Does the expiration date on a student visa determine how long the student can remain in the U.S.?
Although many people believe that the visa expiration date determines when they must depart the U.S., this is NOT true. The visa is used as an entry document to the U.S., accompanying your I-20 and passport. The expiration date on your visa determines the LAST DATE YOU MAY ENTER THE U.S. on that visa, along with other required documents. If your visa expires while you are still in the U.S. and studying full-time, maintaining your F-1 status, you are not in violation of status. However, if you leave the U.S. after that visa expires, you will be required to obtain a new visa before being allowed to re-enter the U.S.
