In the process of getting Police Clearance Certificates in China, we have seen various of digital copies, such as scan copies by scanners, or photos by cameras.
We list the types of invalid digital copies for China PCC application.
1. Photo by Camera
These photos are ok for evaluation, but invalid for application.
2. Scanned by CamScanner
We don't have samples to show, but PDF by CamScanner is invalid for your China Police Clearance Certificate application.
Paid version and Free version are both useless for your China PCC application.
3. Altered or adjusted by Photoshop
The scan copy should not be altered or adjusted by any software, the samples below were created by PDF software when the client found out the scanner produce JPEG scan copy. Those are considered as invalid documents.
4. Foreign Visa and stamp pages
The foreign visa has nothing to do with China, and the foreign stamp can not prove the day you got in or left China.
So don't waste your time and money on scanning those pages.
