Card Returned Undeliverable

[Mfcba 0]

Hi guys, hope this can help someone. My online case status said 

my GC returned to Immigretion. I checked the case status online and it said “ card is being returned to USCIS because undelivered “ . The next day I called post office they told me the post office where my card is located. I went there right when they opened and asked, they told me they are 100% sure it was back to the original sender at that time. I kept on calling the post office and begged them to look for it, stout 4:00pm one of the supervisor looked for it so hard and found it for me. 

my thoughts for you guys is, after approval, keep on checking your status online, and if it is for some reason returned, don’t stope contacting your local post office until you get it or until the trucking told you it is somewhere else other that your local office. I heard i takes forever to get your GC after it returned back.

good luck to everyone!
