The proclamation, issued by President Donald Trump on December 31, 2020, extends previous suspensions on the entry of certain immigrants and nonimmigrants into the United States. These measures are meant to protect the U.S. labor market during the economic recovery from the COVID-19 pandemic. The extensions affect Proclamation 10014 regarding immigrant visas and Proclamation 10052 concerning certain nonimmigrant visas, and both will now expire on March 31, 2021, with possibilities for further continuation. The proclamation includes severability and general provisions to maintain its enforceability and compatibility with existing laws.
Simple Explanation
President Trump decided to keep a rule going that makes it hard for certain people from other countries to come to the U.S. for work, so people already here can have more job opportunities as things get better after the virus problems.
