Puerto Rican citizenship
On April 12, 1900, the United States Congress enacted the Foraker Act of 1900, which replaced the governing military regime in Puerto Rico with a civil form of government. Section VII of this act created a Puerto Rican citizenship for the residents "born in Puerto Rico and, therefore, subject to its jurisdiction." The Puerto Rican citizenship replaced the Spanish citizenship that Puerto Ricans held at the time in 1898. Such Puerto Rican citizenship was granted by Spain in 1897. This citizenship was reaffirmed by the United States Supreme Court in 1904 by its ruling in which denied that Puerto Ricans were United States citizens and labeled them as noncitizen nationals. In a 1914 letter of refusal to the offer of U.S. citizenship and addressed to both the President of the United States and the U.S. Congress, the Puerto Rico House of Delegates stated ""We, Porto Ricans, Spanish-Americans, of Latin soul ... are satisfied with our own beloved Porto Rican citizenship, and proud to have been born and brethren in our own motherland."" The official 1916 Report by the American colonial governor of Puerto Rico to the U.S. Secretary of War (the former name for the Department of Defense), addresses both citizenships, the Puerto Rican citizenship and United States citizenship, in the context of the issuance of passports, further evidencing that the Puerto Rican citizenship did not disappear when the Americans took over the island in 1898.
Statelessness
In 1994, Juan Mari Brás, a Puerto Rican lawyer and political historian, renounced his American citizenship before a consular agent in the United States Embassy of Venezuela. In December 1995, his loss of nationality was confirmed by the US Department of State. That same month, he requested that the Puerto Rico State Department furnish him with proof of his Puerto Rican citizenship. The request involved more than just a bureaucratic formality; Mari Brás tested the self-determination of Puerto Rico by trying to become the first Puerto Rican citizen who was not also an American citizen.
