Hundreds of thousands of Chinese students are flocking to US colleges and universities, helping to push the number of international students studying in America to record levels.
The number of American students studying abroad also has hit an all-time high.
The findings are in an analysis being released Monday that was conducted by a nonprofit group that worked with the US State Department.
Foreign students contribute about $24 billion annually to the US economy, and about two-thirds of them primarily pay their own way or their families do, according to the Institute of International Education and the State Department's Bureau of Educational and Cultural Affairs.
All told, 819,644 students came to the United States to study abroad in the 2012-13 school year. The highest numbers were from China, India, South Korea, Saudi Arabia and Canada. That's a record high, up 7 percent from a year earlier and 40 percent from more than a decade ago.
Despite the increases, international students make up less than 4 percent of all students.
About 235,000 of the international students were from China, a 21 percent increase. A burgeoning middle class in China was cited as a factor. About one-third studied business and management once they arrived, the report said.
“Chinese students and their parents are looking for high-quality education, get the importance of international education, and it's making America the No. 1 destination because we actually have the capacity to absorb international students,'' said Allan Goodman, president and CEO of the institute.
The number of students from Saudi Arabia studying in the United States jumped 30 percent, to 45,000. These students are largely funded by a Saudi government scholarship program nearly in its 10th year, the report said.
By contrast, 283,332 U.S. students studied abroad for academic credit _ a 3 percent increase from a year earlier.
In the past 20 years, the number of U.S. students studying abroad has tripled. But less than 10 percent of American students study abroad during their college years. The United Kingdom, Italy, Spain, France and China were the top destinations.
