Which travellers require a transit visa/permission and which officially documented exemptions are important?
Travellers in immediate and continuous transit through the U.S. generally need a transit (C) visa; holders of a valid visitor (B) visa may be able to transit on it, and citizens of Visa Waiver Program countries may be able to transit under that programme. Transit to/from the UN Headquarters District requires a C-2 visa.
