In 2025, fewer people crossed the U.S.-Mexico border as a result of improved security and more stringent enforcement. The reinstatement of the “Remain in Mexico” policy, which mandates that asylum seekers wait in Mexico while their cases are handled in the United States, was a significant change. Many migrants have reexamined their journeys as a result of this, as well as quicker processing and more returns to their home countries.

Increased border enforcement deters illegal crossings, and authorities continue to implement health-based policies such as Title 42. Long asylum processing times and safety concerns are two reasons given by some migrants for returning home.

Cooperation between the United States and Mexico has also been crucial. Mexico sent troops to its southern border in 2025 in an effort to slow the flow of migrants before they enter the United States. This coordination, according to analysts, sends a clear message to migrants about increased border control and uncertainty.

The new regulations have generated discussion regarding their effects on people, despite their effectiveness in lowering crossings. As migration is increasingly tightly controlled through collaborative efforts, many people in transit now have to deal with disruption and tough decisions.
