Puerto Rico

Puerto Rico is a freely associated commonwealth of the United States, composed of one large island and several small islands. Puerto Rico is bordered on the north by the Atlantic Ocean, on the east by the Virgin Passage (which separates it from the Virgin Islands), on the south by the Caribbean Sea, and on the west by the Mona Passage (which separates it from the Dominican Republic). San Juan is the capital of Puerto Rico, as well as its largest city.
