No, New Hampshire has no legislation regulating the carry of a firearm on campus property, leaving the regulation up to the individual college.
Students should seek changes within their school policy to allow for the carry of a firearm, or contact state officials in hopes that legislative change could be made to require the right to carry a firearm on campus to be legally enforced.
Students could face trespassing charges or repercussions depending on the policy of the University.
New Hampshire Revised Statutes Chapter 159 on firearm regulations has no sections preventing a school’s ability to permit students to carry a firearm, therefore the school should simply change there policy to allow for students to carry.
