How does ESTA work?
ESTA has been introduced by The United States Department of Homeland Security. Under ESTA, an individual traveling to the USA on the VWP or Visa Waiver Program gets electronic travel authorization before boarding a carrier for traveling by sea or by air to the USA.
This new system of travel authorization does not come with the guarantee of admissibility to USA at the US port of entry. However, it authorizes travelers to board carriers destined for the USA. ESTA came into being on 1st August 2007, and it has been effective since 12th January 2009. It is important to note that people possessing a valid visa for the United States do not need to get any travel authorization under ESTA.
