A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001.

American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa (签证) requirements. Now stronger efforts are being made to get more foreign students to study in the United States.

China remained in second place in front of South Korea but behind India, which sent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place.

There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand.

For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University.

Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering.

The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year.
