The Department of Homeland Security announced the extension “based on the success of the existing restrictions and the emergence of additional global COVID-19 hotspots”. Chad Wolf, acting secretary of Homeland Security, said in a statement: “This extension protects Americans while keeping essential trade and travel flowing as we reopen the American economy.”
The measure applies to all nonessential travel, therefore essential travel such as work and study, critical infrastructure support, economic services and supply chains, health, immediate medical care, safety and security, and trade will still be permitted. Americans who are returning to the U.S. are exempted from the border closures.
