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

New Jersey's Assembly Bill 1065 establishes rules for local law enforcement agencies and correctional facilities when responding to federal immigration requests. It prohibits police from detaining or transferring individuals based on immigration requests (like detainers or transfer forms) unless the person has been convicted of one of 21 specific serious crimes, including murder, aggravated assault, sexual assault, robbery, or domestic violence. The bill allows law enforcement to still share citizenship or immigration status information with federal authorities as permitted by federal law (8 U.S.C. 1373). It directly affects all state, county, and municipal police departments and jails in New Jersey. The law takes effect immediately upon passage.
