Who can apply for the ESTA to enter the United States
Traveling to the United States is not so complex for everyone. While a document is required to allow non-citizens to enter the territory, it is not mandatory for everyone to apply for a visa. There is a program that exempts a certain group of people from carrying out this procedure, called Visa Waiver Program, which consists of an authorization. This procedure is popularly known as ESTA, in reference to the means by which it is carried out (Electronic System for Travel Authorization).
Under this rule, citizens of 40 nations can apply to enter through this system, which is also called the Visa Waiver Program. For example, countries that are part of the European Union can manage their entry through this modality.
The authorization has a duration of two years, period during which travelers will be able to enter for up to 90 continuous days with no limit on the amount of income. It is important to note that once this period has elapsed, it is not necessary for the person to return to their country of origin to re-enter; he will be able to leave American soil and move to another nation, if she wishes.
