NEW REASON OF REJECTION !
I have come across a new reason of rejection, and I think it is of a fundamental importance for all of us to consider.
The Reason:
Somebody got rejected with comments of expired passport attached. The affectee stated that he/she has attached a valid passport, but the pages were only visible in Foxit reader, while Adobe Reader DC could not render those pages !
The visa officer must have tried to open the passport attachment using Adobe Reader which is very normal and could not see the scanned passport pages. They must have appeared blank, hence the rejection. The affectee must have played with the foxit printer settings to make it view in certain versions (may be to reduce file size) and ended up with rejection.
The Lesson:
Always double check with the Adobe Reader if documents open successfully. Adobe Reader is recommended by CIC visa offices, as they use Adobe to secure and virtually sign document. I am saying this because there visitor visa applications are secured to be viewed on Adobe Readers and get validation within adobe. They also recommend to use the latest version. I will get some time to make a video of scanning and which digital printer to be used in order to make sure the files open everywhere.
Good Luck Everyone !
