@University of Illinois

What if my parents move out of Illinois?

Once you’re admitted as a resident student, you’ll continue to qualify for in-state tuition provided you maintain continuous enrollment for the fall and spring terms and live in Illinois during that time. Returning to your parents’ home outside of Illinois for the summer only won’t jeopardize your in-state tuition.

I.e. depending on the timing of your move out of Illinois, she may be able to retain Illinois residency for tuition purposes.
