N.Y. Comp. Codes R. & Regs. tit. 3, § 66.3
(a) Subject to the provisions of this Part, an out-of-state savings and loan holding company or subsidiary thereof may acquire control, directly or indirectly, of one or more insured institutions; provided, however, that no such acquisition of control shall be lawful without the prior approval of the superintendent.
