While all U.S. citizens are U.S. nationals, not every U.S. national is a U.S
. citizen. Very few fall into the category of non-citizen U.S. national as
defined in the Immigration and Nationality Act. Currently, only those born
or with ties to the outlying U.S. possessions of American Samoa and Swains
Island are born as non-citizen United States nationals. The same applies for
those born outside of these possessions but born to one or more non-citizen
national parent as long as a residency requirement is met.
