What are the consequences of an employer's refusal to issue a certificate of separation to an expatriate employee?

Approval by the administrative department. The subject of the application for approval is the new employer, and the approval documents include, but are not limited to, the certificate of separation and the cancellation slip of the Foreigner's Work Permit, which are issued by the original employer. If the original employer does not cooperate in the issuance of these documents, the foreign employee will not be able to change his/her work permit and will not be able to legally participate in labor in China. The foreign employee can solve the problem through complaints or lawsuits, and the enterprise will bear the losses caused.
