@USCIS I can't get ahold of anyone either via message or phone. You say you've mailed my green card out but it's not arrived and @USPS has no idea where it is. The tracking number is a dead end. I would think you'd be concerned about this. I am.
@USPS I haven't gotten mail in 10 weeks- since I put a change of address. And 3 tickets later, not a word, not a call. Approaching 30 min of being on hold with local office. HELP.
