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 bill also outlines a comprehensive framework for state and local government entities regarding their interactions with federal immigration authorities, prohibiting cooperation with immigration enforcement in various forms, including sharing personal information and participating in civil immigration operations. Any conflicting existing agreements or practices will be voided upon enactment. Law enforcement agencies are required to provide written explanations to individuals in custody if they intend to comply with immigration detainers and must submit detailed reports to the Attorney General about their interactions with immigration authorities. The Attorney General will publish this information and ensure compliance through regulations, while also mandating training for law enforcement and the development of model policies for sensitive locations to encourage eligible individuals to seek services without fear of deportation or discrimination.
