Qualifying as a Foreign Expert
In order to teach legally in China, foreigners must qualify as foreign experts. 'Foreign experts' is a term for those foreign specialist workers with special skills, who are invited to work in China to meet the needs of the Chinese economic and social development. Once approved by the departments concerned they can be employed to work in China as foreign experts.
Every province in China has a department dedicated to the management and supervision of foreign experts in their area.
Foreign experts who are invited to work in China can be classified as follows:
1. Foreign educational, scientific, cultural and medical experts.
These refer to those experts who are employed by Chinese schools and other educational establishments in such fields as publication, medicine, scientific research, culture and art, and sports. These individuals must hold a minimum of a bachelor's degree and have more than two years of 'life' experience. As such recent graduates from university may encounter some difficulty obtaining legal employment as a teacher in China.
2. Foreign economic, technical and managerial experts.
These are foreign professionals who are invited to work on either a long-term or short-term basis by Chinese government agencies, economic and social managerial departments, or by units in the fields of industry, commerce, finance, politics and law. This group includes foreign specialists sent by foreign corporations to carry out agreements between governments or international organizations, as well as those invited directly by work units to engage in technology and management.
These individuals must meet at least one of the following criteria:
* Hold at least a bachelor's degree;
* Have at least five years work experience in a relevant field and maintain trade qualifications;
* Possess particular skills needed by China;
* Have at least five years experience of working abroad in a management position of a large or medium-sized foreign enterprise or hi-tech enterprise.
3. Representatives of foreign expert organizations or resident representative offices of agencies ratified by the State Bureau of Foreign Experts Affairs of China and registered by the industrial, commercial, or administrative offices.
The State Bureau of Foreign Experts Affairs of China (SBFEAC) is the official wing of the central government charged with managing the affairs of foreign experts living and working in China. These responsibilities are further dispersed through a network of foreign affairs and foreign expert offices at a provincial level throughout China.
