After James C. Lewis pleaded guilty to being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g)(1), the district court 1 sentenced him to 33 months imprisonment and 3 years supervised release. Counsel has filed a brief and has moved to withdraw under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that Mr. Lewis should receive credit for time he spent in a county jail before being indicted on the instant offense. Mr. Lewis, however, must first exhaust his administrative remedies by presenting his claim to the Bureau of Prisons. See United States v. Chappel, 208 F.3d 1069, 1069-70 (8th Cir. 2000) (per curiam); 28 C.F.R. §§ 542.10-542.19 (2001). Having reviewed the record independently under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), and having found no nonfrivolous issues, we grant counsel’s motion to withdraw and affirm the judgment of the district court.
