CBP has announced that the Electronic System for Travel Authorization (ESTA) web application has been modified to provide for multiple applications to be submitted and paid for in one transaction. As of August 15th, applicants should be able to create a Group ID that would allow a group of travelers (e.g., a family or a tour group) to enter up to 50 ESTA applications and pay via same credit card entered just one time. ESTA provides an electronic travel authorization to nationals of Visa Waiver program participating countries, and ESTA online applications must be completed no later than 72 hours in advance of travel to the U.S. ESTA clearance is usually valid for multiple trips to the U.S. over a 2 year period.
