The Fulbright Program, the flagship international educational exchange program sponsored by the U.S. government, is designed to increase mutual understanding between the people of the United States and the people of other countries. The Fulbright Program offers grants to study, teach and conduct research for U.S. citizens to go abroad and for non-U.S. citizens to come to the United States. The primary source of funding is an annual appropriation by the U.S. Congress to the U.S. Department of State's Bureau of Educational and Cultural Affairs (ECA). Participating governments and host institutions, as well as corporations and foundations in foreign countries and in the United States also provide direct and indirect support.
