FOR BELGIAN TRAVELERS
The Department of Homeland Security (DHS) has announced plans for
the Electronic System for Travel Authorization (ESTA), effective
January 12, 2009. ESTA is an automated system used to
determine the eligibility of visitors to travel to the United
States under the Visa Waiver Program (VWP) and whether such
travel poses any law enforcement or security risk.
