The ladies here may be from across the way, but I agree 100%... Im in the US as well, and I am a black provider too, and I can tell you...if they are the ones telling you it will be hard to get work as a black provider, then they are putting craziness in your head.
This is 100% trafficking and a scam. I really suggest that you block and forget the lawyer, this other so called escort, all of it. If you want to go to Seattle and work, then yes, book your own ticket, get your own hotel, and go on out there. I work in FL, and its pretty slow here, so I tour on my own. It can be done...I started touring about 4 months after I started escorting. Booked myself a roundtrip ticket, got a hotel, advertised myself in the city I wanted to go to, got a few prebooks and I was off.
There have been stories of a guy here in FL who would fly girls here promising them the same things this guy is offering you...and he had a female accomplice who was actually his wife or gf, I forget which, who would say she was an escort he had helped out, which was not true..she was jsut part of the scam. They would end up trapping the girl in his house, have her work while taking the money she made, leaving her with no money to get back home and no way to leave. It was all mental...he had them convinced that after a certain timeframe, that he would give them all their earnings at once...never happened.
Please take heed and dont say anything else to these people.
