questa è la risposta che abbiamo ricevuto, dite che possiamo stare tranquilli? Response Via Email (ESTA CBP Officer) 06/10/2015 08:55 AM Once you answer yes/no to the in transit question you will not have an option to change your answer. Even though you chose or failed to choose "in transit" the ESTA application will remain valid for travel. All you need to do is have a physical address written down and available in case an officer requests it from you. You DO NOT need to take any other action. It is no longer mandatory to update the flight information on the ESTA application. We receive flight details from the airline prior to your arrival to the United States. Respectfully, ESTA Team
