N.H. Rev. Stat. § 420-A:29
Any corporation organized under the laws of another state or country which except as to state of organization is a health service corporation and which the commissioner finds has fully complied with the laws of such other state or country, shall be entitled to do business within this state subject to this chapter after obtaining a license as provided in RSA 420-A:4; provided, however, that no such corporation organized under the laws of another state or country shall be entitled to such license, or to do business in this state, unless such other state or country grants substantially similar rights and privileges to health service corporations organized under the laws of this state. The commissioner shall determine whether rights and privileges granted by other states or countries are substantially similar to those granted by this state, and the commissioner's determination shall be final.
