Hi, all! Just adding more info for those looking for mail timelines
We sent our package in on 4/11 and it was received by 4/14 at 6AM, so we definitely knew they got it (scary since my card expires 5/3). But Informed Delivery shows that I have 2 letters coming tomorrow! One of them (I read through the envelope window) is about them reusing my biometrics, but the other I am not sure. I'm guessing it's the NOA1 and extension letter?
So, 13 days from the date I mailed it out!
