Grad Student Ambassadors

U.S. higher education is an export industry, with positive externalities:

one of the best ways the United States can improve its image abroad is to encourage more foreigners to spend a year or two in America. It is therefore heartening to see that, according to the Council on Graduate Schools, there has been a recovery in international students attending U.S. graduate schools: "First-time enrollment increased by 4% in 2005, the first increase in four years."
