If the FAIR lawsuit is successful in over turning the Kansas law that allows illegals in-state tuition based on the 1996 federal law. That federal court ruling will then apply to every other state. This would force states that give in-state tuition to illegals to give all students the low in-state rate. The cost of this would massive.
The states effected will have to repeal their in-state for illegals law in order to charge out of state students the higher rate.
