Starting January 26, all travelers must have a negative Covid Test to enter, dated within 3 days of entering the United States of America.
Information for Travelers Returning to the United States: Effective January 26, the Centers for Disease Control and Prevention (CDC) will require all air passengers entering the United States (including U.S. citizens and Legal Permanent Residents) to present a negative COVID-19 test, taken within three calendar days of departure, or proof of recovery from the virus within the last 90 days. Airlines must confirm the negative test result or proof of recent recovery for all passengers prior to boarding. Airlines must deny boarding of passengers who do not provide documentation of a negative test or recovery. Please see CDC’s FAQ for answers to questions about the new requirement for proof of negative COVID-19 test or recovery from COVID-19 for all air passengers arriving in the United States. If you are planning to travel overseas or if you are currently overseas and planning to return to the U.S., you should contact your airline for specific information about testing requirements for travelers. Because airlines may adopt and modify their own specific policies to implement CDC’s new rule, you should contact the carrier for your U.S.-bound flight and not rely on information from other carriers or information or experience from previous trips. The Department of State advises all U.S. citizens to read the country-specific Travel Advisories and U.S. Embassy COVID pages for updates on the impact of COVID-19 worldwide. U.S. Embassy COVID pages will provide updated information on the availability of testing in the countries they serve.
