International travellers will have to get tested before travelling by air into the United States (US), or be prepared to show proof of a recent positive viral test and a letter from your healthcare provider or a public health official stating that they were cleared to travel.
On January 12, 2021, CDC issued an Order requiring all air passengers arriving to the US from a foreign country to get tested no more than 3 days before their flight departs and to provide proof of the negative result or documentation of having recovered from COVID-19 to the airline before boarding the flight. This Order will go into effect on January 26, 2021.
