The answer hasn't changed from the last responses, Amy. And as I told you before, the only one whose opinion counts is that of the DUA. You could get every person on both boards to agree that your sister would probably get benefits, and it wouldn't matter a whit if the DUA decided otherwise. And vice versa.
I understand that you're concerned for her and that's fine. But constantly asking the same question is not going to have any affect whatsoever on the ultimate decision made by the DUA.
I wish both of you the best of luck.
