DHS Customs Threat Adds New Uncertainty for U.S. International Travel

A renewed Department of Homeland Security threat to pull Customs and Border Protection officers from airports in so-called sanctuary cities has become one of the most consequential policy risks facing U.S. international travel just days before the 2026 FIFA World Cup begins in North America.

The idea is still a proposal, not an active shutdown order. Flights are continuing to operate, and DHS has not published a final list of airports that would be affected. But the travel industry is treating the warning seriously because CBP staffing is not a side issue at international gateways. It is the federal function that allows arriving passengers, baggage and goods to be inspected and legally admitted into the United States.

Travel Weekly reported that Homeland Security Secretary Markwayne Mullin said in a May 26 Fox News interview that the administration was drawing up plans to stop processing international flights into sanctuary cities. The Associated Press and Scripps News also reported that the proposal has alarmed airlines and travel groups, while Transportation Secretary Sean Duffy publicly pushed back on the idea of shutting down air travel because of political disputes.

Why the proposal matters for travelers

For U.S. travelers, the most important point is practical: this is not about airport amenities or a longer security line. It is about whether an international flight can be processed after it lands. CBP says its officers conduct immigration, customs and agriculture inspections for travelers seeking admission to the United States. Without that processing capacity, international arrivals at an affected airport could face cancellations, rerouting or severe delays.

The proposal has particular significance because many of the cities commonly associated with sanctuary policies are also core international travel gateways. Travel Weekly noted that the Department of Justice's earlier list of sanctuary jurisdictions included places such as Chicago, Boston, Los Angeles, New York City, Newark, Philadelphia, Seattle and San Francisco. Those markets connect American travelers to Europe, Asia, Latin America and Canada, and they also feed connecting passengers into smaller U.S. cities.

Travel groups warn of a self-inflicted hit

The U.S. Travel Association has framed the plan as an economic threat, not only an operational inconvenience. According to Travel Weekly, the group warned that pulling CBP officers from airports would cause immediate and lasting harm. It also estimated that CBP officers at Newark Liberty alone process about 5 million Americans returning to the United States each year and that the loss of international visitors entering through Newark would cost the U.S. economy about $8 billion annually.

That estimate is why the story matters beyond the New York area. Newark is both a local gateway and a connecting airport. A disruption there would affect international visitors bound for New Jersey and New York, but also families, business travelers and tour groups connecting onward to other states. The same logic applies to other major hubs that combine local international demand with domestic connections.

Scripps News, citing 2025 international aviation data, reported that the United States handled more than 1.8 million international flights carrying 259 million passengers last year. Even a partial interruption at several large gateways would therefore land inside a system that depends on tightly coordinated aircraft rotations, CBP staffing, baggage handling, crew scheduling and onward connections.

The World Cup timing raises the stakes

The timing is unusually sensitive. FIFA's official schedule shows the 2026 World Cup begins on June 11 and runs through July 19 across the United States, Mexico and Canada. The United States is preparing for a summer of concentrated international arrivals tied to matches, media operations, teams, sponsors and fans moving between host cities.

That does not mean every World Cup traveler would arrive through an airport on a sanctuary-city list. Some will use gateways such as Atlanta, Dallas-Fort Worth, Houston and Miami. But U.S. air travel is a network, and large international cities are not easily replaced. Travelers arriving for one match may connect through another hub, and airlines cannot simply shift widebody flights, customs halls, ground staff and onward domestic capacity overnight.

The proposal also comes at a time when the U.S. travel industry is already watching inbound demand closely. International visitation is important for hotels, restaurants, attractions, car rental operators, airport transfers, tour companies and convention markets. A policy fight that creates uncertainty at the border can affect trip planning even before any flight is canceled.

What travelers should do now

For now, travelers should treat the issue as a developing policy risk rather than an immediate reason to cancel plans. There is no published DHS order closing CBP processing at specific airports, and airlines have not announced mass schedule changes tied to this proposal.

Still, anyone traveling internationally through a major U.S. gateway in June or July should take a few precautions:

• Monitor airline alerts and airport flight boards before departure and again before returning to the United States.
• Keep extra connection time when arriving from abroad, especially if continuing to another U.S. city.
• Use official airline apps for rebooking options in case a return itinerary changes.
• Carry required travel documents in physical form, even if using mobile identity tools or expedited programs.
• For high-value trips, review travel insurance and supplier cancellation rules before final payment.

Travelers using affected gateway regions can also monitor Odyssey's live boards for airports such as JFK, LAX, ORD, EWR and SFO as part of a broader status check.

Bottom line for the U.S. travel market

The DHS proposal is important because it puts one of the travel system's least visible but most essential functions into the center of a national political dispute. CBP staffing is what makes international arrivals workable at U.S. airports. Removing or reducing that capacity at major gateways would not be a narrow local penalty; it would create ripple effects for airlines, returning Americans, inbound visitors, cargo, tourism businesses and World Cup logistics.

Until DHS issues a formal directive, the safest interpretation is that this remains a high-impact proposal rather than an active disruption. But for the U.S. travel market, the warning itself is already significant: confidence, capacity and predictability matter, and international travelers make plans weeks or months before they ever reach a customs hall.
