22 U.S. Code § 254c - Extension of more favorable or less favorable treatment than provided under Vienna Convention; authority of President
The President may, on the basis of reciprocity and under such terms and conditions as he may determine, specify privileges and immunities for the mission, the members of the mission, their families, and the diplomatic couriers which result in more favorable treatment or less favorable treatment than is provided under the Vienna Convention.
1982—Pub. L. 97–241 substituted “immunities for the mission, the members” for “immunities for members” and “diplomatic couriers which” for “diplomatic couriers of any sending state which”.
By the authority vested in me as President of the United States of America by the Diplomatic Relations Act (Public Law 95–393, 92 Stat. 808; 22 U.S.C. 254a et seq.) and Section 301 of Title 3 of the United States Code, in order to implement the liability insurance and other requirements relating to diplomatic personnel, I hereby designate and empower the Secretary of State to perform, without the approval, ratification, or other action of the President, the functions vested or to be vested in the President by Section 4 of Diplomatic Relations Act (92 Stat. 809; 22 U.S.C. 254c).
