Proclamation 9993 of March 11, 2020, titled Proclamation - Suspension of Entry as Immigrants and Nonimmigrants of Certain Additional Persons Who Pose a Risk of Transmitting 2019 Novel Coronavirus. "The entry into the United States, as immigrants or nonimmigrants, of all aliens who were physically present within the Schengen Area during the 14-day period preceding their entry or attempted entry into the United States is hereby suspended and limited subject to section 2 of this proclamation... This proclamation is effective at 11:59 p.m. eastern daylight time on March 13, 2020. This proclamation does not apply to persons aboard a flight scheduled to arrive in the United States that departed prior to 11:59 p.m. eastern daylight time on March 13, 2020." Although in his address President Trump reportedly said the ban would last 30 days, the proclamation language itself states that it "shall remain in effect until terminated by the President."
