OPINION
An Immigration Judge ordered Uchenna Obianyo removed from the United States but granted his application for relief from removal under the Convention Against Torture (CAT). The Board of Immigration Appeals (BIA) dismissed the government’s appeal from the order granting CAT relief, and subsequently denied its motion to reconsider. Obianyo now asserts that he is a national of the United States and cannot be removed. For the following reasons, we will deny the petition for review.
Obianyo, a native of Nigeria, arrived in the United States in 1989 and became a lawful permanent resident in 1994. Obianyo was convicted of stalking in Tennessee in 1997, and again in Pennsylvania in 2000. Based on these convictions, an Immigration Judge (IJ) ordered Obianyo removed from the United States for having been convicted of two or more crimes involving moral turpitude. Obianyo was permitted to apply for asylum and cancellation of removal, as well as other relief from removal under the CAT. The IJ denied asylum and cancellation of removal, but granted withholding and deferral of removal to Nigeria. The BIA dismissed the government’s appeal in September 2004 and denied the government’s motion to reconsider in December 2004.
In the meantime, Obianyo filed a habeas corpus petition in the District Court, asserting that he cannot be removed because he is a national of the United States. He also challenged his detention in light of the IJ’s decision granting CAT relief. After Obianyo was released from detention in January 2005, he conceded to the District Court that his challenge to detention was moot, but maintained that his order of removal was unlawful based on his status as a national of the United States. The District Court dismissed Obianyo’s challenge to detention as moot in light of his release, and transferred his petition asserting nationality to this Court to be treated as a petition for review under the REAL ID Act. See Bonhometre v. Gonzales, 414 F.3d 442, 446 (3d Cir.2005).
We will deny Obianyo’s petition for review. His sole argument is that he is a national of the United States because he applied for naturalization in 1998. Because Obianyo never presented his nationality claim to the BIA, the claim is deemed unexhausted. See Popal v. Gonzales, 416 F.3d 249, 252 (3d Cir.2005). Absent exhaustion of available administrative remedies, we are without jurisdiction to consider the claim. See 8 U.S.C. § 1252(d)(1); Popal, 416 F.3d at 252-53.1
Even if we were to exercise jurisdiction over Obianyo’s unexhausted nationality claim, we would reject it. A national is either a citizen of the United States, or “a person who, though not a citizen of the United States, owes permanent allegiance to the United States.” 8 U.S.C. § 1101(a)(22). For a citizen of another country, “nothing less than citizenship will show ‘permanent allegiance to the United *392States.’ ” Salim v. Ashcroft, 350 F.3d 307, 310 (3d Cir.2003). Although Obianyo applied for naturalization, his application was eventually denied, as he concedes. Accordingly, Obianyo is not a naturalized citizen and thus not a national of the United States. We will deny his petition for review.
