Puerto Rican citizenship
A 1918 official report from the American colonial governor of Puerto Rico to the U.S. Secretary of War, this one after the Jones Act of 1917, had become law, states that the "passports...[are used to] prove a person's nationality," thus making clear that Puerto Rican citizenship and Puerto Rican nationality were one and the same. The United States government also recognizes this status in its own records. For example, the CIA World Fact Book, states that the nationality of Puerto Ricans is not "American" but, in fact, ""Puerto Rican"." The Spanish Government also recognizes Puerto Ricans as a people with Puerto Rican, "and not American," citizenship. It also provides Puerto Rican citizens privileges not provided to citizens of several other nations, such as Haití, Jamaica, Trinidad y Tobago y Guyana. Since 2007, the Government of Puerto Rico has been issuing "Certificates of Puerto Rican Citizenship" to anyone born in Puerto Rico or born outside of Puerto Rico with at least one parent who was born in Puerto Rico.
Insular Cases
In 1898, the United States signed the Treaty of Paris (entered into force April 11, 1899), which ended the Spanish–American War and granted the United States the Philippines, Puerto Rico, and Guam. Additionally, Cuba remained under the jurisdiction of the United States Military Government until its independence on May 20, 1902. Since there was nothing in the United States Constitution about governing newly acquired territories, the government used the guideline from Title IX of the Treaty of Paris. Those that were born in Spain but living in one of the territories, peninsulares, “could retain their Spanish citizenship,” or even eventually have the option to become United States citizens. Title IX of the Treaty of Paris did not grant the same rights to the indigenous population. Edguardo Melendez writes, “Puerto Ricans and Filipinos-- ‘the natives of the islands’-- not only remained colonial subjects but became stateless peoples too: they were denied the right to keep their Spanish citizenship, as well as their right to become U.S. citizens.”
