Just got our approval! Logged in, saw a new "Actively Reviewed", and the approval notice was under "Documents".
Hilariously the estimated time, which had been "taking longer than expected" since the summer, went back up to 4 months on the same day it was approved.
Didn't get any email about it, so definitely keep checking
Sent 1/6/23, Approval 12/7/23. Texas service center. No K3 or expedite.
Hang on friends, the next step is within reach!
