Those planning their first trip into the United States with the chance they will like to make a repeat visit at some time in the near future, would be well advised to consider applying for ESTA authorization.
Before any application work is commenced, it is important to understand the regulations that apply to durations of stay and the total term of the ESTA authorization, which can be used for multiple entries.
The two important questions to ask are: How long is ESTA Valid for a single stay and how long is ESTA valid in total.
WHAT IS THE PERMITTED DURATION OF STAY WITH AN ESTA FOR A SINGLE VISIT?
The ESTA (Electronic System for Travel Authorization) program was implemented back in 2009, this was done to provide citizens from countries with program membership to obtain their VISA with greater simplicity.
It is important to understand that this new system does operate with some very specific restrictions. The most important being, if you are planning a trip to the US under ESTA authorization, you will only be permitted to stay in the country for less than three months. Longer stays will require a different VISE method.
It is also important to understand that the duration of your stay is limited to 90 days or three months, regardless of the purpose of your stay. You will only have this time period while using the ESTA Pass, no longer stays are permitted for vacations or business.
WHAT IS THE TOTAL PERIOD AN ESTA AUTHORIZATION WILL BE VALID?
Although the period of the visit into the US can only be for a maximum of 90 days, once ESTA authorization has been granted, it can be used on many separate occasions; in other words for various trips into the US.
The ESTA authorization is granted for terms of two years from the date the authorization is granted, not from the date of your first trip into the US.
If a person has already obtained their ESTA authorization for trips into the United States less than two years ago and they wish to make another trip into the US, there will be no need to recommence the ESTA application process.
Nevertheless, it would be a good idea to run a check over all the details to make sure that none of your personal information has changed in this time. For example, if you have renewed any important travel documents such as your passport, it will be important that all data that has changed be updated into your ESTA authorization before you hope to use it again.
Once the authorization period has ended, there will be no records of any of this or any previous travel documents kept in the records of the US government. This means that if you are planning another trip into the US, you will need to reassume the application process. Of course, all fees related to processing your application will need to be paid again.
In Summary — It is important that appropriate preparations are completed before you plan to visit the United States, even for those with the highly convenient ESTA authorization.
