Everyone has a MITTIMUS, that is his sentencing papers and either he or you could get one through the County Clerks Office here in Illinois and he through the law library once he gets to his parent prison.
He will get credit for any county time after he was taken in after sentencing. If he spent 7 days in county prior to being moved to IDOC, he will get credit for that time.
He will be able to take classes/programs once he gets to his parent prison and signs up for them. There are long waiting lines sometimes, but I am sure there will be something he can take, his Bachelor's Degree doesn't matter.
He has to do 5 years, he could get some extra time off if he qualifies for classes/programs and also if he is eligible for the new *sentence credit* once it starts up, it's the NEW good time program and if he qualifies for that, he could get an additional six months off (not guaranteed).
If he lived with you in Maine before his arrest here, he maybe able to apply for something called Interstate Compact to come back there and do his parole. It all depends on if you would sponsor him and they (Maine) would allow it. There are restrictions he would have to meet for this. You can look into our Interstate Compact board here on IPT for more information.
