A foreign banking corporation may, unless otherwise advised by the superintendent, obtain a license to establish a regional administrative office in this State with 45 days prior written notice to the superintendent. If a foreign banking corporation maintaining a licensed branch, agency, article XII investment company or bank in this State is performing a regional administrative office function on the same or contiguous premises as the licensed or chartered entity of the foreign banking corporation, the foreign banking corporation shall provide written notice to the superintendent of such fact and the particular regional administrative office functions performed and shall identify relevant regional office personnel. No separate license for those regional administrative office functions will be issued, unless the regional administrative office functions are either held out by the foreign banking corporation or determined by the superintendent to be separate from the other functions taking place on the premises. The foreign banking corporation shall notify the superintendent within 45 days of any change in regional administrative functions or personnel.
