Airline

We just received notice today that our case was transferred to Vermont. As the petitioner, I have never had any criminal activity other than a couple speeding tickets (eight years ago). My job required background checks a few years ago and my landlord ran one on me a year ago, before I moved in. I just completed a background check on myself to make sure there weren't any false flags, but nothing came up there either. Our NOA 1 was received Oct 18, 2022, so only about 3 months ago. Could this be a wave of transfers to load level between centers? Is it normal for cases to be "reviewed" and transferred so quickly?
