In the event such certificates or statements are received in evidence, the alien may request and, in the discretion of the special inquiry officer, be given an opportunity to interrogate such officials or persons, by deposition or otherwise, at a time and place and in a manner fixed by the special inquiry officer: Provided, That when in the judgment of the special inquiry officer any evidence relative to the disposition of the case is of a confidential or security nature the disclosure of which would be prejudicial to the interests of the United States, such evidence shall not be presented at the hearing but shall be taken into consideration in arriving at a decision in the case.

(5) The alien may present such additional evidence, including the testimony of witnesses, as is pertinent and available.

(b) A complete verbatim transcript of the hearing, except statements made off the record, shall be recorded. The alien shall be entitled, upon request, to the loan of a copy of the transcript, without cost, subject to reasonable conditions governing its use.

(c) Following the completion of the hearing, the special inquiry officer shall make and render a recommended decision in the case, which shall be governed by and based upon the evidence presented at the hearing and any evidence of a confidential or security nature which the Government may have in its possession. The decision of the special inquiry officer shall recommend (1) that the temporary order preventing the departure of the alien from the United States be made final, or (2) that the temporary order preventing the departure of the alien from the United States be revoked. This recommended decision of the special inquiry officer shall be made in writing and shall set forth the officer's reasons for such decision. The alien concerned shall at his request be furnished a copy of the recommended decision of the special inquiry officer, and shall be allowed a reasonable time, not to exceed 10 days, in which to submit representations with respect thereto in writing.

(d) As soon as practicable after the completion of the hearing and the rendering of a decision by the special inquiry officer, the district director shall forward the entire record of the case, including the recommended decision of the special inquiry officer and any written representations submitted by the alien, to the regional commissioner having jurisdiction over his district. After reviewing the record, the regional commissioner shall render a decision in the case, which shall be based upon the evidence in the record and on any evidence or information of a confidential or security nature which he deems pertinent. Whenever any decision is based in whole or in part on confidential or security information not included in the record, the decision shall state that such information was considered. A copy of the regional commissioner's decision shall be furnished the alien, or his attorney or representative. No administrative appeal shall lie from the regional commissioner's decision.

(e) Notwithstanding any other provision of this part, the Administrator of the Bureau of Security and Consular Affairs referred to in section 104(b) of the Immigration and Nationality Act, or such other officers of the Department of State as he may designate, after consultation with the Commissioner, or such other officers of the Immigration and Naturalization Service as he may designate, may at any time permit the departure of an individual alien or of a group of aliens from the United States if he determines that such action would be in the national interest. If the Administrator specifically requests the Commissioner to prevent the departure of a particular alien or of a group of aliens, the Commissioner shall not permit the departure of such alien or aliens until he has consulted with the Administrator.

(f) In any case arising under §§ 46.1 to 46.7, the Administrator shall, at his request, be kept advised, in as much detail as he may indicate is necessary, of the facts and of any action taken or proposed.

No alien shall be prevented from departing from such zone, territory, or possession without first being accorded a hearing as provided in §§ 46.4 and 46.5.

(b) 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.

In the absence of appropriate instructions from the Administrator of the Bureau of Security and Consular Affairs, departure-control officers shall not exercise the authority conferred by § 46.2 in the case of any alien who seeks to depart from the United States in the status of a nonimmigrant under section 101(a)(15) (A) or (G) of the Immigration and Nationality Act, or in the status of a nonimmigrant under section 11(3), 11 (4), or 11(5) of the Agreement between the United Nations and the United States of America regarding the Headquarters of the United Nations (61 Stat. 756): Provided, That in cases of extreme urgency, where the national security so requires, a departure-control officer may preliminarily exercise the authority conferred by § 46.2 pending the outcome of consultation with the Administrator, which shall be undertaken immediately. In all cases arising under this section, the decision of the Administrator shall be controlling: Provided, That any decision to prevent the departure of an alien shall be based upon a hearing and record as prescribed in this part.
