The Lychner Act imposed two major obligations on the FBI that became effective October 3, 1997: Under the Act, the FBI may release relevant information to federal, state, and local criminal justice agencies for law enforcement purposes only.
Public notification will only be made if it is necessary to protect the public.
However, the Act specifically states that in no case shall the FBI release the identity of any victim of an offense that required registration of a sex offender.
The legislation also made it a criminal offense for a registered sex offender to move to another state and knowingly fail to notify the FBI and authorities in the new state.
Notification to the FBI and state authorities must be made within 10 days upon moving to a new state and/or establishing residence following release from prison or placed on parole, supervised release, or probation.
