Rambo-
Thanks for the update.
If the original labor has a I-140 approved, a application to revoke/withdraw that I-140 petition has to be applied with the new I-140. Iam not sure what happens if this is not done.
I guess it basically depends upon the case officer that handles your case and his expertise in this matter. According to my lawyer, if the case goes in the hands of a temp, than there are chances of getting more RFE's, it is i guess just a matter of luck, Get ready and hold your breath before you throw your dices!!!.
Guys if you have a pending I-140 please update the list, so that we can atleast have a trend. Iam sure that there are many people in EB3, who have not updated the list.
-Thanks.
