The Biden administration is taking the first steps toward requiring nearly all foreign visitors to the U.S. to be vaccinated for the coronavirus, a White House official said.
The requirement would come as part of the administration's phased approach to easing travel restrictions for foreign citizens to the country.
No timeline has yet been determined, as interagency working groups study how and when to safely move toward resuming normal travel.
Eventually all foreign citizens entering the country, with some limited exceptions, are expected to need to be vaccinated against COVID-19 to enter the U.S.
The official spoke on the condition of anonymity Wednesday to preview the policy under development.
