(a) (1) No foreign (other nation) credit union that is licensed to maintain a representative office shall close the office unless the commissioner shall have first approved the closing. (2) Paragraph (1) shall not be deemed to prohibit a foreign (other nation) credit union that is licensed to maintain a representative office from closing the office in accordance with Article 8 (commencing with Section 16800). (b) If the commissioner finds, with respect to an application by a foreign (other nation) credit union for approval to close a representative office, that the closing of the office will not be substantially detrimental to the public convenience and advantage, the commissioner shall approve the application. If the commissioner finds otherwise, the commissioner shall deny the application. (c) Whenever an application by a foreign (other nation) credit union for approval to close a representative office has been approved and all conditions precedent to the closing have been fulfilled, the foreign (other nation) credit union may close the office and shall promptly thereafter surrender to the commissioner the license that authorized it to maintain the office.
