Hello, I'm a new member (Dec 2022 Filer) that has been following various case processing threads/google docs for several weeks now. Really appreciate the daily scanning and result compilation many members are doing, I can't imagine waiting for months up to years without having the general knowledge of cases being processed each month. There's a lot of well analyzed results of opened cases by members such as @mw & rg k1 and discussions backed by many google sheets analysis in @AndiB and @Anna Hessler's thread. However, I've been having hard time finding information about our current backlog estimate.
It seems like our current backlog estimate of various filers ranges from 38k ~ 55k and USCIS quarterly report does not seem to completely match with these numbers either. I'm wondering if anyone has data on monthly change in backlog in order to forecast the expected month NOA2?
I hope to find out info such as the following:
Total backlog for each month (Sept 2021 - Jan 2023)
Backlog Delta each month = Backlog of pervious month + Total new filers this month - Number of cases closed per month (Accepted/Denied/Withdraw)
Apologies in advance if my question does not make sense or had already been answered in other threads, I don't seem to be able to find a general consensus about the current backlog estimate.
