The U.S. Department of State's Bureau of Educational and Cultural Affairs (ECA) sponsors the Fulbright Program under policy guidelines established by the J. William Fulbright Foreign Scholarship Board (FSB) and in cooperation with bi-national Fulbright Commissions and the Public Affairs Sections of U.S. Embassies abroad. As the administrative and executive arm of the Fulbright Program, ECA has fiscal responsibility for the preparation of an annual budget request to Congress and makes decisions on funding allocations to participating countries. Under policies established by the FSB, ECA also holds primary responsibility for the administration of the program, together with the assistance of cooperating non-profit organizations. The U.S. Student Program grant numbers are subject to the availability of federally-appropriated funds. The United States Department of State reserves the right to alter, without notice, participating countries, numbers of awards, terms of agreement, and allowances.
