Most commonly, you will receive an almost immediate response to your ESTA application, based on your eligibility under the Visa Waiver Program. There are 3 types of possible responses: Authorization Approved, Authorization Pending, and Travel not Authorized. Those who have received an approval are authorised to travel to the United States under the Visa Waiver Program.
ESTA Authorization Pending status usually does not last over 72 hours. However, there are single cases, which might cause the Government of the United States to review your application longer. ESTA pending status refers to the undergoing review of your overall application as well as all the details provided in it.
If your current status is “Authorization Pending“, after completing the online ESTA form, please wait a couple of hours, refresh the page and check your status again.
In rare cases, the status “No application found” may appear after an ESTA pending status. If this is the case, your application has not been made successfully. “Travel not Authorized” is another possible response for unsuccessful applications.
In the occasions when an applicant has received an ESTA application rejection, he/she still has the option of entering the United States. They will not be able to do so under the Visa Waiver Program, however, all unsuccessful ESTA applications may apply for a B1 Work Visa or a B2 Tourist Visa.
