Trump Administration Exploring Plan to Halt Immigration Processing at Sea-Tac and Other Sanctuary City Airports

Seattle-Tacoma International Airport could face significant disruption under a proposal being reviewed by the Trump administration that would halt immigration and customs processing at airports in cities designated as sanctuary jurisdictions, according to a report from Reuters.

Seattle is among the cities being considered under the plan, which Homeland Security Secretary Markwayne Mullin confirmed is still being explored. No final decision has been announced, and no operational changes have been made at Sea-Tac. However, the prospect of reduced or suspended customs processing at one of the West Coast’s busiest international airports has drawn immediate concern from airline and travel industry groups, who warn the move could create serious disruptions for travelers, carriers, and international cargo operations.

The timing of the proposal is drawing particular attention in Seattle. The region is weeks away from hosting six FIFA World Cup matches, with hundreds of thousands of international visitors expected to pass through Sea-Tac between June and July. Any disruption to international arrivals processing during that period would compound an already complex logistical picture for the airport, airlines, and regional tourism infrastructure.

The Port of Seattle, which owns and operates Sea-Tac, has previously stated its commitment to treating all arriving passengers with dignity and fairness, and has emphasized that customs and border processing at the airport is controlled exclusively by federal authorities rather than the port itself.

Washington state and Seattle city officials have not yet issued formal responses to the Reuters report. If the administration moves forward with the proposal, it would likely face immediate legal challenges from affected jurisdictions, several of which have standing court orders limiting federal use of local infrastructure for immigration enforcement purposes.

The proposal remains under review.
