The processing time for extending the residence permit may vary depending on the region, specific circumstances, and the number of applications at that time.
Generally speaking, it may take around 7 to 15 working days under normal circumstances. But in some busy areas or special circumstances, the processing time may be extended.
For example, in some first tier cities, due to the large number of applications, it may take 15 working days or even longer. In some areas with relatively low application volumes, it may take around 7 working days to complete the processing.
To avoid unnecessary trouble caused by the expiration of your residence permit, it is recommended that you plan ahead and apply for an extension.
