Why bother with all the trouble? Just take the Beijing job if you really want to stay in China. Or marry a Chinese woman for a visa. You will get a one year RP. Tell her you will give here 3000 or 4000 rmb a year to renew. Then you can just do private tuition

You will make a lot more than at any college with little stress. I am serious, I know several guys who have done this. The PSB even told them it's the way to go.
