Under the terms of a written plea agreement, Jose Carreon pleaded guilty to conspiring to distribute cocaine, in violation of 21 U.S.C. § 841(a)(1), (B)(1)(A), and § 846; and entering the United States unlawfully as an alien, in violation of 8 U.S.C. § 1325(a). The district court 1 determined that Mr. Carreon was entitled to 18 U.S.C. § 3553® relief from the statutory minimum sentence for the drug offense, and imposed a sentence of 63 months in prison and 3 years of supervised release. His counsel has moved to withdraw and filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), questioning whether the sentence was reasonable.

We see no indication that the district court erred in applying the advisory Sentencing Guidelines, considering the rele *607 vant sentencing factors, or explaining its sentence; and we conclude that the sentence, at the bottom of the undisputed Guidelines range, was not unreasonable. See United States v. Hull, 646 F.3d 583, 588 (8th Cir. 2011) (reviewing sentence under deferential abuse-of-discretion standard; according presumption of reasonableness to sentence within advisory Guidelines range); United States v. Feemster, 572 F.3d 455, 461 (8th Cir. 2009) (en banc) (describing procedural error). Having reviewed the record independently under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfrivolous issue. Accordingly, we affirm the judgment of the district court and we grant counsel’s motion to withdraw, subject to counsel informing Mr. Carreon about procedures for seeking rehearing or filing a petition for certiorari.
