The Student and Exchange Visitor Information System (SEVIS) is a database that tracks the academic status of F, M, and J nonimmigrant students. The authority for SEVIS is set forth in 8 U.S.C. § 1372. The legislation for SEVIS was enacted in response to the 1993 World Trade Center bombing in which an out-of-status foreign student was a key conspirator in the attack. Further enhancements were added to SEVIS by the US PATRIOT Act of 2001, and the Enhanced Border Security and Visa Entry Reform Act of 2002. The Homeland Security Act requires that ICE use SEVIS information for enforcement purposes. These congressional acts were passed in response to the 9/11 terrorist attacks, and strengthened and required the full implementation of SEVIS. The information contained in SEVIS is input by various academic institutions and exchange visitor programs. These schools are certified by ICE to use SEVIS and are also authorized to petition for foreign students and exchange visitors to enter the United States as nonimmigrant students. The information in SEVIS is used by ICE to carry out administrative enforcement of individual status violators, conduct criminal investigations of smuggling and fraud related to SEVIS, and for national security operations. Other stakeholders that use SEVIS include U.S. Citizenship and Immigration Services (CIS), U.S. Customs and Border Protection (CBP), and the Department of State Embassy and Consular offices. SEVIS is an integral component of the DHS national security strategy.
