This is a FAFSA4caster question.
Select your parents’ current state or country of legal residence. Select Foreign Country if your parents’ legal residence is in a foreign country.
Residency (domicile) is your parents’ true, fixed, and permanent home. If your parents are residing in a state for the sole purpose of attending a school, do not count that state as their legal residence. If your parents are separated or divorced, use the state or country of legal residence for the parent whose information is reported on the FAFSA4caster.
Each state determines legal residency differently.
If your legal parents (biological and / or adoptive) have different states of legal residence, answer for the parent that you lived with most during the last 12 months. If you did not live with one parent more than the other, provide information about the parent who provided more financial support during the last 12 months, or during the most recent year that you actually received support from a parent.
A legal parent includes a biological or adoptive parent, or a person that the state has determined to be your parent (for example, when a state allows another person’s name to be listed as a parent on a birth certificate). Grandparents, foster parents, legal guardians, older brothers or sisters, widowed stepparents, and aunts and uncles are not considered parents unless they have legally adopted you.
