notice of action for i-140 concurrent filing

[rmjb]

Hi,
We did a concurrent filing of 140/485/765 and got the receipts (i-797c) for the 485 and 765. However, no such receipt has arrived for i-140 itself, and it's been a week now since we got the receipts of the others. Shouldn't we have received the i-797c for the i-140 by now?
Thanks.

Apparently, when they cash the checks, the SRC# is marked at the back. So, now I have the SRC# and see that the case is pending, and it says that the notice was mailed quite a while ago.
Do they send it to the residential address or to the employer address (the case is filed on behalf of the employer, in our case.)
Thanks.
