An executive order signed by newly inaugurated U.S. President Joe Biden, which requires international travelers entering the United States by air to show proof of a negative covid-19 test within 72 hours of departure, was enacted on Jan. 26, creating a host of new requirements for travelers to fulfill before boarding their flight. 

Vacationers need to make sure they are obtaining the right type of test for their travel plans, since certain types of tests, like serological tests and antibody tests, are not considered acceptable proof to enter the United States. Make sure to take a PCR test or an antigen test instead, which detect active infections through a nasal swab, with several testing options available in the Mexico City area. 

The U.S. Embassy in Mexico has also released a list of facilities throughout the country for travelers requiring testing outside of the capital.

Travelers must also be sure to obtain their test results within 72 hours of departure, at the latest, otherwise their test results will not be accepted as valid.

Tourists should also check the time frame that laboratories deliver results within, which varies from place to place, to make sure test results are received in time for embarkment.

If the 72-hour window expires due to a flight delay, be aware that passengers will have to take the test another time around.

Test results must be accompanied by a signed and witnessed disclosure form, which should be provided for travelers at testing laboratories, and can also be downloaded by travelers from the U.S. Centers for Disease Control and Prevention (CDC) website.

All children over the age of two will be required to provide a negative test as well, though infants will be spared from the process, and parents can present testimony for all minors traveling with them rather than necessitating another CDC disclosure form.

Biden’s executive order on Thursday, Jan. 21, requires all international travelers to quarantine upon arrival in the United States, but the exact terms of the isolation have not yet been announced. As of now, the CDC recommends for international travelers to quarantine for seven days after arriving.

The same executive order requires travelers to wear a mask at all times within airports and on airplanes, as well as on buses and trains within the United States.
