You were almost lucky haha, it was in Nebraska and with K3 it would have processed within 4-6 months in Nebraska SC , I have been doing so much research and saw very quick approvals from Nebraska with K3 and also on USCIS website processing times for K3 at Nebraska shows 4 months however Vermont I think is more than I-130 processing times.
Mine is at Potomac and it’s the slowest and seems like Potomac does process in chronological order so no hope at all however lately I have seen some very few quick approvals(6-7 months) at Vermont SC for those who have filed K3 so there is some hope for you, otherwise Vermont processing time is worst of all SC.
They have committed to improve for quicker decisions for FY2023 and new goal is to process within 6 months that’s the only hope I have otherwise we will be waiting for 1 years of just I-130 approval looking at last year trend and another 2 months at NVC and then don’t know how long wait for visa appointments at embassy so roughly 1.5-1.8 years to complete everything sadly
