In 1961, the United States imposed an economic embargo on Cuba under the Trading with the Enemy Act, which stipulates that U.S. citizens cannot spend money in foreign countries in a time of war. In 1963, the U.S. Department of the Treasury released the Cuban Assets Control Regulations, strictly outlining the permitted use of money and goods between the United States and Cuba.
U.S. citizens related to Cuban nationals via blood, marriage or adoption may travel to Cuba once every 12 months and may stay for as long as they wish.

Individuals looking to visit family members in Cuba who are not Cuban nationals or permanent residents of Cuba can also apply for a special license.
