Visitors to the USA Require Negative COVID-19 Test Result
The US Centers for Disease Control and Prevention (CDC) announced it would require all air passengers entering the USA beginning January 26, 2021, to present a negative COVID-19 test, taken within 72 hours of departure.
On January 12, 2021, the CDC's announcement stated, 'Airlines must confirm the negative test result for all passengers before boarding. And airlines must deny boarding of passengers if they do not provide documentation of a negative test or recovery before entering the USA.
And the CDC stated, 'foreign governments may implement travel restrictions with little notice, even in destinations that were previously low risk. If you choose to travel internationally, your trip may be disrupted, and could be difficult to travel back to the USA.'
