After hearing nothing since February 2022, we got a huge surprise in the mail today. We got the I-751 approval letter and the 10-year green card. No interview or any RFEs needed. Yay! It was a total surprise, since we never saw it on the USPS Informed Delivery emails. What a great start to October!
We will eventually file for citizenship (N400), but it's not a priority. Good luck everyone!
