We are planning to take Bankers Draft cheques made in US dollars from our accounts in the UK.
I am hoping that they can do them here! As we do not have a bank account in the USA so we can't transfer yet!
hope this helps!
You can set up with your UK banks to wire transfer into a new account once its opened - and if unsure about whether the bank you want to open an account with will take the bankers draft (most should do it but I know American banks can be 'difficult') then have your fiance call them and ASK.
To the OP: yes you can keep a UK bank account open (it may depend on your bank however - it is useful to retain a UK address if possible) however you will need to declare it on your US tax return that you have funds in foreign banks. Also make sure you sort out your UK tax situation with the Inland revenue before you leave (if you are liable for UK tax) as there is an agreement between the UK and US about not taxing twice in both places.
The IRS website is quite helpful with info about that.
There is no limit on international wire transfers, as already stated, but amounts over $10k must be declared to customs. Ditto if you are bringing cash, cheques, traveller cheques or bank drafts - ANY form of currency over $10k must be declared or it CAN BE SEIZED, and the bearer subject to prosecution.
