22 U.S. Code § 4315 - Use of foreign mission in manner incompatible with its status as foreign mission
A foreign mission may not allow an unaffiliated alien the use of any premise of that foreign mission which is inviolable under United States law (including any treaty) for any purpose which is incompatible with its status as a foreign mission, including use as a residence.
For the purposes of this section, the term “residence” does not include such temporary lodging as may be permitted under regulations issued by the Secretary.
The Secretary may waive subsection (a) with respect to all foreign missions of a country (and may revoke such a waiver) 30 days after providing written notification of such a waiver, together with the reasons for such waiver (or revocation of such a waiver), to the Committee on Foreign Affairs of the House of Representatives and the Committee on Foreign Relations of the Senate.
Not later than 180 days after December 22, 1987, the Secretary of State shall submit a report to the Congress concerning the implementation of this section and shall submit such other reports to the Congress concerning changes in implementation as may be necessary.
December 22, 1987, referred to in subsec. (d), was in the original “the date of the enactment of this Act”, which was translated as meaning the date of enactment of Pub. L. 100–204, which enacted this section, to reflect the probable intent of Congress.
