I think you only need a visa if you have a criminal record?
As pointed out, you are allowed to go for 90-days at a time. What is the period you then need to return for the UK for before going back (and how long are you then allowed?)
I'm being lazy, short of it is, never been to 'Merica.
I'm in New York in 5 weeks time. Do I need a visa? What do I need to do?
Also, I have a new spangly machine readable passport, does that help in anyway?
Thanks
Are you eligible for the visa waiver program? Most people are, but those with convictions may need to get a B1 or B2 visa from the London embassy. I have one due to some daft ladies at the US marriage office refusing a marriage license without one for example. (advantages of having a visa are better legal status and 6 month visit period btw).
So, assuming you don't need one, just sign up for ESTA as everyone above has advised and roll with the VWP.
Have a great time!
P. S. Get that ESTA done ASAP... Like tonight.
you will need to do the API with the airline in advance too
re criminal record that is not entirely correct, there are times you can have been arrested but not even charged with anything but still need to get a visa
Why the urgency if it doesn't need to be done until a few days before hand?
API with the airline?
You should also note that you can't do anything on the tourist waiver, no part time work or anything. If you are found in breach or over stay you will never be allowed back in.
