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.
Puerto Ricans in World War II
Puerto Rico was annexed by the United States in accordance to the terms of the Treaty of Paris of 1898, ratified on December 10, 1898, as consequence of the Spanish–American War. U.S. Citizenship was imposed upon Puerto Ricans as a result of the 1917 Jones-Shafroth Act (the Puerto Rican House of Delegates rejected US citizenship) and were expected to serve in the military. When an Imperial Japanese Navy carrier fleet launched an unexpected attack on Pearl Harbor on December 7, 1941, Puerto Ricans were required to bear arms in defense of the United States. During World War II, it is estimated by the Department of Defense that 65,034 Puerto Ricans served in the U.S. military. Most of the soldiers from the island served in either the 65th Infantry Regiment or the Puerto Rico National Guard. As the induction of Puerto Ricans into the armed forces increased many were assigned to units in the Panama Canal Zone and the British West Indies to replace the continental troops serving in regular Army units. Those who resided in the mainland of the United States were assigned to regular units of the military. They were often subject to the racial discrimination that was widespread in the United States at the time.
