please ignore above posting. I did double check my
I-797C welcome notice which was sent to me directly from uscis. I-797 which is original 485 approve notice (even though uscis put "welcome notice" was sent to my attorney and I haven't still gotten it yet.
I see now. thanks to 485pending4yrs for your input. Those who hired lawyer to file 485s should check with your attorney asking for ORIGINAL 485 approval notice which is a very important document - the only LPR (Lawful Permanent Resident) proof when your GC gets lost.
