Affirmed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Appellant Jose Daniel Cardenas-Covarrubias appeals his forty-six month sentence imposed after his guilty plea to unlawful reentry of a deported alien, in violation of 8 U.S.C. § 1326 (2006). Cardenas-Covarrubias’ sole argument on appeal is that the district court erred in calculating his Guidelines sentencing range when it increased his offense level by sixteen levels pursuant to U.S. Sentencing Guidelines Manual (USSG) § 2L1.2 (b)(l)(A)(ii) (2009).

Cardenas-Covarrubias correctly concedes that his argument is foreclosed by our decision in United States v. DiazIbarra, 522 F.3d 343, 352-53 (4th Cir. 2008) (holding that “[sjexual abuse of a minor”— which is listed as a “crime of violence” in USSG § 2L1.2 cmt. n. l(b)(iii) — need not be a crime that requires the use, or threatened use, of physical force against another, but must be a crime that prohibits the “physical or nonphysical misuse or maltreatment of a minor for a purpose associated with sexual gratification”). We may *770 not overrule this court’s binding precedent. United States v. Simms, 441 F.3d 313, 318 (4th Cir. 2006) (“A decision of a panel of this court becomes the law of the circuit and is binding on other panels unless it is overruled by a subsequent en banc opinion of this court or a superseding contrary decision of the Supreme Court.” (internal quotation marks and citation omitted)).

Accordingly, we affirm the judgment of the district court. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED.
