ESTA: New Entry Procedures for VWP Countries
On Jan. 12, the U.S. Department of Homeland Security enacted the
Electronic System for Travel Authorization (ESTA). This new entry program requires nationals from Visa Waiver Program (VWP) countries to register before traveling to the U.S., and will replace the I-94W form previously used by some travelers.
In order to obtain an ESTA, travelers will need to submit information including their name, birth date, passport number, flight number and U.S. destination address. Each ESTA will be valid for up to two years and will allow visitors unlimited travel to the U.S. during that period. Note that ESTAs will
not be issued to any traveler whose passport will expire within six months of the application for an ESTA.
Obtain an ESTA now.
