Visa
All visitors to the United States, including international students, must enter with a visa (unless their county is part of the visa waiver program). All students must enter with a valid I-20. Once students are admitted to the United States, status is maintained by the I-94 and the I-20 forms. Students who wish to leave the county may use the same visa to re-enter as long as it has not expired. Students who leave the country and their visa has expired, must apply for a new visa in their home country.
