The holiday season is a popular time for travel and celebration.  Both activities relate to a US Department of State (DOS) policy that can interfere with foreign nationals’ international travel.  Foreign nationals who have been charged with Driving While Intoxicated (DUI) or related charges may have their visa stamps revoked under DOS authority.  This policy, known as “prudential revocation,” can occur without the knowledge of the affected traveler.  For more information, please see our advisory.
