He stuck around for an entire year and did everything that was asked of him. If the university decides not to let him in an possibly stringing him along this whole time, really doesn't look that good.
Has he done anything wrong since then? He was banned from the University
for one year. If they weren't going to allow him back, ban him for life. I find it hard to believe he would have stuck around, instead of attending school closer to home, without some kind of commitment from the school. Then again, we know how the Administration handles commitments.
