ESTA denied status may occur when the traveler does not meet the Visa Waiver Program requirements or is not eligible to travel under ESTA.
Common examples include certain travel history or nationality restrictions that make the traveler ineligible for the Visa Waiver Program.
If your application is rejected, it does not necessarily mean that travel to the United States is permanently impossible. However, if you still wish to continue with the trip, you will need to apply for a U.S. visa separately.
Before traveling, please review your passport details, nationality, and travel history, and apply for ESTA before departure.
