ESTA is an automated system that determines the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP). Authorization via ESTA does not determine whether a traveler is admissible to the United States. U.S. Customs and Border Protection officers determine admissibility upon travelers’ arrival. The ESTA application collects biographic information and answers to VWP eligibility questions. ESTA applications may be submitted at any time prior to travel, though it is recommended that travelers apply as soon as they begin preparing travel plans or prior to purchasing airline tickets.

Please note that as of January 2016, the Visa Waiver Program has changed. Under the new changes, the following categories of travelers are no longer eligible to travel or be admitted to the United States under the Visa Waiver Program, and will need to apply for, and go through the standard Visa application process:
  • Nationals of VWP countries who have traveled or been present in Iran, Iraq, Sudan, or Syria on or after March 1, 2011 (with limited exceptions)
  • Nationals of VWP countries who are also nationals of Iran, Iraq, Sudan, or Syria. (Travelers who are known to fall into the dual national category noted above should have received notice via email on or about January 21, 2016 that their current ESTA is no longer valid).
These restrictions do not apply to VWP travelers whose presence in Iraq, Syria, Iran, or Sudan was to perform military service in the armed forces of a program country, or in order to carry out official duties as a full-time employee of the government of a program country. These military and official government services exceptions, however, do not apply to the dual national restriction.

The Act includes other changes to the VWP to promote enhanced information sharing of terrorism and criminal data, and use of INTERPOL databases and notices for border screening purpose. The vast majority of VWP eligible travelers will not be affected by the legislation.
