Black's Law Dictionary, Sixth Edition, p. 1025

"Nationality.  That quality or character which arises from the fact of a person's belonging to a nation or state.  Nationality determines the political status of the individual, especially with reference to allegiance; while domicile determines his civil status.  Nationality arises either by birth or by naturalization.  See also Naturalization."

Example:
