Foreigners usually get a 30 day stay visa after cancelling their work visa.
During this period, if foreigners find new job opportunities, they can apply for re employment of work permit and extension of residence permit. If they haven’t found a new job or don’t plan to continue working in China, they can use this time to leave China. If, for some reasons, it is impossible to leave the country within the validity period of the stay visa, foreigners can apply for a new stay permit.
As for how many times a stay visa can be handled, it usually depends on the specific situation and needs of foreigners and whether they meet the application conditions. Each application requires submission of corresponding materials in accordance with relevant regulations and requirements, and approval by the exit and entry management agency of the public security organs. It should be noted that each application may require new proof materials and reasonable explanations to explain why an extension of stay is necessary.
