British officials were taken by surprise on Monday when the US announced its decision to enable fully vaccinated people into the US from November.
The ban on travellers from the UK has been in force since March 2020 when the pandemic began gathering pace.
The current rules bar entry to most non-US citizens who have been in the UK and a number of other European countries, China, India, South Africa, Iran and Brazil within the last 14 days.
Under the new rules, foreign travellers will need to demonstrate proof of vaccination before flying, obtain a negative COVID-19 test result within three days of travelling, and provide their contact information.
These fully vaccinated individuals will not be required to quarantine.
Boris Johnson had been expected to push for the US to reconsider the travel ban in the country in his meeting with President Biden this week.
