Your visa is the stamp in your passport that was issued to you by a U.S. consulate or embassy abroad. It is considered an entry document, so it only needs to be valid when you travel and plan to re-enter the United States. If it expires while you are studying in the United States, and you have no plans to travel outside the U.S., you will still be in status.
International students usually come to the United States with either a J-1 or F-1 visa.
F-1 Student Visa
The F-1 is the most common visa for undergraduate students at Saint Louis University. After you are admitted to the University, SLU will send you a Form I-20, which you will use to get the F-1 student visa.
J-1 Exchange Visitor Visa
The J-1 exchange visitor visa is for students who will be attending Saint Louis University temporarily (one or two semesters). After you are admitted to the University, SLU will send you a Form DS-2019, which you will use to get the J-1 exchange visitor visa. Some exchange visitors are subject to a two year home residence requirement. Learn more about this requirement.
