Mass. Gen. Laws ch. 171 § 8C
A foreign credit union or out-of-state federal credit union, if such credit union does not operate a branch in the commonwealth, may establish and maintain a new branch in the commonwealth; provided, however, that the credit union submits an application in the manner and form prescribed by the commissioner and the commissioner approves that application; provided further, that the laws of the state in which the credit union has its principal place of business expressly authorize, under conditions not more restrictive than those imposed by this chapter as determined by the commissioner, a Massachusetts credit union to establish and maintain a branch therein. Any such foreign credit union or out-of-state federal credit union shall operate under the supervision of the commissioner and in accordance with all applicable laws governing Massachusetts credit unions, including all rules and regulations promulgated thereunder.
An out-of-state federal credit union shall operate the same as a federal branch which shall be subject to all laws of the commonwealth relative to community reinvestment, consumer protection, fair lending, establishment of intra-state branches, including but not limited to, sections 1 to 14A, inclusive, of chapter 93, and the applicable sections of chapters 93A, 167, 167B, 171, 183 and 184, including all rules and regulations promulgated thereunder and to such other laws of the commonwealth as are applicable to a federal credit union with its main office in the commonwealth.
