The new testing rules for visitors to the US will come into effect from Monday 6 December, the Foreign Office has confirmed.

On Thursday evening, the White House announced it was narrowing the testing window for international visitors to within 24 hours of departure, down from 72 hours.  

The FCDO has updated its advice to say: “From 6 December 2021, before boarding a flight to the USA, all passengers – regardless of vaccination status – are required to show a negative COVID-19 test result taken no more than one day before travel. All air passengers to the USA are also required to provide contact information to their airlines before boarding.

“You should check with your airline before you travel for more details. Full requirements for pre-travel testing can be found on the CDC website.

“Children under 2 years old do not need to test.”
