Apply for her again, she has a "different living situation" which may change things. Also, when she turns 18, she will have to apply again on her own. If she is applying for SSI, be careful how you describe things. If you are giving her "free rent" or buying her food, they will calculate that as money she has coming in, and reduce her SSI accordingly. There is a balance with "what's fair", and what is a gift. My son had not been paying me anything, because he couldn't work, but I told them I would charge him $250 in rent, and 1/2 utilities when he did have money, and he got the full SSI.
