I have been in contact with a woman in Ghana. She has asked me for assistance in helping her to obtain her passport so she can visit me in the US. Can I do this here in the US? If so, can you tell me how much it should cosst, and how to go about doing it?
Thank you.

The normal possport there costs less than 30 dollars, they have a rush one that can be received in about 2 days for 120 dollars.

Now you do know that 99.99 percent of all of their "women" who fall in love with men here are are fraud, some are not even women, others 60 year old women using their granddaughters photos. Or merely women hired to write to 100s' of men just to get money.

After they get the passport money ( normally ask for 100's for this) then they have to bribe someone, then they will need a certain amount o mony in the bank, then it all gets stolen.

Go the US embassy web site for Ghana, you will see most of their site is nothing but warnings about this scam, the biggest scam on the internet right now.
