On March 18, 2021, the Biden administration extended ongoing travel restrictions along the United States-Canada and United States-Mexico land ports of entry through April 21, 2021. The restrictions, which were previously set to expire on March 21, 2021, prohibit all “non-essential” travel from entering the United States to prevent the spread of COVID-19. These restrictions have been in effect since March 21, 2020.
As outlined in the latest update published in the Federal Register, the notice of restrictions “does not apply to air, freight rail, or sea travel” between the United States and Canada and/or Mexico. [Emphasis added.] However, the border restrictions are still in force for “passenger rail, passenger ferry travel, and pleasure boat travel” between the United States and Canada and/or Mexico. Most importantly, travel for “work” is considered “essential” for the purposes of the restrictions.

Many countries are now gradually bringing their domestic epidemics under control, but the US is still very serious, and there is no difference between Biden and Trump in this respect.
