The New Jersey Immigrant Trust Act is designed to enhance protections for immigrants by ensuring their safety and constitutional rights when interacting with government agencies, regardless of their immigration status. The bill asserts that the enforcement of federal immigration law is a federal responsibility and should not interfere with local public safety priorities. It prohibits state, county, and municipal law enforcement agencies from inquiring about an individual's immigration status or detaining individuals based on civil immigration warrants or detainers, which do not require probable cause. Additionally, the act restricts government entities and healthcare facilities from collecting immigration-related information unless strictly necessary for service eligibility assessments and establishes guidelines to maintain sensitive locations, such as schools and healthcare facilities, accessible to all residents.

The legislation also outlines a comprehensive framework for state and local government entities regarding their involvement with federal immigration enforcement. It prohibits these entities from assisting federal immigration authorities in various ways, including participating in civil immigration enforcement operations and sharing personal information about individuals. The bill nullifies any existing agreements that conflict with its provisions and requires law enforcement agencies to provide written explanations to individuals in custody if they intend to comply with immigration detainers. Furthermore, law enforcement agencies must report their interactions with immigration authorities to the Attorney General, who will publish these reports and ensure compliance. The act emphasizes the protection of personal information, mandates training for law enforcement, and promotes public awareness campaigns to inform immigrant communities about their rights, ultimately aiming to create a more protective environment for immigrants in New Jersey.
