After 12 months of ZERO updates, we finally got something today! (Thank you USPS Informed Delivery.) As soon as I saw there was a letter arriving, I logged into myUSCIS to check for the update. But... There wasn't an update, just the same old ones.
Anyway, the mail finally came, and we rushed to open the letter. No update really. It was another NOA that my husband's green card has been extended for an additional 24 months. (48 months total now) That's it. I guess that's better than an RFE, so we'll take it.
My husband just said he'd consider citizenship, so we maybe doing that in the next year or so. It's not a priority for us.
