Section 1116(b)(2) of title 18 of the United States Code, as added by Pub. L. 92-539, An Act for the Protection of Foreign Officials and Official Guests of the United States (86 Stat. 1071), defines the term “foreign official” for purposes of that Act as “any person of a foreign nationality who is duly notified to the United States as an officer or employee of a foreign government or international organization, and who is in the United States on official business, and any member of his family whose presence in the United States is in connection with the presence of such officer or employee.” Section 1116(c)(4) of the same Act defines the term “official guest” for the purposes of that Act as “a citizen or national of a foreign country present in the United States as an official guest of the Government of the United States pursuant to designation as such by the Secretary of State.” It is the purpose of this regulation to specify the officer of the Department of State who shall be responsible for receiving notification of foreign officials under the Act and determining whether persons are “duly notified” to the United States and who shall be responsible for processing official guest designations by the Secretary of State.

(a) Any notification of a foreign official for purposes of section 1116(b)(2) of Title 18 of the United States Code shall be directed by the foreign government or international organization concerned to the Chief of Protocol, Department of State, Washington, DC 20520. For persons normally accredited to the United States in diplomatic or consular capacities and also for persons normally accredited to the United Nations and other international organizations and in turn notified to the Department of State, the procedure for placing a person in the statutory category of being “duly notified to the United States” shall be the current procedure for accreditation, with notification in turn when applicable. The Chief of the Office of Protocol will place on the roster of persons “duly notified to the United States” the names of all persons currently accredited and, when applicable, notified in turn, and will maintain the roster as part of the official files of the Department of State adding to and deleting therefrom as changes in accreditations occur.

(b) For those persons not normally accredited, the Chief of Protocol shall determine upon receipt of notification, by letter from the foreign government or international organization concerned, whether any person who is the subject of such a notification has been duly notified under the Act. Any inquiries by law enforcement officers or other persons as to whether a person has been duly notified shall be directed to the Chief of Protocol. The determination of the Chief of Protocol that a person has been duly notified is final.

The Chief of Protocol shall also maintain a roster of persons designated by the Secretary of State as official guests. Any inquiries by law enforcement officers or other persons as to whether a person has been so designated shall be directed to the Chief of Protocol. The designation of a person as an official guest is final. Pursuant to section 2658 of title 22 of the U.S.C., the authority of the Secretary of State to perform the function of designation of official guests is hereby delegated to the Chief of Protocol.

The Chief of Protocol shall maintain as a part of the official files of the Department of State a cumulative roster of all persons who have been duly notified as foreign officials or designated as official guests under this part. The roster will reflect the name, position, nationality, and foreign government or international organization concerned or purpose of visit as an official guest and reflect the date the person was accorded recognition as being “duly notified to the United States” or designated as an official guest and the date, if any, of termination of such status.
