The U.S. is open to tourists from all countries without testing requirements but vaccination is still required for all non-US citizens/residents. The Transportation Security Administration (TSA) issued the extension of vaccine mandates that will last until April 10, 2023.
The requirements apply to any non-US citizen who will still need to provide proof of receiving at least two Covid vaccine doses or an acceptable single-dose vaccine such as the Johnson & Johnson jab.
No travel is risk-free during COVID-19. Countries may further restrict travel or bring in new rules at short notice, for example due to a new COVID-19 variant.
Foreign airlines are also required not to allow any non-US travellers who do not fulfil these vaccination rules to board their flights to the US.
Check with your travel company or airline for any transport changes which may delay your journey home.
Many airports in the USA have implemented safety measures designed to limit the spread of COVID-19. You should check the website of the airport you are flying into or transiting to see how these could affect you.
