A person who has entered the State of Mississippi from another state and enters an educational institution is considered a nonresident. Even though he may have been legally adopted by a resident of Mississippi, or may have been a qualified voter, or a landowner, or may otherwise have sought to establish legal residence, except as otherwise provided in Section 37-103-25(2), such a person will still be considered as being a nonresident of Mississippi if he has entered this state for the purpose of enrolling in an educational institution.
