In the federal system, how long does an offender wait to go back before a board if they are denied parole on a sentence shorter than seven years?

In the federal system, if an offender is denied parole on a sentence that is shorter than seven years, they must wait 18 months before being eligible to go before the parole board again. This waiting period allows for a re-evaluation of the offender's behavior while incarcerated and their potential for rehabilitation. The 18-month interval is designed to provide sufficient time for the offender to demonstrate progress or improvements in their conduct and readiness for reintegration into society. This standard reflects the federal system's approach to balancing accountability with opportunities for change and does not exceed the requirements stipulated for shorter sentences.
