8 CFR 1215.2 - Authority of departure-control officer to prevent alien's departure from the United States.
(a) No alien shall depart, or attempt to depart, from the United States if his departure would be prejudicial to the interests of the United States under the provisions of § 1215.3. Any departure-control officer who knows or has reason to believe that the case of an alien in the United States comes within the provisions of § 1215.3 shall temporarily prevent the departure of such alien from the United States and shall serve him with a written temporary order directing him not to depart, or attempt to depart, from the United States until notified of the revocation of the order.
(b) The written order temporarily preventing an alien, other than an enemy alien, from departing from the United States shall become final 15 days after the date of service thereof upon the alien, unless prior thereto the alien requests a hearing as hereinafter provided. At such time as the alien is served with an order temporarily preventing his departure from the United States, he shall be notified in writing concerning the provisions of this paragraph, and shall be advised of his right to request a hearing if entitled thereto under § 1215.4. In the case of an enemy alien, the written order preventing departure shall become final on the date of its service upon the alien.
(c) Any alien who seeks to depart from the United States may be required, in the discretion of the departure-control officer, to be examined under oath and to submit for official inspection all documents, articles, and other property in his possession which are being removed from the United States upon, or in connection with, the alien's departure. The departure-control officer may permit certain other persons, including officials of the Department of State and interpreters, to participate in such examination or inspection and may exclude from presence at such examination or inspection any person whose presence would not further the objectives of such examination or inspection. The departure-control officer shall temporarily prevent the departure of any alien who refuses to submit to such examination or inspection, and may, if necessary to the enforcement of this requirement, take possession of the alien's passport or other travel document.
