Quote Sturgis on NY State free tuition requirements:
Maintain residency in the state after graduating until the number of years free tuition was received has been matched.
(2 years tuition=2 years residency after graduation)
That might be a little bit of a hitch, although being given a college degree with the stipulation it's tuition free as long as you live, (and presumably work), in New York State is a much better situation than not going to college and being able to move to any state.
What would be even better is if this law starts the ball rolling for other states to do the same thing, and then reciprocate with each other. For instance, suppose New Jersey passes the same sort of law. A certain number of college graduates in New York will find their best job prospect is in New Jersey, and a certain of new Jersey college grads will find their best job prospect is in New York. With a reciprocating agreement in place, New York grads will not be charged tuition for moving and working in New Jersey, and vice versa. So the talent pool for new college grads expands for both New York and New Jersey, and thus both states benefit.
With luck, more and more states will set up such reciprocal agreements with each other, until it becomes a national phenomenon.
