OPINION

Appellants are federal inmates who are or were confined at the Federal Correctional Institution in Loretto within the Western District of Pennsylvania. Each appellant is serving a sentence imposed outside that district, 1 and each appellant *20 filed a materially identical habeas petition under 28 U.S.C. § 2241 in that district seeking immediate release from prison. The District Court denied the petitions on April 16, 2014. Appellants appeal, and we will affirm. 2

Federal inmates may challenge the execution of their sentences under § 2241 in their court of confinement, see Burkey, 556 F.3d at 146, but they generally may challenge the legality of their sentences only under 28 U.S.C. § 2255 and must do so in the sentencing court, see United States v. Tyler, 732 F.3d 241, 246 (3d Cir. 2013); Furnari v. U.S. Parole Comm’n, 531 F.3d 241, 254 (3d Cir. 2008). Appellants in these cases requested immediate release from prison on the ground that their sentences are unlawful.

According to appellants, the Sentencing Reform Act of 1984 does not authorize incarceration unless the Bureau of Prisons (“BOP”) provides a mechanism for requesting a reduction in sentence for non-medical reasons under 18 U.S.C. § 3582(c)(1)(A)(i). 3 Appellants further contend that the BOP failed to provide them with a “compassionate release request packet” upon request and that, when they created and submitted their own, the BOP took no action on them.

Appellants, however, do not request an order directing the BOP to process any such request or to execute their sentences differently in any other way. Instead, they claim that the BOP’s alleged failure to process their requests for reduced sentences renders the sentences themselves unlawful and that “immediate release [from prison] is the only sanctioned remedy[.]” (E.g., W.D. Pa. Civ. No. 3-13-cv-00285, EOF No. 1-3 at 6.) To that end, each appellant “seeks the re-ordering of his sentence to provide that he serve his supervised release term immediately[.]” (E.g., id., ECF No. 1-1 at 4.)

The District Court properly recognized that it lacks jurisdiction to grant that request, which must be addressed to the courts that imposed the sentences that appellants seek to have “re-ordered.” No appellant has stated any reason why a § 2255 motion in his sentencing court might be “inadequate or ineffective to test the legality of his detention,” 28 U.S.C. § 2255(e), and we perceive none. Indeed, four appellants already have raised their claims in this regard before their sentenc *21 ing courts. 4 We thus express no opinion on the merits of appellants’ claims, though we note that appellants have not cited, and we are not aware of, any authority suggesting that their allegations state a basis for the relief they request, in their sentencing courts or any other.

For these reasons, appellees’ motion for summary action is granted and we will affirm the judgments of the District Court. Appellants’ pending motions in this Court are denied.
