I opened a bank account with Fifth Third in Ohio without a SSN. I showed them my Visa and they were able to process it without the SSN but asked me to provide it when it arrived. I finally got mine the other day so just need to advise the bank. If you log into internet banking you just need to put in your card number rather than your SSN to log in (same goes for making calls to the bank).
As far as taking your money from the UK to the US. I transfered mine to my partners US account. To do this you need to physically go into your bank (you will need the bank you are transferring to account no, IBAN no. etc). Call your bank and ask them exactly what they need to bring in to make the transaction. Fill the form in, pay a fee (mine was about £20 regardless of how much you are moving - receiving fee was about the same my partners end but it varies from bank to bank) and your money can be moved. Think it took a couple of working days certainly no more than five.
I would advise keeping your UK bank account open (even with just a small amount in incase you decide to move back with your partner or if you want to visit the UK you already have an account). Most UK banks will accept an international address so I get info sent to me in the US.
Although HSBC have branches worldwide they are NOT linked in regards to if you have a UK account you still need to apply the same way for a US one.
Hope this helps.

Hey guys,
Ive banked with the HSBC,here in the UK for about seven years now.I asked them if i could close my UK account and reopen one (with the HSBC) in the US for when I move there.They said it takes four weeks and that they could have one set up for me no problem.
My understanding is that you cant open a bank account in the US until you are in posession of a social security number,which takes a while to get.So if thats the case what am I to do with my account?.I dont want to go and leave my UK account open in the UK.What do you do,carry your entire savings over to the US in your pockets?.
Can anyone shed some light on this?.
Thanks
