Sebastian Beltran-Bueno pleaded guilty to illegal reentry following deportation, in violation of 8 U.S.C. § 1326(a) and (b)(2), and the district court 1 sentenced him to 41 *804 months of imprisonment and 3 years of supervised release. On appeal, counsel has moved to withdraw under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and has filed a brief arguing that the district court should have granted Beltran-Bueno’s motion for a downward departure because he agreed to be voluntarily deported.

The district court’s comments at sentencing indicate that its decision not to depart was purely discretionary, and therefore the decision is unreviewable on appeal. See United States v. Field, 110 F.3d 587, 591-92 (8th Cir. 1997).

Moreover, following our independent review, see Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfrivolous issues.

Accordingly, the judgment is affirmed. We also grant counsel’s motion to withdraw.
