Hello guys i am an English-Chinese teacher as one colleague has just advice you,you shouldn't take the fly-by- night massengers in the name of visa service.These guys are mostly based in Shanghai,Guangzhou and Nanchang.Believe me or not they if not foreigners,conive with foreigners to freeze your account,money and your lagal staus in China if at all you have one.I have collgues who are foreign teacher who were in the same school happy working but now are fraustrated beggers bc they've not been working for months because of visa related problems scammed by their foreign collegues.Some of them are migrant workers bc of this issue.Some do not even have places to pass their nights becase of either police the land lords.As anadvice i will recommend that a foreign teacher should not have anything doing with passport posting to another city or he should wait until when the visa is done and confirmed by the immigratio then can he pay the money.Remember... scammers are more godly than God himself.I'm a christian i hate cheating and i know how difficultit is to live in a foreign country like China .....my country.Beware and be wise because my school and collegues have lost an inspirational guy to scammers.
