Students from the top three places of origin -- China, India, and South Korea -- now represent approximately 50 percent of the total enrollment of international students in the U.S., with the number from China and India increasing, and the numbers from South Korea declining.

Each of the top 25 places of origin had 5,000 or more students in the US. There were increases in the number of students from 17 of the top 25 places of origin, including Brazil, Canada, China, Colombia, Germany, Hong Kong, India, Indonesia, Iran, Kuwait, Mexico, Nigeria, Saudi Arabia, Spain, Britain, Venezuela, and Vietnam.

The report also found that more American students -- a total of 289,408 -- studied abroad.

There were declines in the number of American students going to China, Australia, Argentina, India, Mexico, Ecuador, Israel, Chile, and New Zealand.

The U.S. hosts more of the world's 4.5 million globally mobile college and university students than any other country in the world, with almost double the number hosted by Britain, the second leading host country, according to the report.

International students' spending in all 50 states contributed more than $27 billion to the US economy in 2013, according to the U.S. Department of Commerce.
