Currently there are 30 foreign teachers from several different countries whos passports are being held against the teachers will. they are not being returned. Currently the school is moving the teachers from apartment to apartment over the last 3 weeks to avoid the police who are investigating the passport issue. The school does not have a ligitimate locense to hire foreign teachers and if you ever examine the stamp they use on the documents the name of the company stamping the signature and the name of the company you have a contract with are not the same. Also if you look at several different contracts the stamps they use are all different companies. Each payday you have to fight to get the correct amount of money. they have bribed [ ] the jilin education department to look the other way to the tune of 500,000 RMB each year.

Why did the teachers surrender their passports?
Did they get receipts for them?
Have they asked and been told why their passports haven't been returned yet?
How do you know said recruiter doesn't have a legitimate licence to employ FT's?
Can you explain about the stamps in more detail?You see,maybe there is more than one agency involved.
What makes you think FT's have been moved to avoid the police?
How do you know that the jilin Education Department has been bribed?
How do you know the bribe constitutes 1/2 a million Yuan?
Have any or indeed all of the foreign teachers been teaching there without residents' permits,or with L visas,or with F visas?What about medicals?

I'd have thought it would have been nigh impossible for you to have gotten so much detailed information about your employers' business practices,in particular about the sum of money you claim has been paid as a bribe!

Even so,an official investigation is urgently required!
