Sadly, there's nothing under USCIS Notices so far. But the status says "Case Was Received And A Receipt Notice Was Sent." I guess, we really have to wait for the notice to appear on the Documents tab.
Hi @earthbi! We're also going through the same thing and just submitted the I-130 online. All we got after submitting was an email with the payment details and a case number.
Is this the one you attached to the I-485 that you mailed? Or is it I-797 (at least that's what I've been seeing online)?
