Puerto Rico and the United States

The legal relationship between Puerto Rico and the United States has been described in a number of ways, ranging from "colonial possession" to "dual sovereigns." Technically speaking, Puerto Rico is a territory of the United States, subject to the plenary power of Congress. At the same time, however, Puerto Rico is a commonwealth with its own constitution, bicameral legislature, chief executive, and judiciary. Home to more than 4 million people, this 3,435-square-mile Caribbean island has never achieved complete sovereignty or total independence.
