Puerto Rico

Puerto Ricans are by law citizens of the United States and may move freely between the island and the mainland. As it is not a state, Puerto Rico does not have a vote in the United States Congress, which governs the territory with full jurisdiction under the Puerto Rico Federal Relations Act of 1950. However, Puerto Rico does have one non-voting member of the House called a Resident Commissioner. As residents of a U.S. territory, American citizens in Puerto Rico are disenfranchised at the national level and do not vote for president and vice president of the United States, and do not pay federal income tax on Puerto Rican income. Like other territories and the District of Columbia, Puerto Rico does not have U.S. senators. Congress approved a local constitution in 1952, allowing U.S. citizens on the territory to elect a governor. A 2012 referendum showed a majority (54% of those who voted) disagreed with ``the present form of territorial status''. A second question asking about a new model, had full statehood the preferred option among those who voted for a change of status, although a significant number of people did not answer the second question of the referendum. A fifth referendum was held on June 11, 2017, with ``Statehood'' and ``Independence/Free Association'' initially as the only available choices. At the recommendation of the Department of Justice, an option for the ``current territorial status'' was added. The referendum showed an overwhelming support for statehood, with 97.18% voting for it, although the voter turnout had a historically low figure of only 22.99% of the registered voters casting their ballots.
