How do they even get visas to come here
they come here on tourist visas, then get forced to overstay
girl found recently is typical:
arrives at Heathrow to visit a friend
"Friend" doesn't appear, instead a Chinese guy says "hello", and offers to look after her
Chinese guy shows her around London for a few days, one night they end up in a chinese run gambling den.
She's helped to run up a debt of $8000 - she didn't know it was for real, had no idea of exchange rates.
She's told she can wipe the debt out by whoring. They take her passport, send her north with Chinese guy as pimp.
She works out of a top-floor flat (harder to escape), all her clothes are taken off her, is fed nothing, regularly beaten, and is trained to be "enthusiastic" to arriving customers - so much so that her pathetic kisses and greetings are like a little puppy dog.
For her safety I'm not going to say which girl, or where, but the truth is this is proving to be a common route for Chinese girls
