I have a green card to work in America. What should I do if my China passport needs to be extended?

Passport renewal is carried out in the online booking system for overseas passport application. You can make an appointment and bring all the materials to the corresponding consulate.

The website of the Chinese embassy in the United States, such as the specific site selection materials, has relevant introductions.

The passport itself cannot be extended, and it can only be reissued (also called passport renewal). I can take the original passport with me at the appointed time.
