On Monday, November 8, the United States lifted COVID-19 restrictions that kept many international travelers out of the country for 20 months, a possible indicator of the rebound of the international travel industry. As of November 8, the majority of those entering the United States will be required to show proof of vaccination as well as a negative COVID-19 test. The United States is just one of the many countries that will require proof of vaccination upon entry. Other common requirements for travel in a COVID-19 conscious world include a brief quarantine period or a negative COVID-19 test upon entry, although restrictions can vary widely by country.
