Arrests for illegally crossing the border from Mexico plummeted 33% in July to the lowest level since September 2020, a result of asylum being temporarily suspended.
The Border Patrol made 56,408 arrests last month, down from 83,536 arrests in June, according to U.S. Customs and Border Protection, its parent agency.
Asylum was halted at the border on June 5 because arrests for illegal crossings topped a threshold of 2,500 a day, though a lack of deportation flights prevents authorities from turning away everyone.
U.S. authorities say arrests dropped 55% after the measure took effect, which followed a steep decline earlier this year that was widely attributed to Mexican authorities increasing enforcement within their borders.
More than 38,000 people were admitted at land crossings through an online appointment system called CBP One, bringing the total to more than 765,000 since it was introduced in January 2023.
More than 520,000 people from Cuba, Haiti, Nicaragua, and Venezuela were admitted through July under a separate policy allowing people from those four countries to apply online with a financial sponsor and arrive at an airport. Permits were recently halted amid concerns about fraud by sponsors.
