My girl in accra, ghana lives there and she wants to come to the u.s. and she said that she went to her embassy there and they told her it would cost her 750.00$ is that true.

No. Scam alert! More of our members will give you additional information, or read other threads on this site about Ghana romance scams.

Nope, It would cost less than 100 USD. First they do not use USK, they use their own money.

The passport from Ghana, and the US visa both cost less than 300 USK.

This is the first sign of a common scam where they over price everything.

Also. she does not go to "HER" embassy to get a passport, she just goes to her Immigration office. There are no Ghana embassy in Ghana. An embassy is a office located outside their country.
