Finally, there is an update on my case today! Case status changed to New Card Is Being Produced. Took them exactly 12.5 months as per the current WAC case processing time posted on USCIS. I am excited and relieved! Glad I held off on filing the N-400, feeling that it would have delayed things a bit. Anyway, now I have to wait until I receive the card in my hand. I filed AR-11 for address change earlier this year. Let's see if USCIS sends the card to the right address. USPS messed up the mail delivery last time and returned the card to USCIS. Took me another 3 months to get USCIS to resend it. I'll watch my mailbox like a hawk.
