From what I have observed, once NDVO touches the file , many cases get completed in a minimum of 1 month to 4-5 months. Based on GCMS notes, it is obvious they don't do anything before the day they give IP, no background checks are initiated, nothing.
Once they pass eligibility, I don't think they do any security check, they most likely look at all the police clearance , probably checking our name against some criminal database. I don't even think they ask any external agency to check most of our files. may be they do this for few cases.
So they don't need more than a couple of months to finalize our Apps. But they take so long and screw many lives.
All they need is more human resource. I will be so happy to volunteer for free to do some clerical work. As such few of us are sitting idle
