Nationals are entitled to live and work in a country and have many–but not all–of the rights of citizens. For example, a person can obtain a US passport as an American Samoan. Still, he is not automatically a citizen of the US (at least one parent must be a citizen for him to be automatically a US citizen too). He can work in the US as a national, but he cannot vote in local, state, or federal elections, and other restrictions apply.
