MEMORANDUM**

Jose Sevilla-Mancilla appeals the 33-month sentence imposed following his guilty plea to being a deported alien found in the United States in violation of 8 U.S.C. § 1326. Sevilla-Mancilla contends that the district court improperly applied a sixteen-level upward adjustment under U.S.S.G. § 2L1.2(b)(l)(A) based on prior convictions that were obtained in violation of his Sixth Amendment right to effective assistance of counsel and while he was incompetent.

We affirm because Sevilla-Mancilla is not entitled to collaterally attack his prior convictions on these grounds. Custis v. United States, 511 U.S. 485, 114 S.Ct. 1732, 128 L.Ed.2d 517 (1994) (holding that the Constitution requires only that collateral attacks be allowed against predicate convictions obtained in violation of the right to appointed counsel, and that ineffective assistance of counsel does not rise to the level of the jurisdictional defect resulting from the failure to appoint counsel); United States v. Martinez-Martinez, 295 F.3d 1041, 1043-45 (9th Cir. 2002) (holding in a § 1326 case that collateral attacks on prior state convictions at sen*801tencing are prohibited); United, States v. Gutierrez-Cervantez, 132 F.3d 460, 462 (9th Cir. 1997) (applying Custis to preclude collateral attacks on prior state convictions in § 1326 proceedings).

AFFIRMED.
