In a series of Acts, the United States conveyed nationality upon outlying territories not destined for statehood. Inhabitants became neither aliens, eligible for naturalization, nor citizens with full rights. In 1900, legislation defined inhabitants in Puerto Rico as both citizens of Puerto Rico and U.S. nationals. Also that year, the Palmyra Atoll was separated from Hawaii and extended benefits of the Constitution. In 1902, similar legislation to that passed for Puerto Rico came in to force concerning the Philippines. The United States established special rules for people working in the Panama Canal Zone in 1903, under the terms of the Panamanian-U.S. Canal Convention. Under its provisions, the was modified to include language that persons born in the Canal Zone or in Panama itself, on or after February 26, 1904, to a parent who was, or formerly was, a United States national derived U.S. birthright citizenship. In 1906, Congress passed legislation to allow persons born in unincorporated territories to be naturalized, under special provisions.
