34 U.S.C. § 20915 — Duration of registration requirement

(a) Full registration period. A sex offender must keep the registration current for the full registration period, not counting any time in custody or civil commitment — unless the offender qualifies for a reduction under subsection (b). The full period is: (1) 15 years for a tier I sex offender; (2) 25 years for a tier II sex offender; and (3) life for a tier III sex offender. (b) Reduced period for clean record. (1) Clean record. The full period gets reduced, as described in paragraph (3), for an offender who keeps a clean record for the period in paragraph (2) by: (A) not being convicted of any offense punishable by more than 1 year in prison; (B) not being convicted of any sex offense; (C) successfully completing any supervised release, probation, and parole; and (D) successfully completing a sex offender treatment program certified by a jurisdiction or by the Attorney General. (2) Period. (A) For a tier I sex offender, the clean record must be kept for 10 years. (B) For a tier III sex offender who was adjudicated delinquent as a juvenile for the offense requiring registration, the clean record must be kept for 25 years. (3) Reduction. (A) For a tier I sex offender, the reduction is 5 years off the 15-year period. (B) For a tier III sex offender adjudicated delinquent as a juvenile, the reduction is from a life requirement down to whatever period the clean record under paragraph (2) was maintained.
