A person born in Saipan becomes a citizen of which country?

Saipan is the largest and most populated island of the Northern Mariana Islands in the western Pacific Ocean. It was administered by the U.S. after World War II and became a commonwealth of the U.S. in 1978. According to the 2010 U.S. Census, Saipan's population was 48,220.

The Commonwealth's center of government is located in the village of Capitol Hill on the island. Since the entire island is organized as a single municipality, most publications term Saipan as the Commonwealth's capital. The current Mayor of Saipan is David M. Apatang, who was sworn into office on June 12, 2015.

People born there are U.S. citizens. The official currency is the U.S. dollar. As of 2009, the Northern Mariana Islands has had a representative — non-voting, like all the territories’ representatives, but still there — in the U.S. Congress.

The island is just north of Guam, south of Japan, east of the Philippines and west of Hawaii.
