USPS status issue... did it get delivered?

[Heather&Kevin 25]

I mailed my i751 (tracked and signed for USPS) last week - guaranteed delivery was meant to be Monday Dec 10th

 

Should I be worried?  It appears to have not been delivered - but the zipcode mentioned (85036) is the correct uscis zipcode.  So does this mean it is there and just in the system???   Any ideas??

 

USPS tracking says...

 

All sorting has been completed at the delivery unit for today's deliveries at 10:00 am on December 8, 2018 in PHOENIX, AZ 85036.

Status:  In-Transit

I would guess it has more to do with a PO Box address.

USCIS
P.O. BOX 21200
Phoenix, AZ 85036

 

That "box" may be huge mail hampers. You chose for it to be signed for. To a street address where the doorbell rings and the missus answers and signs is one thing. But in a postal building mail hamper, there isn't likely a little USCIS person sitting inside and signing for things. So Saturday was the last scan. Eventually Monday, the guy from USCIS  mailroom picks up bags of mail. Just a scenario in my head, but I could see why a signed for delivery in this case might get stuck in the tracking system and actually be in a sack over at USCIS.

Thank you!   You actually gave me a much calmer day by saying that   :O)     And I am overjoyed to report that I just got my text message saying USCIS have it.    Which is a relief... as my GC expires today - at midnight.    :)    USPS is still showing 'in transit'.     Will be interesting to see if I ever get the USPS delivery receipt in the mail.   Thanks again!

Yes, I have a similar question...i got confirmation that my i-751 was delivered but it only tells me it was delivered to Phoenix Arizona with the zipcode 85036. How do I know it actually went to the USCIS address at PO Box 21200? Can I call the USCIS building there to confirm they got my package?
