jiang...but u can work p-time job then, right? In China , u cant.

@Tigertiger: this ranking is not for Green Card, but specifically for work permit holders.

I was under the impression professional expats in China have always been ranked and categorized. This system is merely a much needed evolution from an earlier archaic and somewhat subjective system.

Whether the evolution is an improvement remains to be seen, but it definitely appears more "scientific" than its predecessor. As with all evolutionary systems, we should expect some growing pains on the road to sustainability and stability.
