<p>This is a school by school thing, and as far as I know, there no single collected database which lists such benefits. There are small handful of schools in which out-of-state tuition waivers are given, my own medical school does this and usually OOS students have to pay out of state tuition for a single year (at most). Some people know about it coming in and so get all 4 years taken care of. From my classmates, there are claims of a few other schools that have similar setups, but I’ve never taken the time to look further or confirm these second and third hand rumors.</p>
