No. ESTA cannot normally be canceled freely by the applicant after submission, and a refund is not automatically available.
Once the application has been submitted, cancellation is generally not possible, and the fee is not refunded simply because the traveler changes plans.
A canceled trip or a schedule change does not automatically make an ESTA refund possible.
In addition, if incorrect information was entered after submission, the issue may not be resolved through cancellation alone, and a new application may be required.
For that reason, passport details and travel information should be checked carefully before submitting the ESTA application.
If the application has already been submitted, the correct step is to check the current status first and then determine whether a new application is needed.
