Entry rules in response to coronavirus (COVID-19)
Entry to USA
It is not possible for most British nationals to enter the USA if they have been in the UK, Ireland, Schengen zone, Iran, Brazil, China, South Africa or India within the previous 14 days. On 20 September 2021 the US Government announced it would lift travel restrictions starting in November for foreign citizens who are fully vaccinated against COVID-19. We are waiting for further details. British nationals planning to travel to the US from November 2021 onwards should wait for further information to be released by the US Government. We will update Travel Advice concerning entry to USA accordingly.
Those arriving from outside the above areas will need to get a visa or an Electronic System for Travel Authorisation (ESTA) visa waiver to enter or transit the USA as a visitor. You should consult the US State Department website to determine which you will need.
US citizens and permanent residents of the USA, certain specified close family members and certain other limited categories of visas holders (such as UN staff and diplomats) are exempt. They will still be able to enter the USA, subject to normal entry requirements. Further details are on the US Embassy Website.
The US Centers for Disease Control and Prevention (CDC) requires that all air passengers arriving to the US from a foreign country get a COVID test no more than 3 days before their flight departs and present a negative result or provide documentation of having recovered from COVID-19 in the past three months to the airline before boarding the flight. If you are fully vaccinated with an FDA-authorized vaccine or a vaccine authorised for emergency use by the World Health Organisation, you should also get a viral test 3 to 5 days after travel. Unvaccinated people should get tested with a viral test 3 to 5 days after travel and self-quarantine for a full 7 days after travel. Those who have recovered from a documented COVID-19 infection within the last 3 months, should follow all requirements and recommendations for fully vaccinated travellers, except you are not required to get a test unless you are symptomatic. In addition, everyone should follow all state and local guidelines. More details are on the US Centers for Disease Control and Prevention website.
On 21 January 2021 President Biden signed an Executive Order requiring masks to be worn on aircraft, trains, buses and at airports.
