Thanks for clarifying that @Bsch4477 . I try to stress clarity on the support issue. If you'll take note, the support requirement is on the student, and only the student. Even what you cited on page 21 makes no mention of parental support one way or the other.
I see a number of post from parents where they question if they can claim the student since they did not provide more than half of the student's support. So it has to be clarified that there is absolutely no requirement what-so-ever for the parent to provide a single penny of support to the student. The support requirement is on the student, and only the student.
While not impossible and not unheard of, it is rare for an undergraduate to provide more than half of their own support. Especially if they're not married and a full time student.
