The waiting time for foreigners to extend their visas is usually about 7-15 working days, but the actual waiting time may vary due to the following factors:
1. Work efficiency of the application location: There are differences in the workflow and efficiency of immigration management departments in different regions.
2. The completeness and accuracy of application materials: Incomplete or incorrect materials may result in extended approval time.
3. Number of applicants: If it is during the peak application period, the processing time may increase accordingly.
For example, in some economically developed cities with more foreigners, it may take about 15 working days due to the large number of applications; In some areas with fewer foreigners, the approval may be completed in about 7 working days.
For specific waiting times, it is recommended to consult the local immigration management department.
