Sept 2022 filer as well out of Florida.
I actually used to live in Virginia, so I know where the PSC is in an area of Alexandria called "Crystal City". I guess they call it the PSC since it's close to the Potomac River and DC.
Not a large building by US Government standards. It's medium sized, large enough to be noticeable though...but likely not enough to house the numbers needed to process all the filers. I've been to three USCIS buildings in the Virginia area.
Hope they transfer some applications as it seems the Potomac officer is getting overwhelmed.
Also keep in mind the Federal workforce is *unfortunately* facing a mass exodus of employees. They're hitting a huge wave of retirees and there are record resignations. I don't know how it's affecting DHS and USCIS but I'm sure they're hit with it. The USG and parts of it were largely not ready for remote work. Lots of Govn't agencies are behind on the technical curve.
