Ok, first of all, it's great that people want to come and visit China; however, unless they are involved in materials science/industrial research and cutting edge mil/tech, i dont think they should be allowed any long term residential visa; at best, they can have a 3 month Schengen type visa if their country has good relations with China for eg Serbia but they should not be taking jobs that should be going to Chinese people. In order of preference, it should be PRC citizens which includes SAR citizens like HK and Macau and Taiwan Compatriots, then foreign wives of Chinese men (notice i specifically said foreign wives and women?).
