You pay in-state tuition rates at North Carolina schools even if you are not a resident. Every North Carolina National Guard member is charged in-state tuition whatever state they live in, and active duty members assigned to a North Carolina installation under orders get in-state rates for themselves and their dependents. If you are reassigned out of the state, you and your dependents keep the in-state rate as long as you stay continuously enrolled in the same program.
