Although Medals of Honor can be awarded only to members of the U.S. armed forces, being a U.S. citizen is not a prerequisite for eligibility to receive the medal. Since the American Civil War, hundreds of people born outside the United States have received the medal, the most recent of these recipients being Pedro Cano and Jesus S. Duran who received their medals in March 2014 for actions performed during World War II and the Vietnam War respectively. The large number of foreign-born recipients during the 19th and early 20th centuries was mostly due to immigration waves from Europe.
