In a dramatic shift, the U.S. southern border has seen a significant reduction in migrant encounters, dropping from 189,359 in March 2024 to just 11,017 in March 2025. This drastic change reflects major policy adjustments under the Biden administration’s executive actions in 2024 and continued by President Trump’s administration in 2025.
At a Glance
- The number of migrant encounters at the southern border plummeted to 11,017 in March 2025, marking the lowest monthly total in three years.
- President Trump’s administration has implemented executive orders aimed at securing the border through physical barriers, enhanced technology, and stricter immigration enforcement.
- A recent reconciliation bill includes billions of dollars for state border security initiatives, reflecting a broader federal effort to bolster border control.
Executive Orders and Border Security
President Trump’s executive orders on border security have been swift and decisive. On his inauguration day, January 20, 2025, the administration signed several new policies targeting the southern border. These orders focus on establishing a physical wall, deterring illegal entry, detaining and removing undocumented immigrants, and pursuing criminal charges against those violating immigration laws[4]. The Trump administration’s approach reflects a commitment to addressing what the White House describes as an “invasion” at the border.
Funding for Border Security
The House and Senate have proposed significant funding for border-related initiatives. The House Rules Committee approved an amendment adding $12 billion for states supporting immigration enforcement, while the Senate bill includes $10 billion for a “State Border Security Reinforcement Fund” and $3.5 billion for reimbursement to states for immigration-related costs. These funds are intended to support state-run programs like Texas’s Operation Lone Star, which has already spent over $11 billion on immigration enforcement.
Impact and Reaction
The drastic reduction in migrant encounters suggests these policies are having a tangible effect. Critics argue that while these measures address immediate concerns, they may overlook humanitarian needs and longer-term solutions. The Trump administration’s approach has also prompted debate over the balance between security and compassion in immigration policy.
Future Developments
As the debate over immigration continues, advancements in border security technology are also gaining attention. The upcoming Border Technology Summit in San Diego will focus on biometrics, non-intrusive inspection, and smart walls, highlighting the evolving landscape of border control. This shift towards technology reflects a broader trend towards more sophisticated and integrated border security systems.
