In the United States, the F visas are a type of non-immigrant student visa that allows foreigners to pursue education (academic studies and/or language training programs) in the United States. F-1 students must maintain a full course of study. F-1 visas are only issued in U.S. embassies and consulates outside the United States, although extensions of stay and changes of status may be possible within the United States. Prospective F-1 students must apply at the schools and receive a form I-20 in order to apply for an F-1 visa. F-1 students must show that they are able to support themselves during their stay in the U.S., as their opportunities for legal employment are quite limited. F-2 visas are given to dependents of an F-1 student. F-2 visa-holders are prohibited from any form of compensated employment. However, minor children may attend public schools. Finally, the F-3 visa is issued to Canadians and Mexicans who commute across the border to attend American schools.
To pursue studies in F status at a college, university, or vocational school, it is necessary that the institution be a participant in the Student and Exchange Visitor Program (SEVP). An institution can acquire SEVP certification by filing Form I-17 with U.S. Immigration and Customs Enforcement (this is a one-time process). Note that an institution can be SEVP-certified despite not holding national or regional accreditation. Conversely, an institution may hold national or regional accreditation but may have chosen not to obtain SEVP certification if it does not intend to admit international students in the F, J, or M status.
A large university typically has an international office that manages its participation in the SEVP, and all the DSOs work for this office. The international office manages updates to the Student and Exchange Visitor Information System (SEVIS) record for students and issuing of new Form I-20s. Students who have any change to their plans (such as program end date, course load, leave of absence, return from leave of absence) must communicate these changes with their international office.
It is possible to obtain a F-1 visa to pursue studies at a secondary school (grades 9-12). As is the case with other institutions, the secondary school must be SEVP-certified. The school may be a public (government-funded) school or a private school. In the case of a public school, the student may attend for a maximum period of 12 months and must reimburse the school for the full per-capita cost of attendance. Neither of these requirements apply for students attending private schools.
