do you need a visa to travel to the US?

If you are British then you can get a visitor visa at the border for a maximum 90 days under the visa waiver program. The length of time is at the discretion of the border guard but cannot be longer than 90 days. This assumes you do not have a criminal record and that your passport is a biometric passport if issued on or after 26 October 2006 (machine readable if issued before 26 October 2006). If these assumption are incorrect, you need to visit the US embassy to apply for the visa.

YES YOU DO. IT DEPENDS WHAT COUNTRY YOU ARE TRAVELING FROM. MANY U.S. ALLY COUNTRY RESIDENTS NEED VISAS, BUT MANY NON-ALLY COUNTRIES DON'T NEED A VISA. HOW DO YOU EXPLAIN THAT?

It all depends on what country you are flying from, what your duration will be in the United States, and what is your business in the USA.

If you are travelling to the US, from the UK, for a duration of 90 days or less, for holiday purposes, then no, you don't require a visa. This is because of the Visa Waiver Scheme that was introduced in 2000, where countries who have signed up to this scheme, enables for members of other countries to fly to other countries without a need for a visa, as long as they have a machine readable passport.

There are over 30 countries that have joined this scheme, and only require for you to a member of a state that is part of the Visa Waiver scheme, that your duration in the desired country is not longer for 90 days and that you are going to the country for pleasure (rather than business- meaning where you are looking to earn money)

Not if your staying for less than 3 months.

not if you'e from the uk and as long as you're not staying more than 90 days

No, Singaporeans do not need visas for the US.
You have to however check with the US Embassy in your country.

yes. due to all the fear of terrorism, everyone needs a visa to visit these days. easy to get though, call the embassy or consolate near you.

we do ! i'm from Romania

yep. if ur from another country. cause my uncle wants to come to U.S.A (which is where iam right now) to visit me and my parents and my sister and he has to get a visa to come here.

I think it depends on where you are from and how long you plan to stay.

Where are you coming from?

It depends on which country you're from. For example:
From European Union = No.
From China = Yes.

unless youve got a criminal record you can just fill out the visa waiver forms at teh airport make sure you've got at least 6 months left on your passport when u return
