HB 511 requires local police to comply with immigration detainers and bans local government from adopting “sanctuary policies” that thwart federal immigration law. CPAC believes that this measure will help keep the citizens of New Hampshire safe, and it supports this bill. HB 511 passed the New Hampshire House of Representatives in a 211-161 vote on April 10, 2025, and it was later signed into law by Governor Kelly Ayotte.
