Open Doors is the only long-standing, comprehensive information resource on international students and scholars in the United States and American students studying abroad for academic credit. Open Doors features graphic displays, data tables and policy-oriented analysis and is the essential resource for those concerned with U.S. international educational exchange. The Institute of International Education (IIE), the largest and most experienced U.S. higher education exchange agency, has conducted an annual statistical survey of international exchange activity in the United States, published as the Open Doors Report on International Educational Exchange, since 1948, with support from the Bureau of Educational and Cultural Affairs of the U.S. Department of State since 1972. The Open Doors 2009 report contains detailed information on the 671,616 international students in the U.S. in 2008/09, including national origin, field of study, institutional type, finances and personal characteristics; on the 262,416 U.S. students who studied abroad for academic credit in 2007/08; on the 113,494 international scholars who taught and conducted research at U.S. colleges and universities in 2008/09 and on the 54,487 international students enrolled in intensive English programs in the U.S. in 2008. Open Doors data tables are also available online at http://opendoors.iienetwork.org/, where you will find additional features not contained in this report.
