Timothy Daniels, federal prisoner #24703-009, appeals the district court’s dismissal of his 28 U.S.C. § 2241 petition. Relying on Descamps v. United States, — U.S. -, 133 S.Ct. 2276, 186 L.Ed.2d 438 (2013), and Moncrieffe v. Holder, — U.S. -, 133 S.Ct. 1678, 185 L.Ed.2d 727 (2013), Daniels argues that the district court erroneously determined that he was an armed career criminal pursuant to U.S.S.G. § 4B1.4(a), resulting in a higher advisory sentencing range under the Sentencing Guidelines.

*148 The district court determined that Daniels had not met the criteria for proceeding under the savings clause of 28 U.S.C. § 2255, which allows a federal prisoner to attack the legality of his conviction in a § 2241 petition if he can show that the remedies provided under § 2255 are “inadequate or ineffective to test the legality of his detention.” § 2255(e). The district court determined that because Daniels was raising a claim of sentencing error, his claim was outside the scope of § 2241.

A prisoner seeking to establish that his § 2255 remedy is inadequate or ineffective must make a claim (i) “based on a retroactively applicable Supreme Court decision which establishes that the petitioner may have been convicted of a nonexistent offense” that (ii) “was foreclosed.by circuit law at the time when the claim should have been raised in the petitioner’s trial, appeal, or first § 2255 motion.” Reyes-Requena v. United States, 243 F.3d 893, 904 (5th Cir. 2001). Neither Descamps nor Mon-crieffe has any effect on whether the facts of Daniels’s case would support his conviction for the substantive offense; therefore, neither is a retroactively applicable Supreme Court decision indicating that he was convicted of a nonexistent offense. See, e.g., Wesson v. U.S. Penitentiary Beaumont, TX, 305 F.3d 343, 348 (5th Cir. 2002). Moreover, claims relating to sentencing determinations do not fall within the savings clause and are not cognizable under § 2241, even where the petitioner asserts a “miscarriage of justice” or actual innocence relating to the alleged sentencing errors. See, e.g., Preston v. Ask-Carlson, 583 Fed.Appx. 462, 463 (5th Cir. 2014); Torres v. Young, 457 Fed.Appx. 427, 429 (5th Cir. 2012).

Accordingly, the judgment of the district court is AFFIRMED. Daniels’s motion to stay the proceedings is DENIED.
