If you are a non-U.S. citizen who is a nonimmigrant (not a U.S. citizen, U.S. national, lawful permanent resident, or traveling to the United States on an immigrant visa), you will need to show proof of being fully vaccinated against COVID-19 before you travel by air to the United States from a foreign country.
As of 12:01AM ET on June 12, 2022, CDC not longer requires air passengers traveling from a foreign country to the United States to show a negative COVID-19 viral test or documentation of recovery from COVID-19 before they board their flight.
Some categories of noncitizen, nonimmigrants are excepted from this requirement. If you meet the criteria for one of these categories, you will need to fulfill additional requirements to travel by air to the United States.
The vaccine must either be approved by the US Federal Drug Administration or must have an emergency use listing from the World Health Organization (such as Astrazeneca). Mixed dose vaccinations will also be accepted. Find the complete list of accepted vaccines here, along with acceptable ways to prove vaccination.
The vaccination requirement does not apply to US citizens, lawful permanent residents or US nationals.
Wearing a mask over your nose and mouth is currently not required in indoor areas of public transportation, including on airplanes, buses, trains and other forms of public transit.
