Establishes law enforcement procedures for responding to immigration detainers and certain requests issued by federal immigration authorities.

This bill (A 3267) requires New Jersey law enforcement agencies and correctional facilities to refuse federal immigration detainer requests unless the person has been convicted of specific serious crimes, such as murder, sexual assault, domestic violence, or terrorism. It prohibits agencies from detaining, transferring, or notifying federal authorities about a person solely based on immigration requests unless one of these 21 offenses applies. The bill does not prevent agencies from sharing immigration status information with other government entities under existing federal law (8 U.S.C. 1373). It aligns with court rulings confirming states are not obligated to comply with immigration detainers and mirrors California’s "Trust Act" approach. The law takes effect immediately upon enactment.
