I need to change visa X to work permit

Hi, if you want to convert the X type into a Z type to work in China, it's possible to do that within China. First, you should prepare the relevant documents including your passport and its copy, the application form, a passport-style photo, valid registration form of temporary residence, work permit as well as other requirements. You can ask your employer to get the work permit for you Then, submit the application to the local PSB.
