hi james
i have a lot of polish staff working in the store i work and they are always asking for letters to give to the bank to get a bank account (always lloyds tsb, the polish seem to like that bank). all the bank is after is thier name, address, when started work and that they have a contract with us. i have only been called by the bank once inregard to the letter and that was just to comfirm what was in the letter. so i know that they would accept a letter from a company as proof, not sure about if any governement department or doctor would. as i have only been asked to write ones to give to the bank.
