You cant open a bank account for another country in a different country.
I assumed when I moved to the UK I could walk into an AIB and open on as I was Irish, not the case.
You will need to get a NI number to work over, similar to PPS so do that asap, will have your address on it. Also if ur sharing a flat/ house ask them to put your name on the council tax bill or a utility bill if you can prior to moving over so you will have something with an address on.
You will more than likely be issued with a electron card to start with as you wont have any credit history there,this only works by using an atm, not a lazer/debit card! (pain in the ass)
