How much does it cost

Is she from Ghana by any chance?

The issue is from where, to where.

A passport issued by the country you are a citizen of. A visa comes from the country you wish to visit.

For example, Ghana going to America.
The passport and visa is only about 300 USD.

There is no medical check requirement, there is no BTA (Basic Travel Allowance), no requirement of money in the bank and no police background check

DON'T GET SCAMMED! I know she loves you and looks great but...
