Green card processes are also not without caveats these days. Every visa extensions with or without I140s can be subjected to "administrative reviews" that can take anywhere from a month to six months. That's what the original post refers to. Lot of folks around HN have no clue about how the Trump administration has wedged a bureaucratic block at every stage of the work visa process. I am also pretty well settled in the US but will be moving to Toronto to get rid of this visa nightmare.
