The US is reopening its borders today to double-jabbed foreign visitors, ending a 20-month entry ban.
The ban was imposed by former President Donald Trump due to Covid-19.
It has affected non-US citizens from over 30 countries, including the UK and EU states, separating families and stalling tourism.
Airlines are expecting a flood of visitors as the restrictions are lifted for those who are fully vaccinated, and undergo testing and contact tracing.
In an effort to stop the spread of coronavirus, US borders were initially closed to travellers from China in early 2020. The restrictions were then extended to other countries.
The rules barred entry to most non-US citizens who had been in the UK and a number of other European countries, as well as China, India, South Africa, Iran and Brazil.
Under the new rules, foreign travellers will need to show proof of vaccination before flying, get a negative Covid-19 test result within three days of travelling, and hand over their contact information. They will not have to quarantine.
The US land borders with neighbours Canada and Mexico will also reopen for the fully vaccinated.
