The Department of Homeland Security has ordered new security checks for all foreign students entering the United States.
Aside from standard verification of their travel documents, arriving students now will also be checked through a database known as the Student and Exchange Visitor Information System, officials said. The system contains information on schools with foreign students and on the students’ enrollment status.
Students generally are allowed a 30-day grace period to re-establish enrollment before they are required to leave. But the leeway applies only to students remaining in the country; those who fail to maintain enrollment are not allowed to leave and re-enter.
