Prevent Repeat Offenders Act of 2015

Prevent Repeat Offenders Act of 2015 This bill amends the Sex Offender Registration and Notification Act to direct the Department of Homeland Security (DHS) to ensure that: (1) any alien who is required to register under such Act is registered in the National Sex Offender Registry and is informed of the registration requirements under such Act before such alien may be released from the custody of U.S. Immigration and Customs Enforcement (ICE), and (2) the release of such an alien is conditioned on such alien's registration in each jurisdiction required by such Act. DHS is also required to ensure that the chief law enforcement officer of each jurisdiction in which such an alien resides and the agency responsible for the receipt or maintenance of sex offender registration information in such jurisdiction are promptly notified when such an alien is: (1) taken into custody by ICE, (2) released from ICE custody, or (3) removed from the United States.
