considering the historical facts, wait letterer's will either receive updatd doc request or MR or both together.
Assuming option 1 -> MR then how much time it takes to receive visa after you submit the MR?
Assuming option 2 -> Update docs only -> how much time it will take to receive visa after submit update docs & later MR.
Assuming option 3 -> both -> how much time ?
Assuming it takes 3 months max considering all above option, then in view of 3 years theory after doc sent, I must receive one of the above request near the completion of 33rd month. I have completed 28 months so I should not expect anything in near 5 months period.
are my calculations fine ??
