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.
