Fully vaccinated foreign nationals and returning U.S. citizens and lawful permanent residents will need to produce a negative viral test result with an acceptable testing method within one day of travel to the U.S. Acceptable testing methods include an antigen test or a nucleic acid amplification test (NAAT). Non-residents can obtain testing from private corporations, which may charge fees. Additional test sites include AdventHealth Centra Care centers, CVS Health, GuideWell Emergency Doctors, Orlando International Airport, University of Central Florida and Aventus Biolabs, Walgreens Pharmacy, and Walmart and Quest Diagnostics. Additionally, all visitors to the U.S. who are 18 or older are required to be fully vaccinated. The Centers for Disease Control and Prevention has determined that for purposes of travel to the U.S., vaccines accepted include FDA-approved and World Health Organization emergency use-listed vaccines.
