I guess there will be more and more people reporting the same "good" news.
got 485 receipt in mail yesterday (08/14)
Package delieverd on 7/2 9:01am to NSC
140 NIW is still pending in NSC...
Bank of America online infomation shows all checks were cashed, including:
$395 (485)
$180 (EAD)
$170 (AP)
Just be a bit patience. I know it's been hard for myself but what else can we do? A friend of mine (NIW 140 proved long time ago, package delievered on 7/2 9:30am) got her 458 receipt last week when only scarce good news was posted here. My point is that you will get it soon, maybe very soon... depending on your package delivering date and USCIS efficiency.
Wish you guys the best luck, but I don't think it is a matter of luck. Your receiving the receipt is a pretty much guaranteed fact! If you didn't do anything terribly wrong when filling those forms, you will get the receipt soon!
