Hey
I actually saw this many months ago. What I understand is that back in 2017 and 2018, there were many prolonged SS cases that went beyond 12- 18 months. From 2019, SS has been speeded up and an increasing number of cases can be finalized within 5-8 months. There are always some super long cases that exceed 18 months, but I believe they only make up a tiny proportion of all the SS cases. Since this petition is particularly about delayed cases, we surely can see a crazily high density of super slow cases here, but it doesn't mean they are common.
By now I have completed 5 months of SS. If my SS can be finalized within 7-8 months, then I will still have 2-3 months' waiting to do, and I can now mentally accept this scenario. Since my case has already gone beyond 6 months, I don't have any high expectations anymore.
You don't need to be scared at all at this point because you don't know if you have been or will be sent for SS.
