Hi mom, sorry for the slightly late reply to your post. As per the last piece of advice you gave me (which you were absolutely right about, of course), I've been taking some "time off" from obsessing about the green card, since I was definitely getting excessively worried about things for no reason (which I know must have been a pain to read!) and I had wanted to wait until I had some solid news to tell you guys one way or the other. Due to the issues I had in the interview (where my IO refused to accept my I-134 and repeatedly insisted that I needed an I-864 instead, even though he was of course wrong on this) I admit that my worry level about another mistake being made was much higher than it should have been when I saw that one of the "steps" in the DV timeline just did not happen.
Today (9/9/2015) however, I received my physical green card in the mail
Strangely, I received no status updates that it was even sent (my USCIS site still says welcome letter, and I got no e-mails/texts) - I just checked my mailbox and saw an unexpected priority mail envelope, and had no idea it was the green card until I opened it. I actually left it on my counter for some time before opening it as there's no mention of USCIS at all on the envelope (they use an unnamed PO box in Lee's Summit as the return address for some reason) so I had no idea it would be something so important!
Just to give a little bit more information, as perhaps it may be helpful in the future to other people: my USCIS status was only updated twice, and only two updates show up in my history - one for the fingerprint fee (way back in June), and one saying that my welcome letter has been sent (in August), both with corresponding e-mail alerts. There were no other updates - no CPO, no card sent notice, no tracking number, and no delivery confirmation.
From googling around about normal AOS cases, as well from the DV timeline spreadsheet, this definitely feels non-typical and most cases seem to get all (or at least most) of those notices, so I'm not sure what caused this. It's maybe worth mentioning that the card took 3 full weeks to the day from the welcome letter date to come, which is the maximum estimate given in the welcome letter (I had originally planned to call USCIS tomorrow in fact to follow up because of this). Perhaps its possible that my IO had forgotten to order card production initially, but that this was fixed internally at a later date (which would gel with some non-DV experiences I had read where updates were missing). Either way, I don't want to speculate too much, and I'll make a final update to my timeline entry in the spreadsheet later tonight.
Thank you guys (and of course,
@Sm1smom in particular) so much!! After a half decade or so of entering the lottery with admittedly with very little expectation of winning, it's been an amazing ride to get selected this year, and have things finally completed. This thread has been amazing, and I don't know what I would have done without it - I'm so glad almost all of the cases I've been following over the past few months have completed successfully, and I really wish the best of luck to everyone else who is still trying to get things done.
