BEIJING, June 3 (Xinhua) -- China's Ministry of Education on Monday warned Chinese students and scholars of the risks of going to study in the United States citing U.S. visa restrictions, urging them to step up risk assessment and prepare accordingly.

The alert states that the visa applications of some Chinese hoping to study in the United States have recently been restricted, with an extended reviewing process, shortened validity period, and an increased rejection rate, which has affected their plans to study in the United States or the completion of their study there.
