N.Y. Banking Law § 28
Upon receipt by the superintendent of a written application in proper form from any banking organization or foreign corporation for leave to change its place or one of its places of business to another place or from any banking organization for leave to change the designation of its principal office to a branch office and to change the designation of one of its branch offices to its principal office, the superintendent shall, if he or she shall be satisfied that such change may be permitted under the terms of this chapter and that there is no reasonable objection to such change, execute and issue a certificate under the official seal of the department authorizing such change and specifying the date on or after which such change may be made, and shall cause the original of such certificate to be transmitted to the applicant, a copy to be filed in the office of the department and a copy to be filed in the office of the clerk of the county in which the principal office of the applicant is located, provided that if the proposed principal office is in a different county than the county in which the principal office is located at the time of the filing of the application, the superintendent shall cause copies to be filed in the offices of the clerks of both counties. If the superintendent shall be satisfied in any case that such change is undesirable or inexpedient, he or she shall refuse such application and notify the applicant of such determination.
