The number of international students at US institutions rose 3% to a record high of 690,923 in the 2009–10 academic year, with gains in engineering, maths and computer science, says a report from the Institute of International Education, a New York-based non-profit organization. The report, out on 15 November, found that the growth was driven by a 30% increase in the number of students from China, who now represent some 18% of international enrolment. The report found that 18% of overseas students are pursuing engineering, up 7%; 9% are in biological and physical sciences, down slightly; and 9% are studying maths and computer science, up almost 8%. Stronger recruiting efforts helped to promote the increases, but visa woes contributed to fewer students coming from some nations.
