The U.S. Department of Homeland Security (DHS) is currently considering a significant policy shift that would cease customs processing services at airports situated in sanctuary cities. This move, under review as of late May 2026, would affect how international arrivals are handled at these designated airports.
Should this proposal advance, it could lead to disruptions in international flight operations. Airlines might face the need to cancel or reroute international flights originally scheduled to land at these airports, which could result in delays and complications for inbound travelers.
