<p>What if my sibling is living at home and qualifies as a “person in my parents’ household” but is not sure yet whether she is going to grad school or not?</p>
<p>I was told when my son was undecided on a grad school to just put that down, because later you need a sibling verification form, the exact school didn’t matter at the time. I would think the same thing would be with your sibling, they would want verification before the Fall semester. You need to apply to grad school in the Fall usually though, most know by the Spring if they are attending.</p>
