Visa Question of the Day; On Two-Year Foreign Residency Requirement;
If the exchange student is sponsored by an international organisation does the person fit in this category?

Information provided is;

An exchange visitor is subject to INA 212(e) requirement, if the following conditions exist:
The program in which the exchange visitor was participating was financed in whole or in part directly or indirectly by the United States government or the government of the exchange visitor's nationality or last residence;
The exchange visitor is a national or resident of a country designated as requiring the services of persons engaged in the field of specialized knowledge or skills in which the exchange visitor was engaged for the duration of their program (Exchange Visitor Skills List 9 FAM 41.62, Exhibit II);
The exchange visitor entered the United States to receive graduate medical education or training.

My answer; Any student sponsored by an international organisation for which US provides funds will have to be covered under this rule.
