For the region within an animal brain sometimes known as "insular area", see
Insular cortex.An insular area is
United States territory that is neither a part of one of the
fifty states nor a part of the
District of Columbia, the nation's
federal district.Because those insular areas that are inhabited are unincorporated territories, their native-born inhabitants are not constitutionally entitled to
United States citizenship under the
Citizenship Clause. However, Congress has extended citizenship rights to all inhabited territories with the exception of
American Samoa, and these citizens may vote and run for office in any U.S. jurisdiction in which they are resident. Residents of American Samoa are
U.S. nationals, but not U.S. citizens; they are free to move around and seek employment within the whole United States without immigration restrictions, but cannot vote or hold office outside of American Samoa.
