I would like to know how much a visa,passport costs from Ghana to the United states.I have met a girl in Ghana is there anyway to find out if she is real and that the picture I have of her is the real thing.Would it be dangerous for me to go to Ghana.This woman has called me on the phone several times.

How should I handle a possible relationship with a woman from Ghana

Um, I don't think this is the right place to ask this..

Google her name-there are various scams out there.

If I were you, I will go to see her... instead of trying to get her here.
