Visa history of Russia
From 6 April 2001, the United States required transit visas for flights through US airspace to third countries. In response, Russia introduced similar transit-visa requirements for citizens of the United States who transit Russia to third countries, from May 6, 2001. On 19 June 2001, after a meeting between presidents Putin and Bush, the transit visa requirements were mutually canceled. In 2003, the United States Secretary of Homeland Security suspended two programs, Transit Without Visa (TWOV) and International-To-International (ITI), that allowed entry without a visa. Visa-free transit through the territory of the United States was denied, including through airports - there is no transit zone. For US citizens in transit through Russia, it is also necessary to have a 72-hour transit visa, in case they intend to leave the transit area of an airport.
