The Trump Administration has upgraded its warning to Americans against all International travel as the virus outbreak spreads. This is an unprecedented move.
“The Department of State advises US citizens to avoid all international travel due to the global impact of COVID-19,” it said in the new advice. “In countries where commercial departure options remain available, US citizens who live in the United States should arrange for immediate return to the United States, unless they are prepared to remain abroad for an indefinite period. US citizens who live abroad should avoid all international travel.”
The upgrade may have little practical effect because it is not mandatory and there are now limited transportation options for international travel. The only way to ban Americans from going abroad would be to invalidate the use of US passports for such travel, a bar that is currently in place only for NKorea.
Stay home and have a healthy day.
