This is the highest rate since mid-2019.
In February, US border guards met 100,441 migrants on the border with Mexico.
This was announced by Troy Miller, acting head of the US Customs and Border Protection.
This is the highest monthly rate after a significant spike at the border in mid-2019.
More than 19,000 of these migrants were families, about 9,500 were unaccompanied minors, and the rest were individual adults, Miller said.
Service representatives said that the statistics take into account repeated border crossings.
