On May 22, 2025, Governor Kelly Ayotte signed House Bill 511 and Senate Bill 62 to ban sanctuary cities and support cooperation between state and local law enforcement and federal immigration authorities.

Governor Ayotte released the following statement after signing both bills into law:

“I said from the beginning that we won’t let our state go the way of Massachusetts and their billion-dollar illegal immigrant crisis. Today, we’re delivering on our promise by banning sanctuary cities and supporting law enforcement cooperation with federal immigration authorities. New Hampshire will never be a sanctuary for criminals, and we will keep working every day to remain the safest state in the nation.”
