Luis Puente Almaraz (Puente), a citizen of Mexico, petitions this court for review of an order denying his application for adjustment of status and ordering his removal to Mexico. The Board of Immigration Appeals (BIA) affirmed the order of the immigration judge.

Puente contends that he is eligible for an adjustment of status because 8 U.S.C. § 1255(f) exempts the ground of inadmissibility set forth in 8 U.S.C. § 1182(a)(9)(C)(i)(I). This court has previously upheld as reasonable the BIA’s determination that § 1255(i) does not exempt the ground of inadmissibility set forth in § 1182(a)(9)(C)(i)(I). Montera-Cruz v. Gonzales, 409 F.3d 246, 256 (5th Cir. 2005). Although Puente argues that this court should revisit Montera-Cruz in light of decisions from the Ninth and Tenth Circuits that interpret the § 1255 waiver more broadly, one panel of this court may not overrule a prior panel’s decision in the absence of an intervening contrary or superseding decision by this court sitting en banc or by the United States Supreme Court. See United States v. Ruff, 984 F.2d 635, 640 (5th Cir. 1993).

Finally, Puente contends that the BIA’s interpretation of § 1182(a)(9)(C)(i)(I) leaves the statute open to a constitutional attack on equal protection grounds. Puente does not identify which classes or groups of immigrants are allegedly treated differently by the BIA’s interpretation of § 1182(a)(9)(C)(i)(I). Further, this court has held that the conduct proscribed by § 1182(a)(9)(C)(i)(I) is both different from and more culpable than the conduct of an alien who is inadmissible only under § 1182(a)(6)(A)(i). Mortera-Cruz, 409 F.3d at 255-56. Therefore, Puente’s con-clusional equal protection claim is unavailing.

*374 Accordingly, Puente’s petition for review is DENIED.
