I don't care to live in the USA, but I would say that my US citizenship is my most valuable resource. (If that's the right way of saying it.)
Anywhere in the world, if a smoking hot, rich, brilliant, funny, creative, intellectually curious, athletic, caring, considerate woman is willing to put up with a guy like me so that she can have permanent legal access to the USA, I'm totally game. Why would someone take such a valuable commodity and flush it down the toilet?
Incontheivable!!
