Law of Blood(redirected from Ius Sanguinis)
Law of Blood
A citizenship law stating that all or nearly all persons born to citizens of a given state are themselves citizen of that state, regardless of where they were born. For example, one with a parent who has been a U.S. citizen for one year is a citizen of the U.S., regardless of where one was born. Some countries (including the United States) also follow the law of the soil in addition to the law of blood.
