The Trump administration is considering suspending immigration checks at some major US airports.

The President's Administration Donald Trump prepares plans to suspend federal immigration and customs procedures at airports located in "sanctuary cities," which the White House accuses of not cooperating sufficiently with federal immigration policy.

US Homeland Security Secretary Markwayne Mullin confirmed that discussions were underway within the administration, while specifying that no final decision had yet been made.

In an interview with Fox News, Mullin stated that the government was considering ceasing to process international travelers and cargo in certain major cities run by Democrats. He argued that these jurisdictions would prevent federal authorities from "enforcing federal immigration laws."

Such a measure could have major consequences for international air traffic and US commerce, as the United States prepares to welcome millions of foreign visitors for the start of the 2026 FIFA World Cup next month.

The cities concerned would include several major American airport hubs, notably Boston, Chicago, Denver and Philadelphia, according to a list recently published by the US Department of Justice concerning so-called "sanctuary" jurisdictions.

Last week, Reuters reported that Markwayne Mullin had privately discussed this possibility with representatives of the transport and tourism sector, raising serious concerns among airlines and economic players.

Sanctuary cities generally limit their cooperation with federal authorities regarding the deportation of undocumented migrants. This issue has become a major point of contention between the Trump administration and several Democratic states and municipalities.

If implemented, this measure would mark a major escalation in the political standoff over immigration in the United States, with potentially significant repercussions for international travel and the American economy.
