With the holidays rapidly approaching, international travelers using the Electronic System for Travel Authorization (ESTA) for travel to the United States are reminded to apply as soon as possible but not less than 72 hours before their international flight is scheduled to depart. Due to changes in the ESTA application processing, real-time approvals will no longer be available. Travelers who participate in the Visa Waiver Program (VWP) traveling to the U.S. are strongly encouraged to apply for ESTA authorization at the time of booking their trip and no later than 72 hours prior to departure. Applicants who apply on the same day of their flight’s departure risk not having an approved ESTA prior to their scheduled departure and being denied boarding their flight. ESTA authorization, which is available online, is valid for two years and costs $14 to apply.
