The reason why I said it's possible to have flood of approvals soon is back in March, when TPS deadline expired, approvals came in every day. That trend continued for three months. Then in June, back to slow mode. I figured out BCIS is playing three to four months(a quarter) by three/four months tricks, three months for one type of case, three months for another. Since the deadline of religious workers cases is 9/30, we'll see positive changes beginning from Oct. For the nearby furture, it should be brighter.
And they certainly won't let a case sitting there for 2 years. That's way too long. There have been lawsuits against them for delaying cases over 2 years. They don't like lawsuits.
CSC back in July has announced Oct the month they will restart employment cases. NSC did same thing. And recent AILA meeting repeated the same date. That's why I mark Oct 1 down.
75% 485 adjudicators will be back, you calculate the speed. Normally, if you run 100 cases, you should expect to see 10 approvals per day. That's considered normal. And that's what happened in Mar/Apr/May, when most of Nov/Dec cases got approved.
