On the day you filed the FAFSA, with which parent did you live with the most for the 365 days prior? If you had lived with neither, and you had an issue that day in being a dependent at all, you should not have filed as such. You filed using your father’s info which he had to have given you, without a thought about these things. Then you got your EFC, and it became problematic and you are looking for a way retrospectively to change the situation. That is unlikely to fly.
That maybe you did not know that you had any choice about filing as an independent student even as you were sitting there THAT Day You filed FAFSA, having supported self completely and totally, fearing becoming homeless if YOU can’t pay your own bills, might be viewed as an accidental and automatic pick of using your father’s info.
Do understand that the fact that your parents won’t/can’t pay for you, that you can’t do it Is not a valid reason and is directly addressed in the guidelines. Doesn’t matter. You want exception made by Fin aid advisor because you have been totally self sufficient to point of edge of homelessness. That is a possible reason.
Do read the rules on being an Independent Student for FAFSA very carefully.
