To make your visit to the United States, you must either travel under the country's Visa Waiver programme (with an ‘ESTA'), or have a US visa (or be a US citizen, of course).
All travellers wishing to enter the US under the Visa Waiver Programme now need to hold a passport with an integrated chip (an ePassport).
An ESTA allows you to stay in the US under the Visa Waiver programme for up to 90 days and allows travel to Mexico, Canada and the Caribbean.
An ESTA is valid for two years, (or less if your passport expires in that time).
To obtain your ESTA:
You must apply at least 72 hours before you travel.
You must hold an individual machine-readable passport (if you don't, you'll need to get a visa instead).
Provide accurate information on your ESTA application.
Usually you will receive a response in seconds, but for very few passengers it could take up to 72 hours.
If your ESTA is denied, you will need to get a visa.
If you already have a visa for the US, you will not need an ESTA.
You must apply online for your ESTA.
