There is at least one judicial district for each state, the District of Columbia, and Puerto Rico. The territories (insular areas) of Guam, the Northern Mariana Islands, and the United States Virgin Islands each have one territorial court; these courts are called "district courts" and exercise the same jurisdiction as district courts, but differ from district courts in that territorial courts are Article IV courts, with judges who serve ten-year terms rather than the lifetime tenure of judges of Article III courts, such as the district court judges. American Samoa does not have a district court or a federal territorial court, and so federal matters there are sent to either the District of Columbia or Hawaii.
