Bill Overview

Analyzed Economic Effects

3 provisions identified: 1 benefits, 1 costs, 1 mixed.

Protections for crime victims and witnesses

Beginning January 1, 2026, the law protects crime victims and witnesses. Police do not have to share immigration information about a victim or witness who cooperates in good faith and on time. Agencies cannot detain someone only because they reported or witnessed a crime. People who are needed witnesses or victims of serious crimes like domestic violence, rape, or human trafficking are excluded from these cooperation rules.

Attorney General can sue to stop sanctuary policies

Beginning January 1, 2026, the Attorney General may sue state or local officers or agencies that violate this law. Courts must block unlawful sanctuary policies and can keep enforcing orders, including through contempt. Any injunction or consent decree must include written findings that describe the policy.

New Hampshire bans sanctuary policies, expands cooperation

Beginning January 1, 2026, New Hampshire bans state and local “sanctuary” policies. Police and jails must use their best efforts to work with federal immigration agencies. Agencies may send, request, keep, and share a person’s immigration‑status information, unless federal law bars it. A detainer must show probable cause and include a federal warrant form (I‑200 or I‑205, or a successor). The law defines sanctuary policies to include blocking detainers, release notices, interviews, or 287(g) participation.
