China is now sending more college students to study in the United States than any other country.  A new report shows a 23 percent increase in the number of Chinese students coming to the U.S.

The latest edition of the annual Institute of International Education(IIE)and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.

Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.

Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.

Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.

The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
