If you do a search you'll see that many of us did this. I opened up a current account (checking) with Citibank. I needed a reference letter from my US bank, a reference letter from my employer, and passport. It took a while but they did open one up. I do not have a US dollar account but you can open one up...you have to have a certain amount being paid into your accounts per month (may be about £2000) to do it (or at least to have no fees).
