As of Jan. 26, anyone traveling by airplane from a foreign country to the United States must get tested for COVID within 3 days before their flight departs and must present a negative test result or proof of recovering from COVID before boarding the flight.
The State Department encourages U.S. citizens to avoid non-essential travel.
If you must travel, have a plan in case you test positive. And be ready to pay additional hotel costs and change fees. Consider purchasing medical travel insurance and includes pandemic coverage.
