In 1986, for the first time China granted a German the permanent resident permit, which was looked upon as China's first "Green Card" for foreigners.

In 1991, four foreigners got the certificate from the Tianjin Public Security Bureau for their outstanding contribution to Tianjin's economic development.

By the end of 2001, China had devised a plan to regulate a "Green Card" system. Subsequently, major cities including Beijing, Shanghai and Guangzhou issued related regulations.

The Law of the People's Republic of China on Control of the Entry and Exit of Foreigners was adopted by the Standing Committee of the People's Congress in November 1985.

The Enforcement Regulations on Law of the People's Republic of China on Control of the Entry and Exit of Foreigners revised in July 1994.
