Yes. A family member, guardian, friend, or travel agency may apply for ESTA on behalf of someone else.
However, the passport details and personal information must be entered accurately for the actual traveler.
The review is based on the traveler’s information, not the person helping with the application.
So, applying on behalf of someone else is allowed, but incorrect information may affect approval or later travel procedures.
Before submitting the application, it is best to review all details carefully and apply for ESTA with caution.
