Students around the globe are increasingly likely to study outside of their own country.
The number of students studying abroad rose from 800,000 in 1975 to 4.5 million in 2012, according to the Organization for Economic Cooperation and Development. "It's been doubling once a decade," says Peggy Blumenthal, senior counselor to the president at the Institute of International Education. "There are projections it will go up to 8 million in another 10 years."
