The Internal Revenue Service classifies individuals born in American Samoa or the Commonwealth of the Northern Mariana Islands as U.S. nationals. Immihelp also explains that individuals born in foreign countries to at least one U.S. national parent are also U.S. nationals.
Immihelp explains that U.S. nationals can live anywhere within the United States. They also are eligible to apply for American citizenship and obtain passports but are not permitted to vote or hold elected office. U.S. nationals must pledge their sole allegiances to the United States regardless of whether they are citizens or non-citizens, according to the Internal Revenue Service.
