Ohh, okay. If I don't get my own British account, I guess the other option would be transferring it into my boyfriend's account.
You might find when you get here that it will be easier for you to have a UK bank account in order to pay for a lot of things - usually UK universities will have special arrangements with certain banks so that international students can easily open bank accounts.
Having said that though, I lived in the US on a student visa for a year back in 2003/04 and I didn't open a US bank account - I just used my UK Mastercard and cash/traveller's cheques that I'd taken with me to pay for things.
The Visa card is great for ATMs and online payments. Though since it's not chip and pin, if I'm paying for something in person then I usually just use cash.
Just a tip: even if UK stores say they only take chip and pin cards, they should still be able to process swipe cards, because many foreign visitors and tourists may not have chip and pin.
The cash registers should still have the facilities to process swipe cards, it's just that the employees will have been told they can only take chip and pin cards... so if you want to pay by card, it's worth checking with a member of staff or a manager to see if they will process it for you (I used to work in retail and we were still able to process swipe cards even after chip and pin came in).
