Question: When did the country Luis Villafane is from become a commonwealth of the United States?

full_context: Document 1: 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.
Document 2: 51st state: Puerto Rico is designated in its constitution as the "Commonwealth of Puerto Rico". The Constitution of Puerto Rico which became effective in 1952 adopted the name of Estado Libre Asociado (literally translated as "Free Associated State"), officially translated into English as Commonwealth, for its body politic. The island is under the jurisdiction of the Territorial Clause of the U.S. Constitution, which has led to doubts about the finality of the Commonwealth status for Puerto Rico. In addition, all people born in Puerto Rico become citizens of the U.S. at birth (under provisions of the Jones–Shafroth Act in 1917), but citizens residing in Puerto Rico cannot vote for president nor for full members of either house of Congress. Statehood would grant island residents full voting rights at the Federal level. The Puerto Rico Democracy Act (H.R. 2499) was approved on April 29, 2010, by the United States House of Representatives 223–169, but was not approved by the Senate before the end of the 111th Congress. It would have provided for a federally sanctioned self-determination process for the people of Puerto Rico. This act would provide for referendums to be held in Puerto Rico to determine the island's ultimate political status. It had also been introduced in 2007.
Document 3: Puerto Rico: In 1950, the U.S. Congress granted Puerto Ricans the right to organize a constitutional convention via a referendum that gave them the option of voting their preference, ``yes ''or`` no'', on a proposed U.S. law that would organize Puerto Rico as a ``commonwealth ''that would continue United States sovereignty over Puerto Rico and its people. Puerto Rico's electorate expressed its support for this measure in 1951 with a second referendum to ratify the constitution. The Constitution of Puerto Rico was formally adopted on July 3, 1952. The Constitutional Convention specified the name by which the body politic would be known.
