These exchanges are defined by section 102 of the Act, 22 U.S.C. 2452 , and section 101(a)(15)(J) of the Immigration and Nationality Act, as amended, 8 U.S.C. 1101(a)(15)(J) .(b) The Secretary of State of the Department of State facilitates activities specified in the Act, in part, by designating public and private entities to act as sponsors of the Exchange Visitor Program. Sponsors may act independently or with the assistance of third parties. The purpose of the Program is to provide foreign nationals with opportunities to participate in educational and cultural programs in the United States and return home to share their experiences, and to encourage Americans to participate in educational and cultural programs in other countries. Exchange visitors enter the United States on a J visa. The regulations set forth in this subpart are applicable to all sponsors.(c) The Assistant Secretary for Educational and Cultural Affairs of the Department of State may, in his or her sole discretion and to the extent consistent with the authorities described in paragraph (a) of this section and other applicable law, waive or modify any provision of this part with respect to programs that are established pursuant to memoranda of understanding, letters of intent or similar arrangements between the United States and foreign governments. When establishing such a program, the Department will publish a notice in the FEDERAL REGISTER describing the program and any resulting modifications to or waivers of provisions of this part. If such an arrangement will not result in a waiver of or other modification to the provisions of this part, then the Department need not publish a notice. 79 FR 60307 , Oct. 6, 2014
