Gonzalo Romero-Madera appeals from the within-Guidelines-range sentence that the District Court 1 imposed after he pleaded guilty to a drug offense. His counsel has moved to withdraw and has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), challenging the reasonableness of Romero-Madera’s sentence. After careful review, we conclude that the District Court did not impose an unreasonable sentence. See Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007) (describing appellate review of sentencing decisions and noting that if a sentence is within the Guidelines range, the court of appeals may apply a presumption of reasonableness). Further, having independently reviewed the record in accordance with Penson v. Ohio, 488 U.S. 75, 80, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we have found no nonfrivolous issues. We therefore affirm the judgment of the District Court, and we grant counsel’s motion to withdraw subject to counsel informing Romero-Madera about procedures for seeking rehearing or filing a petition for certiorari.
