Effective January 26, the Centers for Disease Control and Prevention (CDC) will require all air passengers entering the United States to present a negative COVID-19 test (a viral detection test for SARS-CoV- 2 approved or authorized by the relevant national authority), taken within 72 hours of departure. Airlines must confirm the negative test result for all passengers before boarding. Airlines must deny boarding of passengers if they do not provide documentation of a negative test or recovery. This requirement is separate from the visa application process. All Presidential Proclamations restricting travel due to COVID-19 remain in place, and continue to apply to subject potential travelers regardless of their test results or vaccination status. Travelers holding a National Interest Exception also remain subject to all applicable pre-departure testing requirements.
