3/9/2010 - The Department of Homeland Security announced today that Greece will become the latest country included in the Visa Waiver Program.  The Visa Waiver program allows citizens of the participating country to visit the U.S. as a visitor, for up to 90 days, without first obtaining a visitor's visa from a U.S. Consulate abroad.   Citizens of visa waiver countries must go online and register their travels with ESTA before traveling to the U.S.   Thirty-five other countries currently participate in the Visa Waiver Program.
