   OPINION OF THE COURT

JORDAN, Circuit Judge.

Dzevat Ljubanovic petitions for review of a decision by the Board of Immigration Appeals (“BIA”) denying his application for asylum, withholding of removal, and protection under the Convention Against Torture (“CAT”). Because we conclude that we lack jurisdiction to review Ljuba-novie’s claims, we will dismiss the petition for review.

I. Background

Ljubanovic entered the United States on May 17, 2001. He filed an application for asylum, withholding of removal, and protection under the CAT in May 2002. On the application, Ljubanovic listed his nationality as Yugoslavian and his ethnicity as Albanian. As a matter of course, the application was forwarded to the Department of State for comment. In September 2004, following the formation of Serbia-Montenegro from portions of the former Yugoslavia, Ljubanovic filed a second supplemental application for relief. Unlike his first application, the second was not forwarded to the Department of State for comment.

In affidavits attached to his applications, Ljubanovic stated that the police arrested him in 1991 because he was an ethnic Albanian, held him for twenty-four hours', and beat him severely. He also stated that, beginning in 1992, the Yugoslavian military police attempted to conscript him to fight in Kosovo against other ethnic Albanians. According to Ljubanovic, he managed to avoid the military police until 1998, when they caught him and forced him to serve in the Yugoslavian army. Ljubanovic claimed that, prior to inducting him into the army, the military imprisoned him for several days, beat him, and threatened him with death. He alleged that the military then released him from prison, inducted him into the army, and forced him to perform hard labor. Ljubanovic further claimed that after eleven months of service, a friend, who is also Albanian, overheard officers planning to kill both of them because of their ethnicity. Ljubano-vic stated that his friend stole a military stamp used to indicate when a draftee’s term of service was completed, and he and his friend used the stamp to alter their military documents and then escaped. Ljubanovic’s affidavits explained that he did not want to leave the United States because he feared that, if repatriated, he would be arrested as a deserter and persecuted and tortured by the police.

On March 31, 2005, the Immigration Judge (“IJ”) held a hearing on Ljubano-vic’s applications. Ljubanovic was present and represented by counsel. At the hearing, he testified in accordance with his affidavits. The IJ denied all Ljubanovic’s claims for relief. Ljubanovic filed a timely appeal to the BIA, which summarily affirmed the IJ’s decision. He then filed a timely petition for review with this Court.

II. Discussion

In his petition for review, Ljubanovic argues that the IJ committed two legal errors which require a remand. First, he argues that the IJ was required to send his supplemental asylum application to the Department of State for comment under 8 C.F.R. § 208.11(a), which provides that “[t]he Service shall forward to the Department of State a copy of each completed application it receives.” Second, he argues that the IJ applied an inappropriately high standard of proof to his CAT claim. According to Ljubanovic, he need not, as the IJ required, show that his torturer was “either a public official of his government or, in the alternative, someone working basically under some kind of official edict or some kind of sanctioned policy that the government has that results in such torture.” (Pet. Br. at 12 (citing Appx. at 55).) Instead, he argues that under our decision in Silva-Rengifo v. Attorney General, 473 F.3d 58 (3d Cir.2007), he need only show that “government officials remained] will-. fully blind to torturous conduct and breach[ed] their legal responsibility to prevent it.” (Pet. Br. at 15 (quoting Silva-Rengifo, 473 F.3d at 70).)

We lack jurisdiction to address either of Ljubanovic’s arguments. Ljuba-novie did not raise with the BIA his argument that the IJ was required to send his supplemental application for relief to the Department of State for comment. In addition, although he referred very generally to the legal standards governing CAT claims in his argument before the BIA, he did not refer in any way to his present contention that the IJ applied an incorrect legal standard to his CAT claim. We lack jurisdiction to address arguments in a petition for review which were not exhausted before the BIA. 8 U.S.C. § 1252(d)(1) (“A court may review a final order of removal only if the alien has exhausted all administrative remedies available to the alien as of right .... ”); see also Abdulrahman v. Ashcroft, 330 F.3d 587, 594-95 (3d Cir. 2003) (holding that we do not have jurisdiction to review arguments not raised before the BIA because they are unexhaust-ed).

Accordingly, we will dismiss the petition for review. 
      
      . We review questions of our own jurisdiction de novo. Alaka v. Attorney General, 456 F.3d 88, 94 n. 8 (3d Cir.2006) (citations omitted).
     
      
      . "Ordinarily, [we] review decisions of the ... [BIA] and not those of an IJ. When the BIA does not render its own opinion, however, and either defers or adopts the opinion of the IJ, [we] must then review the decision of the IJ.” Gao v. Ashcroft, 299 F.3d 266, 271 (3d Cir.2002) (citing Ahdulai v. Ashcroft, 239 F.3d 542, 549 n. 2 (3d Cir.2001)).
     
      
      . Ljubanovic does not challenge the IJ’s disposition of his asylum and withholding of removal claims in his brief. Therefore, we will deem those claims waived. Alaka, 456 F.3d at 94.
     
      
      . In its brief, the government contends that Ljubanovic's argument that the IJ was required to send his second application to the Department of State for comment lies outside our jurisdiction because Ljubanovic did not raise it before the BIA. However, despite Lju-banovic’s failure to raise his CAT argument before the BIA, the government addresses that argument on the merits. We conclude that both claims lie outside our jurisdiction because the government's failure to raise a jurisdictional challenge cannot waive a jurisdictional defect. Morel v. INS, 144 F.3d 248, 251 n. 3 (3d Cir. 1998) (explaining that “a party does not waive [a jurisdictional defect] by failing to challenge jurisdiction early in the proceedings.... [A] court, including an appellate court, will raise lack of subject-matter jurisdiction on its own motion.”) (citations omitted).
