This service is a federal web-based system for maintaining information on international nonimmigrant students and exchange visitors in the United States. It is the core technology for the Department of Homeland Security (DHS) in this critical mission. Student data is exchanged with SEVIS via Terra Dotta ISSS that is run by the Student Life division. ITS maintains an integration between ISSS and the Student Administration System for student data, which is needed for ISSS to operate and integrate with DHS.
