U.S. citizenship is usually acquired by birth when a child is born in the territory of the United States. In addition to U.S. states, this includes the District of Columbia, Guam, Puerto Rico, the Northern Mariana Islands and the U.S. Virgin Islands. Citizenship, however, was not specified in the original Constitution. In 1868, the Fourteenth Amendment specifically defined persons who were either born or naturalized in the United States and subject to its jurisdiction as citizens. All babies born in the United States--except those born to enemy aliens in wartime or the children of foreign diplomats--enjoy U.S. citizenship under the Supreme Court's long-standing interpretation of the Fourteenth Amendment. The amendment states: ''All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.'' There remains dispute as to who is ''subject to the jurisdiction'' of the United States at birth.

What's the best answer to this question: is a naturalized citizen the same as a us citizen?
yes
