If your ESTA has expired or you have a new passport and require a new ESTA, you must submit a new application.
You will also need to reapply for an ESTA if your gender, citizenship, or name changes (marriage, adoption, or divorce) have occurred, or if your responses to security questions have changed.
You will then have to wait for a fresh ESTA approval. And, as you know, it normally takes no more than 72 hours if the application and background checks go smoothly. The reapplication procedure is the same as the initial application procedure. Your former ESTA will be invalidated and replaced with a new reference number and expiry date.
When you receive a fresh ESTA, the most important thing to remember is the ESTA expiration date.
After your ESTA is renewed, you will be permitted to go to the United States for business, travel, or transit if your visit does not exceed 90 days and all other aspects of your trip meet the conditions for Visa-free travel to the United States.
If you need to reapply for an ESTA before travelling to the United States, you must use the original ESTA application form.
You can reapply for an ESTA when your current ESTA is valid. This is specific to when the validity of your present ESTA looks to be insufficient to support your stay in the US throughout the period of your travel.
