Maybe you have already acquired ESTA authorisation in the past, or schedule many trips to the United States in the coming months, and you want to be aware if you can make numerous trips with the same ESTA authorisation. To gain an understanding of the answers here we have prepared some clarifications and details on the validity period of your authorisation and the conditions to carry out to talk over again this authorisation for various visits.
In general an ESTA authorisation, once acquired, is valid for a period of two years. This genuineness period starts when you receive your travel authorisation from the American authorities, not from when you submit your application. Probably, you can therefore reuse this authorisation during the whole of its two year period of validity to make many trips to the USA. However, you will require meeting specific conditions that we will cover here as a whole. To use your ESTA authorisation many times during its validity period you should meet the following requirements.
Firstly, your biometric or electronic passport number should be as similar as that used during your first trip. It is basically the passport number that your ESTA authorisation is linked with electronically. Of course, the validity period of this passport should include the grand total of your stay in the United States. Also, this ESTA authorisation is only valid for stays of less than 90 days. You cannot use it for longer stays or to extend the duration of your stay in the USA. In the latter condition you will have to exit American territory and sow the seeds of a new ESTA application. Your private situation must not have modified. If you have got married, divorced or changed your civil status then you can no longer use your ESTA authorisation for another trip. Ultimately, you should show to be true that your early responses to all questions asked remain correct. This specifically covers the questions in the last part of the form.
To reuse your ESTA authorisation for further visits after your accepted trip, you should bring up-to-date your online application form. To do this you should return to the website where you give in your initial application, or the official ESTA website as applicable. Make sure that you have your genuine reference number at hand. This number was given to you during the submission of your first ESTA application. You should then give an assurance the about the exactness of all detail entered with your present situation, or change it as compulsory if changes have occurred. Please keep in mind, in the latter case, it may be feasible that the American authorities refuse to accept you authorisation, even if you were initially granted it with your initial application.
