It is practically impossible to get instate tuition in Arizona after one year. Don't expect it if you are coming from out of state. ASU is full of law students who severed all connections to other states and they are denied instate tuition each year based on technicalities.
Worst part is for everything but tuition purposes they are residents of Arizona, which means they have nothing to show for all the work.
That is OK, there is plenty to do in the 120 degree summers in Phoenix.
I'm told about 60% don't get it and about 40% do. It is usually the dependent thing that kills people.
