GC application status

I mailed out I-130 and I-485 concurrently using USPS, all paper applications. For online status check I have to provide a 13-character case number (identifier), but how would I be notified about that number? In the mail? or via email? When am I supposed to receive that -- a week from the mailing date?

• If I file I130 online, may I USPS mail in I485 right after? -syn- ♀ (89 bytes) () 03/05/2024 postreply 20:43:49

• 你的I-485要附上I-130收据，但是我相信你可以从网上马上印出I-130收据 -newacct- ♂ (0 bytes) () 03/05/2024 postreply 21:45:50
