Employees must contact the Visa Office before traveling outside the U.S., regardless of the validity of their visa stamp. Before traveling, be sure your passport and U.S. visa stamp is unexpired, to ensure re-admission to the U.S. The Visa Office can assist in confirming whether an entry visa is required for the destination country. If the travel abroad is for longer than 30 days, certain training is required by the Department of State prior to departure. For more information about travel generally, click here.
