The Centers for Disease Control and Prevention (CDC) does not require that international travelers undergo mandatory federal quarantine, but does recommend travelers get tested 3-5 days after travel AND stay home or otherwise self-quarantine for 7 days after travel.
CDC has provided guidance to state and local public health officials in the United States to use their authorities to protect the health, safety, and welfare of persons within their jurisdictions. CDC will continue to work closely with state and local public health officials in the United States to control the spread of COVID-19. Prior to traveling, please check for quarantine guidelines in the state and city you will be visiting or transiting for recommendations or requirements related to travel.
All travelers to the United States should continue to monitor the CDC website for testing and quarantine requirements, including state and local regulations related to travel.
