Pending approval of my I-751, I sent in my N400 application online on September 9th. I was eligible to apply as early as August 5th. Received NOA and Biometrics Reuse online the following day, September 10th. And true enough, my I-751 as well as that of my K2 had some movements thereafter (VJ estimate was at May 2024 mark before I sent in my N400 application). Please find my timeline below for reference:
