The Federal Public Defender appointed to represent Jose Delapaz Escobar 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), and United States v. Flores, 632 F.3d 229 (5th Cir. 2011). Escobar has filed a response. To the extent that Escobar’s claims of ineffective assistance relate to his substantive sentencing claims concerning the 16-point sentencing enhancement under U.S.S.G. § 2L1.2(b)(1)(A)(ii) and the calculation of his criminal history points based on his prior sentences under § 4A1.1 and § 4A1.2, these claims present no nonfrivo-lous issue. See Clark v. Collins, 19 F.3d 959, 966 (5th Cir. 1994) (counsel does not render ineffective assistance by failing to make meritless objections). To the extent that Escobar’s claims of ineffective assistance of counsel go beyond that, the record is insufficiently developed to allow consideration at this time of Escobar’s claims; such claims generally “cannot be resolved on direct appeal when [they have] not been raised before the district court since no *391 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). We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Escobar’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Accordingly, the 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.
