I know this threads pretty much dead, but finally got to talk to HR about my situation last week. After 3 months of going back and forth lol... Well, I was honest with the head of HR, but as soon as I said I had originally applied with a made up SSN, he told me he'd have to let me go. I had a feeling this would happen, so it wasn't too much of a shock. Time to find a new, better job
