As part of the U.S. Department of Homeland Security, the Student Exchange and Visitor Program (SEVP) provides approval and oversight to schools that enroll F nonimmigrant students and gives guidance to both schools and students about the requirements for maintaining their status. SEVP uses the Student and Exchange Visitor Information System (SEVIS) to track and monitor schools, exchange visitor programs, and F and J non-immigrants while they participate in the U.S. education system. The vast majority of international students at Castleton have an F1 non-immigrant visa, which means they are in the United States to pursue a full course of academic study. The rules regulating F1 students are taken seriously by SEVP and it is the student’s responsibility to understand and comply with these regulations. The goal of every international student should be to stay "in-status", meaning they are following the rules. By not respecting the rules, a student is considered "out of status", which results in penalties including the possible termination of his/her F status. The International Student Office (ISO) sponsors a non-immigration workshop at the start of each semester for new international students to help them understand the regulations. Throughout the academic year, the ISO provides information and advises students on non-immigration issues to help them stay in-status while taking advantage of the benefits afforded to them as an F1 student.
