Thanks a lot for your response in past days.
I am still very confusing on what is the "The Approval Notice“。
Can you scann your I-797 (remove your personal info) and send a copy to me: zhengda.pang@*****cglobal.net?
-----------
In all, I got three e-mails from USCIS
02/19/08: 1st e-mail: order production ordered
02/20/08: 2nd e-mail: Welcome notice sent
on 02/25/08, we received GC and the Welcome Notice (I-797C).
02/25/08: 3rd e-mail: Approval Notice sent.
But we never receive the Approval Notice. Don't know what it is.
Thanks.
