Your post is a bit confusing. I'll present my case as a reference:
- I never added a child.
- I didn't submit PCC with application and not asked to submit it as of today. Also I believe PCC is an official document, issued by local police and might have a document no. associated with it, so what could be the reason of delay?
- I filled schedule A from age of 18 and if VO thinks there is gaps in it, they should have contacted me by now to resubmit.
In my opinion the most time taking activity might have been verification of job(s) from employers. But again most visa offices are completing the process within 12 months, so God knows how this process works ۔
