable from this case. .,In those cases, the contested state statutes, on their face, applied only to unauthorized aliens, so every application of the-statute had the potential to conflict with federal immigration policy. In contrast, ■ the statutes at issue here make it a crime for “any person” to use a false document to gain employment.

Athough some applications of the identity theft laws may come, into conflict with IRCA’s “comprehensive scheme” or with the federal government’s exclusive discretion-over immigration-related prosecutions, when the laws are applied ..to U.S. citizens or lawful permanent residents those concerns are not; implicated. Thus, Arizona, Valle del Sol, and-all other preemption cases where the statutory language singles out unauthorized aliens,, do not control here. In this case, Arizona-exercised its police powers to pass criminal laws that apply equally to unauthorized aliens, authorized aliens, and'U.S. citizens. Just because some applications of those laws implicate feideral immigration priorities does not mean that the- statute as a whole should be struck down. ■

Finally, Puente makes an argument for preemption based on the text of IRCA. Puente argues that IRCA was drafted to allow only federal government» prosecutions of those-who use false documents to obtain employment. < d See 8 U.S.C. §§ 1324a(b)(5), (d)(2)(F)-(G). In particular, IRCA provides .that any information employees submit to indicate their work status “may not be used” for' purposes other than prosecution under specified federal criminal statutes for fraud, perjury, and related -conduct. Id. § 1324a(b)(5).

Again, we reject this argument because this is á facial challenge and this argument applies-only to -certain- applications of the statute not evident from the statute’s text. IRCA’s document use limitation is only violated when the identity theft laws are applied in ways that rely on the Form 1-9 and attached documents. ¡ Just because Arizona could (and has in the past) enforced the identity theft laws in violation of IRCA’s document usé limitation does not mean the laws should be struck down in their entirety. Arizona retains the power to enforce the laws in ways that do not implicate federal immigration priorities. While the district court may. ultimately decide to enjoin- -identity theft enforcement actions which rely on 1-9 documents, that is not a reason to strike down the laws in their entirety.

In sum, we reject all of Puente’s arguments because each one applies to only certain applications of the identity theft laws. - Accordingly, Puente has not met its burden of showing a clear and manifest purpose to completely preempt these laws. See Cal. Div. of Labor Standards Enf't v. Dillingham Const., N.A., 519 U.S. 316, 334, 117 S.Ct. 832, 136 L.Ed.2d 791 (1997) (“We could not hold pre-empted a. state law in an area of traditional state-regulation based on so tenuous a- relation without doing grave violence to our presumption that Congress intended fiothing of the sort.”). Because Puente has not come forward with a compelling reason why the statute is preempted on its face, we hold that Puente has-not raised a serious question going to the merits of its facial challenge.

We stress again that the only question for us to answer on this facial challenge is whether the identity theft laws should be enjoined in all contexts as applied, to all parties. On this record, we cannot say that every application is unconstitutional. Thus, we vacate the district court’s preliminary injunction and reverse its. finding that Puente’s facial challenge is likely to succeed on the merits. In doing so, we make no comment on the viability of Puente’s as-applied challenge still,pending in the district court. . -,

III

We now turn to Maricopa County’s Monell appeál. The district court found that Sheriff Arpaio is a policymaker for Maricopa County. Accordingly, the Court held that the County can be liable for the Sheriff’s actions under § 1983 based on Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978). The.County attempts to appeal this ruling, arguing, that it has no control over the Sheriff, a state official under Arizona law, so it should not be liable for his actions. In response, Puente argues that this issue is not properly before the court on an ■ interlocutory preliminary injunction appeal. We agree.

Generally parties must wait for final judgment to appeal a district court’s ruling. . See 28 U.S.G. § 1291, But in some circumstances an interlocutory order is immediately appealable by statute — for example, when an interlocutory order grants an injunction. Id § 1292(a)(1). In that case, we may exercise pendent jurisdiction over issues outside the injunction only if the issue is “inextricably intertwined” with or “necessary to ensure meaningful review of” the injunction. Meredith v. Oregon, 321 F.3d 807, 812-13 (9th Cir.), amended, 326 F.3d 1030 (9th Cir.2003) (quoting Swint v. Chambers Cty. Comm’n, 514 U.S. 35, 51, 115 S.Ct. 1203, 131 L.Ed.2d 60 (1995)).

Since 1995, the Supreme Court has made clear that invocation of pendent jurisdiction should, be extremely limited. See Swint, 514 U.S. at 45-48, 115 S.Ct. 1203. Post-Sivint, we have been hesitant to find pendent jurisdiction and we interpret the “inextricably intertwined” standard narrowly. Meredith, 321 F.3d at 813-15. The standard is only satisfied where the issues are “(a) [ ] so intertwined that we must decide the pendent issue in order to review the claims properly raised on interlocutory appeal, or (b) resolution of the issue properly raised on interlocutory appeal necessarily resolves the pendent issue.” Cunningham v. Gates, 229 F.3d 1271, 1285 (9th Cir.2000), as amended (Oct. 31, 2000) (internal citations omitted).

Issues are not “inextricably intertwined” when courts apply different legal standards to each issue. Id For example, in Swint, the Supreme Court held the Eleventh Circuit erred in exercising pendent jurisdiction over a county’s Monell liability, in part, because that issue could not be “inextricably intertwined” with the proper subject of the interlocutory appeal — qualified immunity. Swint, 514 U.S. at 51, 115 S.Ct. 1203. The Swint Court suggested that a premature Monell appeal could not be bootstrapped onto a proper qualified immunity interlocutory appeal because the issues involved different legal inquiries. See id. While “qualified immunity turns on-whether [individuals] violated clearly established- federal law,-” a county’s liability under Monell for the sheriffs actions turned “on the allocation of law enforcement power.” Id Even though the issues shared common facts, that was not enough to confer pendent jurisdiction where the issues involved different legal tests. See id.; see also Cunningham, 229 F.3d at 1285.

Post-Swint; we have found pendent jurisdiction in two narrow categories of cases. First, jurisdiction is proper when the- pendent issue implicates “the very power the district court used to issue the rulings” under review. Hendricks v. Bank of Am., 408 F.3d 1127, 1134-35 (9th Cir.2005) (quoting Meredith, 321 F.3d at 816). For example, we have exercised jurisdiction over issues of subject' matter jurisdiction and personal jurisdiction when attending an interlocutory appeal. Id.; Smith v. Arthur Andersen LLP, 421 F.3d 989, 998 (9th Cir.2005). Issues, such as jurisdiction, which question the authority of the court are “necessary ‘ to ensure meaningful review of’ injunctions because if the appellate court does not have jurisdiction then it does not have the authority to address any issue on appeal. See Hendricks, 408 F.3d at 1134.

Second, we have also . exercised pendent jurisdiction over a small set. of cases, where ruling on the merits of the proper interlocutory appeal will necessarily resolve all of the remaining issues presented by the pendent appeal. See Huskey v. City of San Jose, 204 F.3d 893, 905 (9th Cir.2000). To illustrate, in Huskey we held that a city’s Monell appeal in a § 1983 case was “inextricably intertwined” with an individual defendant’s appeal from a denial of summary judgment based on qualified immunity. Id. at 904-05. There, we reversed the district court’s denial of qualified immunity for a city attorney because the plaintiff failed to show a constitutional violation. Id. at 902. Since this decision “necessarily foreclose^] the possibility of the [cjity’s §. 1983 liability,” we exercised pendent jurisdiction over the city’s Monell liability. and held that the district court erred , in denying the city’s motion for summary judgment. .Id. at 904.

We hold that we do not have pendent jurisdiction over Maricopa County’s Monell. liability. A district court’s, order denying a. county’s motion to dismiss under Monell is generally not -immediately ap-pealable. See Collins v. Jordan, 110 F.3d 1363, 1366 n.1 (9th Cir.1996). Thus, we must find that the County’s Monell liability is “inextricably intertwined” with the preliminary- injunction to address the merits ,of the County’s argument. The fact that the parties briefed the Monell issue separately is a good indicator that it involves different legal standards from the injunction appeal. Just as the Supreme Court refused to exercise pendent jurisdiction in Swint because issues of Monell liability and qualified immunity involve different legal tests, we refuse to combine a Monell appeal with an action revolving around application of the Winter test and preemption principles. These legal inquiries are analytically distinct.

Nor does the Monell issue fall within one of the narrow categories of pendent jurisdiction. The Monell issue does not question the district court’s authority to impose an injunction. Unlike jurisdictional issues and certain immunities from suit, Monell-is just a defense to liability. See Swint, 514 U.S. at 43, 115 S.Ct. 1203. If a county can show that the alleged wrongdoer is not a policymaker that does not mean the -court is without power to hear the case, it simply means the court should grant judgment for the county.

Finally, -because we reverse the district court’s preliminary injunction and remand for further proceedings, this case is also unlike the' Huskey line of cases where ruling on the interlocutory appeal necessarily' resolves the pendent appeal. In Huskey, we agreed to hear a city’s premature' appeal because we had already decided the plaintiff could not succeed on his § 1983 claim and therefore the city could not be liable. This case is inapposite— here we do not comment on the merits of Puente’s as-applied preemption challenge or its equal protection challenge, both of which remain pending, and should be addressed in the first instance by the district court. Thus, our ruling on the preliminary injunction today does not resolve the County’s ultimate liability in this case.

Because this case does not fall within one of the narrow categories where invoking pendent jurisdiction is proper, we dismiss Maricopa County’s appeal for. lack of jurisdiction.

IV

We hold that Arizona’s employment-related identity theft laws are not preempted in all applications. We reverse the district court’s finding that the laws are likely facially preempted. We also vacate the district court’s preliminary injunction and remand with instructions to evaluate the merits of Puente’s remaining claims, including ' the as-applied preemption challenge. . Finally, we dismiss Maricopa County’s Monell appéal for lack of jurisdiction without prejudice to renew that argument before final judgment is rendered. ,s

Each.party shall bear its own costs on appeal.

REVERSED in part, injunction VACATED, DISMISSED in part, and REMANDED with instructions. 
      
      . We use the term “unauthorized alien” throughout this opinion to refer to “aliens who have entered or are present in the United States in violation of .federal immigration law.” Valle del Sol Inc. v. Whiting, 732 F.3d 1006, 1012 n. 1 (9th Cir.2013).

      i For thp sake of simplicity, we will refer to these challenged provisions as the “identity theft laws.”
     
      
      . Because the Ninth Circuit utilizes a "sliding scale” approach to the Winter test, a preliminary injunction is also appropriate when a plaintiff raises "serious questions” as to the merits and '"the balance of hardships tips sharply in [plaintiff’s] favor.” All. for the Wild Rockies v. Cottrell, 632 F.3d 1127, 1135 (9th Cir.2011) (internal quotations omitted).
     
      
      . The Supreme Court rejected a similar argument in Wyeth and applied the presumption ágainst preemption even though the state fort claim at issue in that case touched on an area of historic federal regulation. See Wyeth, 555 U.S. at 565 n. 3, 129 S.Ct. 1187.
     
      
      . The Supreme Court’s .majority opinion in Arizona does not cite Salerno, which has led some courts to conclude Salerno does not apply to facial preemption challenges. See Lozano v. City of Hazleton, 724 F.3d 297, 313 n, 22 (3d Cir.2013). Lozano is an immigration preemption case in which the Third Circuit essentially found a strict application of Salerno's rule incompatible with substantive preemption doctrine. See ■ id. The district court in this case employed Lozano's reasoning to hold, that Salerno should not apply here, Salerno remains binding law in the Ninth Circuit, however, and we are not free to ignore it. Sprint Telephony, 543 F.3d at 579 n. 3 ("In cases involving federal preemption of a local statute, ... the [Salerno ] rule applies with full force.”).
     
      
      . We thank the United States for filing a ; helpful amicus brief in this matter, but we decline to implement their suggestion to engage in an as-applied analysis. The United States agrees with us that the identity theft laws are constitutional on their face but has asked us to narrow the preliminary injunction to prohibit two applications of the laws: (1) enforcement actions that rely on the Form I-9, and (2) prosecutions of “fraud committed to demonstrate work authorization under federal immigration law.” On this facial challenge we decline to enjoin certain applications of the laws. The question of which applications of the laws are preempted is properly left for the district court, which has yet to . rule or create a suitable record on Puente’s as-applied challenge.
     
      
      , We do not mean to suggest that the state’s purpose in passing a statute is not relevant to our preemption analysis, as both this court and the Supreme Court have analyzed purpose in preemption cases. See N.Y. State Conf. of Blue Cross & Blue Shield Plans v. Travelers Ins. Co., 514 U.S. 645, 658, 115 S.Ct. 1671, 131 L.Ed.2d 695 (1995); Tillison v. City of San Diego, 406 F.3d 1126, 1129 (9th Cir.2005). In accordance • with Supreme Court precedent, we hold only that state legislative purpose is not dispositive. See Perez v. Campbell, 402 U.S. 637, 651-52, 91 S.Ct. 1704, 29 L.Ed.2d 233 (1971) (overruling prior preemption cases that focused on "the purpose rather than the effect of state laws”).
     
      
      . On remand, Puente may again produce evidence of the Arizona'legislature's intent to regulate immigration when asking the district court to enjoin certain immigration-related applications of the identity theft laws. We hold only that this legislative history is not sufficient to doom the statutes where they can be validly applied in ways that do not implicate immigration.
     
      
      . The list of cases analyzing preemption in the immigration context is large and continuously growing. The vast majority of these cases analyze statutes or government actions that apply only to unauthorized aliens. See, é.g., Arizona v. Brewer, No. 15-15307, 818 F.3d at 914-15, 2016 WL 1358378, at *10 (explaining why the policy at issue in that case applied' to only unauthorized aliens and highlighting other similar cases).
     
      
      . In Monell, the Supreme Court held that local governments can be liable under § 1983 for constitutional violations resulting from “policy or custom ... made by its lawmakers or by those whose edicts or acts may fairly be said to represent official policy.” 436 U.S. at 694, 98 S.Ct. 2018.
