California residency question

I’m asking on behalf of a relative: If a student is attending a UC as an instate resident, is their residency status affected if the parents move out of state? I assume they’re fine, but I don’t know the specific rules. Thanks

It seems that as long as the student is continuously enrolled on a full-time basis, CA residence continues.
