im9999..that was a very good write up..
I completely agree with u and people from CSC should surely go for AOS..
AC140 is attorney certified 140 .
if ur i140 is approved and you did not notify them to forward to NVC,then u can do AC140..
i think the way it works is as follows:-
Your lawyer files for I824,but u dont have to wait till it gets approved.
With the I824 receipt you can send ur case directly to the consulate and the consulate will create a case number for you.
In India,only Bombay and Delhi are accepting AC140 cases.Chennai doesnot accept ( their whims and fancies..!!!!!!).
