Edgar Lara-Garcia pleaded guilty to illegal reentry after deportation. See 8 U.S.C. § 1326(a) and (b)(2). The district court 1 sentenced him to 18 months in prison and 3 years of supervised release. On appeal, 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), asserting that the sentence was unreasonable.

*903 We conclude the district court did not impose an unreasonable sentence: the court committed no significant procedural error in sentencing Lara-Garcia, see United States v. Feemster, 572 F.3d 455, 461 (8th Cir. 2009) (en banc) (describing procedural error); and Lara-Garcia has not rebutted the presumption that his sentence, at the bottom of the undisputed Guidelines range, was substantively reasonable, see United States v. Hull, 646 F.3d 583, 588 (8th Cir. 2011) (sentence within advisory Guidelines range is presumed reasonable). 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 grant counsel’s motion to withdraw, and we affirm.
