Prediction market on metaculus. On May 27, 2026, United States Department of Homeland Security Secretary Markwayne Mullin [said on Fox News](https://abc7news.com/post/markwayne-mullin-fox-news-dhs-considering-plans-stop-customs-processing-airports-sanctuary-cities-including-sfo/19181789/) that the Trump administration is "drawing up plans" to halt Customs and Border Protection processing of international arrivals at airports in cities the administration designates as [sanctuary jurisdictions](https://time.com/article/2026/05/27/dhs-international-flight-processing-sanctuary-city-airports-mullin/). Reporting has named SFO, LAX, JFK, EWR, ORD, DEN, BOS, PHL, SEA, and [others as potential targets](https://nomadlawyer.org/airports-international-airport-dhs-sanctuary-cities-april-2026). As of the question's launch, no formal policy has been issued, and Mullin said the effort is "not initiating yet." Industry groups have [warned of major travel disruption](https://www.visaverge.com/news/dhs-weighs-cbp-pullback-at-california-sanctuary-city-airports-threatens-visa-processing/); legal challenges are widely expected if any halt is enacted; and the FIFA World Cup window in June 2026 complicates near-term implementation.
