After obtaining a permanent residence permit in China, it is usually not necessary to renew the original work permit.
Foreigners’ permanent residence permit, also known as the “Chinese green card”, is a certificate of unlimited duration of residence for foreigners in China. Foreigners who obtain the permit do not need to apply for a work permit for employment in China.
But if foreigners want to enjoy more convenience in work and other aspects (such as salary purchase and payment convenience), they can also choose to apply for a work permit.
