Can anyone show me a picture of one because the one that the girl sent me is just a simple test for something else not hiv??

First please don't tell us, that there is this girl, and she is just totally in love with you.

And you had to send her money for a medicial exam, for passport and visa?

First of course all of this only costs a couple hundred US dollars.

Check out the US embassy website for Ghana, that nation is the number one nation for dating fraud. They have rooms full of people who use computer and phone and often use the same passport info for various dating people.

Sounds like scam... be careful. The best thing to do is tell "her" that you are visiting "her" in person. She will disappear immediately.
