It is nice that they decreased the processing time by one month. It was 23 and now it is 22 months.
I think that has happened because recently they gave DMs to many people who are still in their first year.
Even some 2019 applicants get their DMs. I saw a guy here who got DM in his 8th month or a guy without sending his PCC.
I am happy for them. I hope they don't give these early DMs to balance processing time. I hope this decrement will continue.
When I sent my files to IRCC in December 2018, processing time was increased from 17 to 18 months.
Besides, as I mentioned before, the federal quota levels will increase around %10 in 2020.
This may decrease the processing time to 20 months by itself.
Btw, I started to see the percentage of remaining estimated processing time, that's another thing that they've implemented.
