Some updates in march, case approved. I updated the timeline by my signature, but these are the relevant events:
03/02/2022 → Interview scheduled. Notice coming in the mail soon.
03/17/2022 → I-130 Approved! Noa in the mail two days later.
03/31/2022 → Interview day and I-485 Card produced by the time we were leaving.
04/01/2022 → Case approved
04/04/2022 → NOA Case Approved arrived in the mail.
Waiting on green card!
I was able to translate for my parent.
Because I filed I-130 online and it was separate (still concurrent), it got approved before the interview.
They requested my original birth certificate and translation during the interview. I had that ready.
