You would need to fill out and submit a new ESTA application in 24 hours, and you will need
to pay the fee for the new application. Once the new application is submitted, the previous
one will be automatically rendered void. You will also not be able to change the answers
to your yes or no eligibility questions, so ensure these are answered correctly
before you submit payment.
Other mistakes, such as destinations, city of embarkation, email address, phone number,
flight details, the address where you will be staying in the United States, etc., which
in themselves have no effect on the decision for your registration, can be updated without
the submission of a new application. This information can be edited at any time by clicking
on the “Update or Check Status button” on your ESTA form. You will be reminded to check the
details provided a number of times before you
submit the form
and it is advised that you ensure that all information is correct before submitting your application
so that everything can proceed smoothly.
