US border arrests saw a surprising decline in March 2024, defying the expected spring increase. This drop is attributed to more stringent immigration enforcement by Mexico, coupled with dynamic shifts in migration patterns impacting the US-Mexico border landscape.
In March 2024, US border arrests unexpectedly declined, countering the usual spring increase in migration. The Border Patrol recorded 137,480 arrests, a slight drop of 2.3% from February and the first decrease for the month of March since 2017. This reduction is largely attributed to more rigorous immigration enforcement efforts by Mexico. In the initial months of the year, Mexico detained 240,000 migrants, markedly more than in 2023, which led to pushing migrants further south within its borders.
Troy Miller, the acting commissioner of U.S. Customs and Border Protection, noted this reduction and stated that while border arrests have decreased, the agency remains alert for any shifts in migration patterns.
Despite this, Tucson, Arizona, still emerged as the busiest sector for border patrols in March, while historically active areas like the Rio Grande Valley in Texas saw decreased activity.
In addition to patrol data, it was reported that over 44,000 individuals were granted entry into the US in March via the CBP One appointment system, not counting those entering through presidential parole. Venezuelans, Haitians, and Mexicans were the primary nationalities making use of this route since January. Furthermore, more than 400,000 people from Cuba, Haiti, Nicaragua, and Venezuela have been permitted to enter through online applications and financial sponsorship.
This complex situation reflects not only Mexico’s increased enforcement but also shifting patterns of migration, both of which are impacting the broader dynamics of immigration at the US-Mexico border.
