She's has been longing to visit America, she has never traveled out of the country, most times she tried, she end up falling into scam or novice processing the document.
Her long time brother has now contacted her that he will send her an invitation letter, now what happen here is that we wish to do the processing ourselves, she has obtained her passport.

What are the necessary steps after the arrival of the invitation letter?
Like how much could she be expecting to spend on the visa processing?
Mind you she's going for visiting at first with the intention of doing some casual work if available.


Pls I need help on how to go about it.

Goodluck.

The Passport is a good first step. She has to go ahead and pay for her visa fee with the help of the Passport which is 57600 then she will need to get her documents processed
