For a woman to come here on tourist visa how much she need to show immigration?

Oh dear.
Smells like a scam to me.
Let me guess she claims it's several thousand dollars!

If she is coming to the US there is no "money needed to show anyone" and the visa and passport only costs about 300 dollars.

Asking for this money is a common scam.

In most cases it is not even women or if it is, it is room full of people who do this for a job.
