Puerto Rican citizenship
In 1994, Puerto Rican activist Juan Mari Brás flew to Venezuela and renounced his US citizenship before a consular agent in the US Embassy in Caracas. Mari Brás, through his renunciation of U.S. citizenship, sought to redefine Section VII as a source of law that recognized a Puerto Rican nationality separate from that of the United States. In December 1995, his denaturalization was confirmed by the US State Department. Among the arguments that ensued over his action was whether he would now be able to vote in elections in Puerto Rico. On November 18, 1997, the Supreme Court of Puerto Rico through its ruling in "Miriam J. Ramirez de Ferrer v. Juan Mari Brás" reaffirmed the Puerto Rican citizenship by ruling that U.S. citizenship was not a requirement to vote in Puerto Rico. According to the court's majority opinion, the Puerto Rican citizenship is recognized several times in the Puerto Rican constitution including section 5 of article III, section 3 of article IV, and section 9 of article V. In a 2006 memorandum, the Secretary of Justice of Puerto Rico concluded, based on the Mari Brás case, that the Puerto Rican citizenship is "separate and different" from the United States citizenship.
Puerto Ricans in the United States
According to the 2010 US census, of the stateside Puerto Rican population, about 53.1% self-identified as white, about 8.7% self-identified as black, about 0.9% as American Indian, about 0.5% as Asian, and 36.7% as mixed or other. Though over half self-identified as white, the Puerto Rican population is largely made up of multi-racials, most Puerto Ricans are mixed to varying degrees, usually of white European/North African, black West African, and indigenous Taino ancestry. The average genomewide individual ancestry proportions have been estimated as 56% European, 28% West African, and 16% Native American. However, there are significant numbers of (pure or nearly pure) blacks and whites within the Puerto Rican population as well. Historically, under Spanish and American rule, Puerto Rico underwent a whitening process, in particular, the island had laws like the "Regla del Sacar", in which people of mixed-race origin were identified as "white", the opposite of the one-drop rule in the United States.
