The USA has once again begun discussing potential restrictions on the processing of international flights at airports in cities and jurisdictions that the administration calls “sanctuary cities.” For tourists, this does not yet mean the immediate cancellation of flights, but it creates a significant risk for summer travel: if this idea becomes policy, not only individual cities but also major transit hubs through which millions of passengers enter the USA or fly further within the country could be affected.
The news broke in late May when Reuters reported that US Secretary of Homeland Security Markwayne Mullen stated that plans were being developed to cease or restrict the processing of international passengers and cargo at some major airports. According to him, a decision has not yet been made and actions have “not been initiated,” however, the idea itself is already being discussed at the administration level. The industry publication Travel Weekly also noted that Mullen repeated this position on May 26 during a Fox News broadcast, and tourism and aviation associations sharply criticized the potential move.
The main reason why this news is important specifically for tourists lies in the role of U.S. Customs and Border Protection (CBP). It is CBP officers who conduct immigration, customs, and other types of checks for international travelers upon arrival in the USA or, in the case of preclearance, before boarding a flight at some foreign airports. If an airport lacks such officers or the processing of international arrivals stops, it can affect not only passport control queues but also the very ability to accept international flights.
What Exactly is DHS Discussing
According to Reuters, Mullen said that the administration is “developing plans” to cease the processing of international travelers and cargo at major airports located in so-called sanctuary cities or jurisdictions that limit cooperation with federal immigration authorities. He emphasized that the decision has not yet been launched, but called the idea an active topic for consideration.
It is important to understand the difference between a political statement, preliminary planning, and an actual change in rules. As of May 29, 2026, there is no confirmed federal order that already stops international arrivals at a specific US airport. There is also no official list of airports to which restrictions will definitely apply. Therefore, travelers should not jump to panic conclusions, but should more closely monitor announcements from airlines, airports, and CBP.
The problem is that potentially, this is not about secondary airfields. Reuters and Travel Weekly publications mention cities and jurisdictions with large international hubs, including Boston, Denver, Philadelphia, Chicago, Los Angeles, New York, Newark, Seattle, and San Francisco. For passengers, these are not just points on a map. These are hubs through which transatlantic routes, flights from Asia, Canada, Latin America, and numerous domestic transfers across the USA pass.
Why the Tourism Industry's Reaction is So Sharp
The U.S. Travel Association told Reuters that its representatives met with Mullen, and that he confirmed previous comments about the possible withdrawal of CBP officers from international airports in certain sanctuary cities. The organization warned of “devastating consequences” for the tourism industry and communities that depend on international visitors. Airlines for America, representing major passenger and cargo airlines, also pointed to the risk of significant operational disruptions for carriers, travelers, and international cargo flows.
This reaction is explained by the fact that the international aviation market works as a network, not as a set of isolated destinations. If arrival processing is restricted, for example, in New York, it will affect not only tourists who planned to stay in the city. Some passengers arrive via JFK Airport or Newark Liberty for further flights to other states. Similar logic applies to LAX in Los Angeles, Chicago O’Hare, San Francisco International and other large hubs.
For airlines, the problem is even more complex. An international flight cannot simply be “moved” from one city to another without consequences. Slots, ground handling, available gates, crews, customs and immigration infrastructure, connections with the domestic network, and bookings for thousands of passengers are required. If restrictions affect several large hubs simultaneously, it could create a wave of rebookings and delays far beyond the specific city.
What This Could Mean for Travel to the USA
For foreign tourists, the nearest practical conclusion is this: entry rules to the USA have not changed currently due to this statement, but the political risk for flight planning has increased. If you are flying to the USA in June or July 2026, especially during the FIFA World Cup 2026, it is worth allowing for more flexibility. The World Cup already creates additional pressure on aviation, hotels, border services, and urban transport, and any uncertainty surrounding international arrivals intensifies this tension.
Passengers purchasing complex itineraries with short layovers after their first entry into the USA should be especially careful. In most cases, an international passenger undergoes border and customs procedures at the first US point of arrival, and only then continues their journey on a domestic flight. If staffing or operational restrictions arise at such a point, the risk of missing a connection increases even when the final destination is located in a completely different state.
Tourists should also distinguish between two scenarios. The first is soft: additional checks, longer queues, schedule changes, or targeted reductions in capacity. The second is hard: airlines cancel or reroute some international flights because a specific airport cannot stably process arrivals from abroad. Currently, there is no confirmation of the second scenario, but this is exactly what industry representatives fear, as it would create a systemic failure rather than a local inconvenience.
Which Airports Travelers Should Monitor
Since there is no official list of target airports, the best approach is not to guess, but to monitor those hubs that have already been mentioned in the media as potentially sensitive due to jurisdictions associated with sanctuary city policies. Such destinations mentioned in reports include New York, Newark, Los Angeles, Chicago, Boston, Denver, Philadelphia, Seattle, and San Francisco. This does not mean that all of them will be restricted, but a large part of international tourist traffic to the USA passes through them.
If your route passes through one of these hubs, it is worth checking a few things before paying for the ticket. First, whether the fare allows for free or inexpensive changes. Second, whether there is enough connection time after arriving from abroad. Third, whether there are alternative routes through other US or Canadian airports. Fourth, whether the entire trip depends on one very tight flight on the day of an important event, cruise, conference, or match.
For family trips and trips with large luggage, this is even more important. Last-minute rebooking can be more expensive and complicated if passengers are traveling as a group, have separate domestic tickets, or hotel bookings without flexible cancellation. During major events, including the World Cup, a backup plan is often cheaper than trying to fix a route after a disruption.
Why This Topic Goes Beyond Politics
Although the DHS statement is linked to US domestic politics, the consequences for tourism can be international. Large US hubs serve not only US citizens. Tourists from Europe, Canada, Latin America, and Asia, business event participants, students, families, sports fans, cruise passengers, and transit travelers travel through them. Even short-term uncertainty can influence decisions: whether to buy a ticket now or wait, choose the USA or an alternative destination, book independently or through a package operator.
For cities that host international guests, the risk is not limited to the airport. Hotels, restaurants, museums, transport companies, car rentals, the event industry, and small businesses depend on the arrival of tourists. If travelers begin to perceive entry into the country as less predictable, this can reduce demand even without formal flight cancellations.
What Tourists Should Do Now
The smartest strategy is not to cancel the trip just because of headlines, but to plan it with a larger margin. Before flying, check airline notifications, flight status, the airport page, and official CBP advice. If you are flying with a layover after an international arrival, it is better to choose a longer interval between flights, especially on peak days. If you are booking a hotel or car, choose terms that allow you to change the date without a large penalty.
Travel agents and corporate travel managers should warn clients that the situation is not yet a new rule, but is already a risk factor. For expensive routes, sports trips, and travel with fixed dates, it is worth having an alternative plan: another point of entry, an additional night before an important event, or a backup airline option. This does not guarantee the absence of problems, but it reduces the likelihood that one disruption will break the entire trip.
Conclusion
So far, the USA has not implemented a confirmed restriction on international flights at sanctuary city airports, but the very development of such plans has already become a warning signal for the tourism market. The greatest risk lies not in one specific airport, but in the potential impact on the network of international arrivals, transfers, and cargo transport. For travelers, this means simple practical advice: monitor official updates, avoid overly short layovers after entering the USA, and book summer routes with more flexibility than usual.
