What is the US ESTA?
A simple explanation of the Electronic System for Travel Authorization.
The US ESTA, short for Electronic System for Travel Authorization, is an online travel permission that allows eligible travellers to visit the United States for tourism, business meetings, or short visits without applying for a traditional US visa. It was introduced by the United States government to make travel easier for people coming from countries that take part in the Visa Waiver Program. Instead of going to an embassy in person, you simply complete an ESTA application online before your trip, and the result is sent to you by email.
An approved ESTA USA authorisation is valid for two years from the date it is issued, or until your passport expires, whichever comes first. During those two years you can travel to the United States as many times as you like, with each visit lasting up to ninety days. This makes it a flexible and convenient option for holidaymakers, business travellers, and people visiting friends and family in America.
It is important to remember that the ESTA is not a US visa. It is a separate kind of travel permission designed only for short stays under the Visa Waiver Program. If you plan to study, work, or live in the United States, you will need to apply for the appropriate US visa instead. For most short trips, however, the ESTA is the simplest and quickest way to receive permission to board your flight.
