Jus sanguinis is a Latin legal term that means "Law of Blood." It means that a person automatically is awarded the nationality of his or her parents upon birth. Thus if an American couple have a baby, that baby is automatically an American national, merely by his or her parents being Americans. Combined with "Jus soli," a baby can possibly be born with dual citizenship. An example would be a baby born to an American couple in Spain, the baby would be an American National due to his or her parents being Americans, but also a Spanish National due to being born in Spain.
