I'm an American married to a British citizen. We went down the LR1 route because we were already married when we decided to settle in America instead of Scotland. We filed outside the US

Submitted I-130 : June 14, 2021 Case Is Being Actively Reviewed : October 14, 2021

Radio silence since. Our case orginally was at the Nebraska Service center which has processing times of 3 to 7 months before being transfered to the Potomac Service center which is 12.5 to 16 months. I only found out I was transfered when I called USCIS, I didn't recieve a notice of transfer. Apparently that is happening alot. I wish you the best of luck deciding what is best for you and your fiance.
