Agencies that sell out foreign teachers to other schools are known for not paying these teachers properly. They are outright crooks. Everywhere in China.

Your report about that couple below who got into trouble with the PSB in Shenzhen for working illegally actually confirms what I said in my previous post. I have it from first-hand sources, i.e. the chief officer of Shenzhen immigration when he controlled my new Z visa obtained in Hongkong.

Agencies such as this one get foreign teachers into trouble because of their false information given on purpose.

I generally refrain from commenting upon schools in China as there often two sides to the story. I personally never worked for Shenzhen City College but my best friend and his wife did. They were eventually picked up by the PSB for working in the country on illegal visas. They were remanded to prison for about ten days, as they did not have the money for the fine. They were deported and banned from China for five years. Their biometrics were taken so that they could not just not obtain new passports and return. Shenzhen City College just turned a blind eye to their problems, problems created by Shenzhen City College.
