Dear Karthik
I have seen files processed less than 4 months from aor.. also have seen a lot of files crossing 6 months because of the application volume.. The average timeline for applications have become 6-8 months - especially when you call CIC call center they say so.. so do not worry if you have crossed 6 months
Also if you have crossed 6 months - i would suggest ordering gcms notes - something i learned the hard way - of not ordering after 6 months..
gcms notes would give you a detailed info on the application process and will help you proactively act on any hiccups if needed - such as review required or needs more docs or missing docs..
Hope for the best - we are all here - this forum feels like family for me now - especially going through all the stress involved
Good luck
