I have no idea if it went into security screening. We got additional doc request thrice. It would have been helpful if everything came together.
In August last year we were asked to submit Voter ID, Adhaar.
In January this year we were asked to submit my Birth certificate, secondary school certificates, early school certificates, voter ID, Adhaar as proof of sponsoring parents and PCCs
And then again in Feb this year we were asked for my Dad's explanation of government service document, PCCs
FYI, I haven't been able to track my parents application as it says application not found, so I don't know what's going on.
But one thing that's different is that since end of Jan, I've been getting quick response on documents (within a 3-4 days) from IRCC Mississauga. So I'm assuming that my current agent is quick. Hoping to see quick processing of application from now onwards now that I've submitted.
