Funding for the Department of Homeland Security (DHS) will expire at 12 am on Saturday, February 14th. The shutdown comes as a result of disagreements over restrictions for current federal immigration operations. 

This shutdown will not affect all branches of the government, though workers serving under the DHS could see lapsed paychecks if the shutdown persists. A key concern is the impact the shutdown will have on the TSA, as the historic shutdown in late 2025 led to several flight cancelations.
