American Samoa
Unlike other U.S. territories (Guam, CNMI, Puerto Rico, U.S. Virgin Islands), American Samoa is not considered a U.S. State for the purposes of the U.S. Immigration and Nationality Act. This means that alien lawful permanent residents of the United States may be considered to have abandoned permanent residence if they have moved to live in American Samoa.
