Tufan,
No theory works it seems!!! I am also in the same situation like you and losing a lot in my careers because of 485. My client wants to hire me to they have been waiting more than a month as they have already shortlisted couple of other people for that position. It really sucks!!!!!
Rajaa,
I don't think, You need to go for IEAD as one of my friend worked after the EAD expired and IEAD got denied. His lawyer spoke with VSC and they told that he is authorized to work as waiting for EAD Renewal.
