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.

The Federal government did not quite know how to classify Puerto Ricans at first. In 1904, the Immigration Service implemented more strict regulations that classified people from Puerto Rico as aliens who tried to enter the US, although previously they had easily migrated. In a case carried to the US Supreme Court by Isabel González in 1904, the court ruled that Puerto Ricans had the right of free travel to the US. In 1917, the US granted full US citizenship to residents of Puerto Rico; they were restricted from voting in presidential elections because they did not have the status of a state.
