The Centers for Disease Control and Prevention says home COVID-19 tests are now acceptable for people flying internationally into the U.S.
The guidance page, which was updated Friday, says a self-test can be used if it meets the following criteria (from the CDC website):
If there is a positive test, the telehealth provider is asked to provide the results to local public health authorities and to advise the traveler not to fly until they complete isolation or quarantine subject to local requirements.
This guidance is only for people coming into the U.S. from another country. Requirements for traveling from the U.S. to an international destination may differ, based on that country’s guidance.
