Employees and visitors holding U.S. visas should contact the Visa Office prior to any travel abroad, even if such travel was previously discussed.
The current situation with re-entering the U.S. is precarious, as stricter grounds for National Interest Waiver exemptions have been instituted by the U.S. Department of State.
Regardless of the visa status, re-entry to the U.S. is not guaranteed.
Contact the Visa Office prior to any travel abroad.
