Question: When did Manuel Guzman's country of citizenship become an American territory?

full_context: Document 1: Spanish West Indies: The islands that later became the Spanish West Indies were the focus of the voyages of the Spanish expedition of Christopher Columbus in America. Largely due to the familiarity that Spaniards gained from Columbus's voyages, the islands were also the first lands to be permanently colonized by Spanish in the Americas. The Spanish West Indies were also the most enduring part of Spain's American Empire, only being surrendered in 1898 at the end of the Spanish–American War. For over three centuries, Spain controlled a network of ports in the Caribbean including Havana (Cuba), San Juan (Puerto Rico), Cartagena de Indias (Colombia), Veracruz (Mexico), and Portobelo, Panama, which were connected by galleon routes.
Document 2: Puerto Rico: Originally populated by the indigenous Taíno people, the island was claimed in 1493 by Christopher Columbus for Spain during his second voyage. Later it endured invasion attempts from the French, Dutch, and British. Four centuries of Spanish colonial government influenced the island's cultural landscapes with waves of African slaves, Canarian, and Andalusian settlers. In the Spanish Empire, Puerto Rico played a secondary, but strategic role when compared to wealthier colonies like Peru and the mainland parts of New Spain. Spain's distant administrative control continued up to the end of the 19th century, helping to produce a distinctive creole Hispanic culture and language that combined elements from the Native Americans, Africans, and Iberians. In 1898, following the Spanish -- American War, the United States acquired Puerto Rico under the terms of the Treaty of Paris.

Document 9: History of Puerto Rico: Located in the northeastern Caribbean, Puerto Rico formed a key part of the Spanish Empire from the early years of the exploration, conquest and colonization of the New World. The island was a major military post during many wars between Spain and other European powers for control of the region in the 16th, 17th and 18th centuries. The smallest of the Greater Antilles, Puerto Rico was a stepping - stone in the passage from Europe to Cuba, Mexico, Central America, and the northern territories of South America. Throughout most of the 19th century until the conclusion of the Spanish -- American War, Puerto Rico and Cuba were the last two Spanish colonies in the New World; they served as Spain's final outposts in a strategy to regain control of the American continents. Realizing that it was in danger of losing its two remaining Caribbean territories, the Spanish Crown revived the Royal Decree of Graces of 1815. The decree was printed in Spanish, English and French in order to attract Europeans, with the hope that the independence movements would lose their popularity and strength with the arrival of new settlers. Free land was offered to those who wanted to populate the islands on the condition that they swear their loyalty to the Spanish Crown and allegiance to the Roman Catholic Church.
