and she lives in Portugal a country that does not allow you to change your name to anything that is not portuguese , The laws of UK Australia Canada and the USA of course allow you to call yourself anything you want provided there is no intent to do something illegal. i cant see that getting a credit card in that name would be so difficult.

I remember when I was started working where I am now we had to give our names for government clearance and one of the other applicants was asked a week later to fill in a form saying that he wanted his pay to go to to himself because government records showed he a man in his fifties looked blank he had no idea that he had a different name on his birth certificate. And signed his usual name on the form saying he wanted the money paid to his usual name.
