The USA ESTA is an entry requirement for visa-exempt visitors. Travelers of certain nationalities need to register online to have their trip to the United States authorized.
ESTA stands for Electronic System for Travel Authorization. It was introduced in 2009 by the Visa Waiver Program (VWP).
The ESTA application form is available for citizens of eligible countries traveling to the United States for tourism, transit, and business purposes.
The ESTA USA is valid for a total of 2 years from the date of issue, and allows multiple entries for a maximum stay of 90 days each time.
Eligible travelers are required to complete the simple ESTA application form online, which only takes a few minutes to complete with personal and passport information.
It is also necessary for applicants to answer a few simple questions related to security and health matters. The ESTA allows the Department of Homeland Security of the United States to pre-screen passengers before traveling to the United States for safety.
Those eligible to apply for the ESTA Travel Authorization for the United States are able to travel to the United States on short notice. This avoids having to go through the trouble of applying for a traditional visa at an embassy or consulate.
Foreign nationals traveling to the USA for other purposes such as to work or study are required to contact a United States Embassy or Consulate in their country of residence.
