More than 10 million people have been reported illegally entering the United States since President Joe Biden took office in January 2021, the greatest number in history and of any administration.

They total more than the individual populations of 41 states.

The number of people illegally entering the country surged after Biden and Department of Homeland Security Secretary Alejandro Mayorkas halted many preexisting border security policies, advanced sweeping parole and other policies to release the greatest number of illegal foreign nationals into the country, encouraged people from all over the world to use a phone app to enter the U.S., and facilitated U.S. entry application processes in foreign countries, among others.

Official U.S. Customs and Border Protection data includes 3,201,144 apprehensions in fiscal 2023; 2,766,582 in fiscal 2022; 1,956,519 in fiscal 2021; and 471,954 in the nine months Biden was in office in fiscal 2020.
