"New Jersey Laken Riley Act;" establishes law enforcement procedures for arrests of aliens unlawfully present in the U.S. charged with certain crimes.

The New Jersey Laken Riley Act requires law enforcement to check the immigration status of non-citizens arrested for specific serious crimes (including violent offenses, aggravated felonies, or motor vehicle crimes causing injury) using federal immigration databases. If confirmed as unlawfully present in the U.S., these individuals must be held in pretrial detention unless the prosecutor proves otherwise, overriding New Jersey’s bail reform laws. The bill also mandates compliance with federal immigration detainer requests and repeals prior state policies restricting cooperation with federal immigration enforcement. It directly affects non-citizens facing certain criminal charges and local law enforcement agencies handling their cases.
