The Secretary of Homeland Security has decided to continue temporary travel restrictions at land ports of entry between the United States and Mexico due to the COVID-19 pandemic. These restrictions limit travel to "essential travel" only, which includes returning U.S. citizens, medical travel, educational travel, work-related travel, and certain other categories. The goal is to reduce the risk of spreading COVID-19 and protect public health. These limitations do not affect air, freight rail, or sea travel but do apply to passenger rail and ferry travel, and they will be in effect from January 22, 2021, to February 21, 2021.
Simple Explanation
The United States is keeping its border with Mexico mostly closed, allowing only important travel like going to work or school, or returning home, to help stop the spread of COVID-19 from January 22 to February 21, 2021.
