As a US citizen, can I fly to UK, open a bank account there with my US passport and get a debit card like you to use at pokerrooms/casinos/sportsbooks or do you need to be a UK resident? Do I need a "PO Box" or physical address in UK? Can I do the same for Bahamas? Caymans?
[/ QUOTE ]I guess if they let you open an account you will receive a debit card with the account. You want what is called a current account. You will receive a check book and debit card if they let you open the account. A guy from the USA said on this site that he just walked in to a UK bank and used his US passport as I.D. and they let him have an account. It's just a long way to come though if there's any chance they won't let you have one.
Here is a list of some of the UK banks I guess you could contact some of them and ask if it's possible for them to open you a current account without having to visit the UK.

I also found this
http://www.offshore.hsbc.com/1/2/int...e-bank-account It's an offshore account with HSBC who are a reputable bank. Their current account comes with a debit card and you can have an account in Pound's, dollar's or Euro's. The only snag is you need to maintain a balance of at least £5000 or $10,000. As I say the account is offshore on the Island of Jersey, which is UK owned. From looking at their website you can fill in your application form online then print it, sign it and send it off, all look pretty simple. This could be a good possibility, hope this helps.
