considered integral parts of the country are the District of Columbia, the federal
district where the capital, Washington, is located; and Palmyra Atoll, an
uninhabited but incorporated territory in the Pacific Ocean. The United States also
possesses five major overseas territories: Puerto Rico and the United States Virgin
Islands in the Caribbean; and American Samoa, Guam, and the Northern Mariana
Islands in the Pacific. Those born in the major territories (except for American
Samoa) possess U.S. citizenship. American citizens residing in the territories have
many of the same rights and responsibilities as citizens residing in the states;
however, they are generally exempt from federal income tax, may not vote for
president, and have only nonvoting representation in the U.S. Congress.
