From OOS resident to in-state resident - core residency questionnaire

Hello
Brief background: son accepted to UT, currently out of state but father is Texas resident (we are divorced). Has anyone filled the questionnaire and been successful with this residency change?

In going through the residency questionnaire, Section E says that student has been claimed as a dependent or is eligible to be claimed as a dependent by the Texas resident parent. now , my interpretation is that my son is eligible (from this point forward) to be claimed by his father therefore he can be considered a TX resident.

Any thoughts? Experiences?
Appreciate the help - thanks

Well, you have to answer all of the questions about his father in section G.8.

My experience is that the people in the residency office are very helpful and would be happy to talk to you. They answered lots of my questions with no hesitation. They don’t bite!

(My son got residency before they tightened up the rules a few years back.)
