Automatic Visa Revalidation permits F-1, F-2, J-1 and J-2 students/dependents (unless you are from Iraq, Iran, Syria, Libya, Sudan, North Korea, or Cuba) to return to the U.S. following brief trips of 30 days or less to Canada, Mexico, or adjacent island (except Cuba) when the F or J visa has expired or after an approved change of status. Please note that automatic revalidation will not be available for anyone who applies for a visa while outside the U.S. If this situation applies to you, contact O.C.
