This is precisely why I refused to start looking for a job until I'd got the EAD card in hand, despite various members of my wife's family asking me loaded questions like "so when
are you going to start looking for a job?"
anyway, i guess my point is that letting a job slip through your fingers isn't the end of the world. You're probably resigned to it by now. you know the score. Just look forward to the feeling of having that EAD card between your fingers, it so feels like the world is your oyster!

by the way, it took me less than a week to find a kick ### job after getting the card. this really is the land of opportunity
