You should ensure that you have sufficient funds at your disposal when you arrive in the UK. Opening a bank account in the UK is not straightforward if you move from overseas and it may take a couple of weeks before you are able to access this. In addition, you may need to pay a deposit and/or rent in advance of moving into rented accommodation, and cover any relocation expenses you are entitled to claim before these can be refunded.
Most shops in the UK accept debit/credit cards from other countries. You should check the terms and conditions outlined in your credit card agreement, as you may incur fees for using your card abroad.
Staff moving to work at Queen’s may wish to check with their existing bank to see if they have a presence in Northern Ireland and whether they can help you with setting up an account. Your bank in your home country may also be able to advise you on how to transfer funds to the UK if you have not yet opened a UK bank account.
