Detainer
A hold another agency (ICE, a state court, another jurisdiction) lodges against a person in BOP custody, asking to take custody at release. Active detainers generally block halfway-house and home-confinement placement, and a final order of removal — but not a mere ICE detainer — blocks applying FSA credits.

Estimates, not promises
This page describes federal law and Bureau of Prisons policy in general terms for education. It is not legal advice, it doesn't account for the facts of any individual case, and no attorney–client relationship is created by reading it. The BOP makes all final release-date determinations. Have an attorney review anything before you file it. Built by OutDate, the federal release date calculator.
