Can I find out the reason my application was denied?

DHS has carefully designed the ESTA program to ensure that travel authorization is denied only to those individuals who are ineligible for entry into the United States under the Visa Waiver Program or those whose travel would pose a threat to law enforcement or security. Although the ESTA website has a link to the DHS Travel Redress Inquiry Program (TRIP) website, there is no guarantee that a request for redress through DHS TRIP will resolve the ineligibility under the Visa Waiver Program that caused the applicant to be denied the ESTA application.

Please note that embassies and consulates cannot provide detailed information about ESTA denials or resolve the problem that caused the ESTA denial. Embassies and consulates will be able to process a nonimmigrant visa application, which, if approved, will be the only way to allow a traveler whose ESTA application was denied to enter the United States.
