HipRock, Yes it was the same thing in my status online. I talked to my lawyer today and he told me they had wrong address for the lawyers office and he is going to call them to fix that up. That was the reason why the mail was returned to the sender and the USCIS re-mailed it to my employers office. They also sent me the "change of address" mail along with my reciept which was dated 14th of May.

So, at this point, according to what I have experienced, I'd suggest you check with your employer if they have received the receipt. I know how hellish it could be. I have just been there.

Thanks.
