FAFSA is neutral for admission purposes. FAFSA allows any student to take a student loan and parents to take a Plus loan if they need/want. This is one reason people fill FAFSA even if they think they wonu2019t get grant aid. What you might be thinking of is the application, where you have to check if you are applying for aid.Another reason to submit is if you want to be considered for aid from the school. Most schools donu2019t care if you ask because they are need blind. They will run the numbers and offer you aid if you have need and if they want to give it to you. Some wonu2019t give it even if you have need because they only give it to the top students. Now a few schools are u2018need awareu2023 and they will consider how much you need before they feel they can admit you. If you donu2019t need a whole lot, it isnu2019t likely to affect you.So understand the policy of the school. You should probably file it and check yes for aid if there is any chance that you will get something. Even small helps. Run the Net Price Calculator to get an estimate. A few schools also require a FAFSA before they will give you a merit scholarship (most donu2019t), so read the policies on the scholarships pages/financial aid pages.
