As long as she doesn’t give up her Texas residency, she remains a Texas residency. For instance in our case, my daughter was an Illinois resident when she applied to colleges. She goes to UT-Austin. Because UT wants to and encourages their students to gain residency and will help them to do so, she became a Texas resident. So, she had to give up her Illinois residency and is now only a Texas resident. The huge perk is that her annual tuition is now only about 13k a year vs the 46k her tuition would be (last year the savings were about $30k, this year it’ll be the $33k). She just applied for UT’s iMPA program and was accepted. Since she is currently a resident she remains a resident when she does her 5th year, even though she won’t begin that for 2 more years. If she wants to apply to a public university in Illinois for anything, she will have to come back here and give up her Texas residency.
My son will be attending University of Michigan. He will not be giving up his Illinois residency so regardless of if and when he wants to go to grad school, he’ll always be an Illinois residency, until he establishes permanent residency somewhere else.
