This lady has sent me a copy of her visa and passport and wants me to pay for her ticket. Please email me at >removed per site rules< if you can help me thanks

This sounds like a scam.

Very common scam.

Don't send her any money... this is a very popular scam and you are going to fall for it.

If you wish to be foolish enough, ( since this is a scam) you pay for a prepaid ticket with the airline, that can not be cashed in, and if not used, is refunded to you.
It costs more, but can be done.

Once you tell her this, I bet she will tell you reasons you can't, since she wants the money
