The United States’s illegal immigrant population soared to an all-time high of 14 million people in 2023 as millions of people illegally crossed into the country from Mexico during the Biden administration’s border crisis, according to a new report.

The Washington-based Pew Research Center revealed on Thursday that the number of illegal immigrants in the country rose by 3.5 million people by 2023 and continued to go higher during former President Joe Biden’s final year in office.
