Filled in information is incorrect or incomplete
If the ESTA application form is intentionally or unintentionally filled out incorrectly or incompletely, the application may be approved as usual, but it will not be valid. The Immigration Service does not have access to information about every traveler in the world and therefore cannot detect all errors. For example, an incorrectly filled in date of birth will not cause the application to be rejected. The ESTA will be issued, but it will not be valid. There are times when travelers only notice this when checking in at the airport. The airline will indicate that there is no valid ESTA linked to your passport details. The fact that the document was issued based on erroneous information is irrelevant to the airline. This problem can only be solved by submitting a completely new ESTA application.
