Assuming you are talking about deposit accounts, at least put some logic and predictability behind your decisions. Saying that you don't open accounts for Hungarians simply makes no sense.
Saying that you only open accounts for non U.S. persons who have a U.S. TIN gives your employees an objective standard and does not discriminate based on national origin; i.e. if she's got a TIN you don't care what country she's from.
