Hey everyone, I have an approved I-140 with PD-Sep2012 from my previous employer (A). I am about to join employer A next month in a similar but different role. How similar must the new job be for me to use the existing 140 and not have to go through perm/140 again with A? Given that I may be able to file I-485 in November if USCIS accepts DOF chart, I'm trying to see what options I have at this point.
