"ENTRY REQUIREMENTS
Most British Citizen passport holders do not need a visa to visit the US on business, pleasure or in transit if they intend to stay in the US for less than 90 days and as long as they have a Machine Readable Passport. This is called the Visa Waiver Programme, and more information on this is available on the US Embassy website (details at the end of this section). If you are unsure whether you are eligible to travel to the USA without a visa, the following Questions and Answers may be helpful.
Is my passport machine readable?
If your passport is machine-readable it will have at the foot of the personal information page (at the back of the passport) 2 lines of text as letters, numbers and chevrons (>>>).If there are no lines of text, then the passport is not machine-readable and you need a visa. The personal information page should also describe your nationality status as, "British Citizen".
Why might I need a visa?
There are reasons why a British traveller will need a visa. These include one or more of the following: (If you think that your situation falls into any of the following categories, you should consult the US Embassy about whether you need to apply for a visa you must do this well in advance of any plans to travel to the US.)

The US Government has legislated that anyone travelling to the US under the Visa Waiver Programme with a passport issued on or after 26 October 2005, will have to have a biometric passport in order to travel visa free. Biometric passports will contain data about the holders face, and may also contain other unique personal information such as fingerprints and iris details. The UK is working on its programme to introduce biometric passports,
but it will not be fully ready in time for the 26 October 2005 deadline. British Citizens who would normally travel under the VWP may therefore require a visa, which will include biometric data, to enter the US on or after 26 October 2005, if their passport is issued after that date and is not biometric."
