At its core, the NTTO’s mission is to deliver accurate, timely travel data to everyone from government officials to private businesses. This summary serves as the official U.S. government source for tracking international arrivals. It breaks down the volume, key traits, and patterns of visitors arriving from various world regions and countries. Primarily, it focuses on residency—where people actually live—but it also offers insights based on citizenship.
These stats are compiled and released monthly by the NTTO, with no comparable alternatives from other federal agencies or the private sector. In a world where borders shape economies and cultures, this transparency fosters trust and informed decisions, rooted in compassion for the global movement of people.
How the Data Comes Together: The Methodology
To build this report, the NTTO weaves together data from three key government sources:
- U.S. Department of Homeland Security (DHS) and Customs and Border Protection (CBP): Their I-94 program tracks non-immigrant arrivals and departures.
- Statistics Canada’s International Travel Survey (ITS): This provides counts for Canadian residents visiting the U.S.
- Banco de México: Supplies data on Mexican travelers.
The overseas visitor count relies heavily on DHS/CBP’s Non-Immigrant I-94 records. A key shift happened in 2013 with the I-94 Automation project. Phase 1 in 2010 automated about two-thirds of records, replacing paper I-94W forms with electronic ones via the Electronic System for Travel Authorization (ESTA) for Visa Waiver Program countries. By April 30, 2013, Phase 2 automated the rest, covering visa-requiring visitors. Starting in 2014, for re
Starting in 2014, for records missing residency info, citizenship data fi lls the gap. Importantly, all I-94 data uses consistent criteria: the same visitor types and a “one night or more” stay to qualify as a traveler. Monthly releases start as preliminary, open to revisions for up to 36 months as better methods emerge—honesty in data means acknowledging it’s a living process, not set in stone.
The NTTO’s contractor receives raw I-94 data monthly from DHS/CBP. To count true visits, they filter for specific visa types that align with tourism, business, or study:
- Business Visitors: B-1 (business), WB (Visa Waiver-Business), GB/GMB (Guam Visa Waiver-Business), I/I1 (foreign media), E-1 (treaty trader), E-2 (treaty investor).
- Pleasure/Tourist Visitors: B-2 (pleasure), WT (Visa Waiver-Pleasure), GT/GMT (Guam Visa Waiver-Tourist). (Note: Excludes Cuba, code 584.)
- Students: M-1 (vocational students), MM-2 (family of vocational students), F-1 (students), F-2 (family of students).
Aligning with UN World Tourism Organization (UNWTO) standards, a visitor must stay at least one night (up to 12 months) for business, pleasure, or study. We prioritize residency for classification, but citizenship views are available too. This approach honors the human element—people aren’t just stats; they’re defined by where they call home.
For Mexicans, aggregate counts come from Banco de México’s “border travelers” (1+ night) and “tourists,” with DHS I-94 air data specifying flyers. Canadians are tallied via Statistics Canada’s survey, also revisable for up to 36 months.
A Historical Note: The Visa Waiver Program Transition
Back in 2000, the Visa Waiver Pilot Program (VWPP) expired on April 30, leading to a temporary “parole” system for eligible travelers. Parolees—allowed in for up to 90 days under similar rules—weren’t counted as tourists, as parole isn’t formal admission. It was a pragmatic bridge to avoid disrupting global travel, reflecting a compassionate response to real-world needs.
By October 30, 2000, the Visa Waiver Permanent Program Act made it offi cial, resuming WB (business) and WT (pleasure) admissions for 90 days or less without a visa for participating countries.
What’s Not Included: Non-Tourist Visitors
To keep things precise, the report excludes other I-94 categories like transit passengers, airline crews, diplomats, temporary/religious workers, and foreign media not under I visas. This focus ensures we’re tracking genuine visitors, not skewing data with unrelated entries. In essence, this summary isn’t just dry facts—it’s a window into global interconnectedness, grounded in rigorous methods.
