No, but you do need to provide a mailing address where you can reliably receive mail. Your mailing address can be the address of a relative or friend who has given you permission to use it, or it can be your college’s address. If you find more permanent housing, you should update your address on the FAFSA.
No. If you answer “yes” to the homelessness question on the FAFSA, you will be able to submit the FAFSA without providing information about your parents because you are stating that you are not with your parents.
