The US has said it will reopen its borders with Mexico and Canada to fully vaccinated travellers from November.
In a statement, the Department of Homeland Security (DHS) said it will allow travel for non-essential purposes via land and ferry crossings.
From January 2022, it will also require proof of vaccination for any travel over these crossings, essential or not.
The US has restricted travel from its northern and southern neighbours since March 2020, due to the Covid pandemic.
But President Joe Biden's administration recently revealed that restrictions on fully jabbed air travellers would be eased in November.
The current rules bar entry to most non-US citizens who have been to the UK, China, India, South Africa, Iran, Brazil and a number of European countries within the last 14 days.
