The Federal Public Defender appointed to represent Ramon Sanchez-Rosas has moved for leave to withdraw and has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Sanchez-Rosas has filed a response, in which he makes a request for appointment of new counsel. The record is insufficiently developed to allow consideration at this time of Sanchez-Rosas’s claim of ineffective assistance of counsel; such a claim generally “cannot be resolved on direct appeal when the claim has not been raised before the district court since no opportunity existed to develop the record on the merits of the allegations.” United States v. Cantwell, 470 F.3d 1087, 1091 (5th Cir. 2006) (internal quotation marks and citation omitted). Our independent review of the record, counsel’s brief, and Sanchez-Rosas’s response discloses no nonfrivolous issue for appeal. Accordingly, counsel’s motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th CiR. R. 42.2. Sanchez-Rosas’s motion for appointment of new counsel is DENIED. Cf. United States v. Wagner, 158 F.3d 901, 902-03 (5th Cir. 1998).
