I think first they will approve I485J. later 485

If u get approve of i485j Uscis will send you receipt notice I think so.

Yeah, but is it possible they approve I485 before I485J?

Yes, usually that's the sequence, first 485J later 485 if you're lucky. In my case they didn't approve 485 yet, they changed 485 status to case must be reviewed.

How much time gap did you have between I485J and I485 approvals?

my 485j got approved almost a 2 months ago.

@God only knows. Did you get the receipt notice of 485j approval how long does it take to approve.

Got both I485 and I485J approved today👏🏻

congratulations 🎉
