Beginning November 8, a new policy on international air travel will begin. Restrictions for more than 30 countries, including China, India, Brazil and most of Europe will allow foreign nationals back into the United States, with proof of vaccination and a negative COVID test within 3 days of travel. Those who are un-vaccinated may still enter the United States with proof of a negative COVID test within 24 hours of flying. Detailed information can be found on the U.S. State Department website.
