The Department of Homeland Security, International Visitor Arrivals program (DHS I-94 Form) provides the U.S. government and the public with the official monthly and annual overseas visitor arrivals to the United States. The National Travel and Tourism Office (NTTO) manages the program in cooperation with the Department of Homeland Security, Customs and Border Protection (CBP). Data are reported in a monthly publication, “Summary of International Travel to the United States” that highlights overseas visitor arrivals by country of residence, port of entry, mode of transportation, type of visa, and more. Canadian and Mexican arrival data are sourced from Stats Canada and Banco de Mexico, respectively.
