In addition to the restrictions and prohibitions imposed by the provisions of this part upon the departure of aliens from the United States, any alien who seeks to depart from the Canal Zone, the Trust Territory of the Pacific Islands, or an outlying possession of the United States shall comply with such other restrictions and prohibitions as may be imposed by regulations prescribed, with the concurrence of the Administrator of the Bureau of Security and Consular Affairs and the Commissioner, by the Governor of the Canal Zone, the High Commissioner of the Trust Territory of the Pacific Islands, or by the governor of an outlying possession of the United States, respectively. No alien shall be prevented from departing from such zone, territory, or possession without first being accorded a hearing as provided in §§ 215.4 and 215.5.

The Governor of the Canal Zone, the High Commissioner of the Trust Territory of the Pacific Islands, or the governor of any outlying possession of the United States shall have the authority to designate any employee or class of employees of the United States as hearing officers for the purpose of conducting the hearing referred to in paragraph (a) of this section. The hearing officer so designated shall exercise the same powers, duties, and functions as are conferred upon special inquiry officers under the provisions of this part. The chief executive officer of such zone, territory, or possession shall, in lieu of the regional commissioner, review the recommended decision of the hearing officer, and shall render a decision in any case referred to him, basing it on evidence in the record and on any evidence or information of a confidential or a security nature which he deems pertinent.
