Following remand, Julian Okeayainneh directly appeals the amended judgment entered by the district court, 1 resentencing him to a below-Guidelines-range prison term of 27 years. His counsel has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and Okeayainneh has filed a pro se supplemental brief, arguing that his conviction should be vacated on various grounds.

To begin, we decline to consider Okeaya-inneh’s arguments for vacating his conviction because they are beyond the scope of the remand. See United States v. Kendall, 475 F.3d 961, 963-64 (8th Cir. 2007) (scope of remand must be determined by reference to analysis in appellate court’s opinion; all issues decided by appellate court become law of case).

We conclude that the district court followed our instructions on remand by removing the 2-level obstruction-of-justice enhancement from Okeayainneh’s Guidelines calculations, which ultimately resulted in a total offense level of 43. See U.S.S.G. Ch. 5, Pt. A (sentencing table), comment, (n.2) (offense level of more than 43 is to be treated as offense level of 43). We further conclude that Okeayainneh’s 27-year prison term is substantively reasonable. See United States v. McCauley, 715 F.3d 1119, 1127 (8th Cir. 2013) (noting that when district court has varied below Guidelines range, “it is nearly inconceivable that the court abused its discretion in not varying downward still further” (quotation omitted)). In addition, we have independently reviewed the record under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), and have found no nonfrivolous issues for appeal. Accordingly, we affirm.
