What do Biden's new travel restrictions mean for you?

Your last day of vacation abroad could be a lot less relaxing under President Joe Biden's new COVID-19 safety protocols for travelers entering the U.S.

The more restrictive measures were announced Thursday, as the Omicron variant of COVID-19, which was recently detected in the U.S., stirs up fears of another nasty wave of the virus. 

Starting next week, all travelers entering the U.S., regardless of their vaccination status or nationality, must provide proof of a negative COVID-19 test within one calendar day of their departing flight. Previously, a negative test administered up to three days before boarding a flight was considered valid. Biden has also extended the current rule mandating mask-wearing on airplanes, trains, buses and at airports — scheduled to expire in January — through mid-March.
