Can we save some time by ???
I think when you use AC21 it triggers some additional checks and it makes process different than same employment case. Don't know more about it.
But just for argument sake, if someone provides details such as employment confirmation, which is required before approving I-485, it can save some time. CIS officer has this information available at time of processing, so one less thing to wait for and he can continue with his process. He issues RFE if there is other thing is required, else he got everything that he requires to process this case. So, logically it saves couple of months time.
So, now if this incident is really triggered his approval than the next questions are:
1. Do they accept such information without issuing RFE ?
2. Should we provide this information, if we are in the same time frame of approvals ?
What do you think?
