Can Indonesian apply work Permit in Indonesia Embassy base in Kuala Lumpur?

Mr Simone, you can try to renew your work permit inside PRC. Actually, if you won’t change your job, you can just renew your residence permit at the exit and entry administration of the local public security bureau. The required documents include your passport, valid registration form of temporary stay permit, the application form, a half-length color photo, the employment contract, and your work permit as well as other materials the consular officers consider necessary.
You cannot renew the work permit at Indonesia embassy, but should apply for a new work Z type from Chinese embassy if you exit to Malaysia.
