How is Puerto Rico related to the US?

Answer 1

On July 25, 1898, during the Spanish-American War, Puerto Rico was invaded by the United States with a landing at Guánica. As an outcome of the war, Spain ceded Puerto Rico, along with Cuba, the Philippines, and Guam to the U.S. under the Treaty of Paris. It is now a U.S. territory. There are no travel restrictions to other US areas and no customs duties or quotas on shipments between Puerto Rico and the US Mainland. Products manufactured in Puerto Rico are "Made in the USA". The people of Puerto Rico do not vote in national elections. They are represented in Congress by a Resident Commissioner who has a voice in the House of Representatives but no vote. Most federal taxes are not levied in Puerto Rico. No federal income tac is collected from island residents on ordinary income, except in cases of Federal employees.
