In 2025, California became the frontline of a federal playbook for more militarized immigration enforcement.
Raids on California streets and lawsuits that followed helped rewrite the ground rules for how agents can operate. What began as before-dawn operations in Golden State farm towns quickly expanded into a broader nationwide strategy: surprise workplace and neighborhood sweeps and roving patrols miles from the border.
CalMatters reporters across California documented how tactics first seen in Kern County, such as warrantless traffic stops and a heavy reliance on appearance-based profiling, spread statewide and then across the country. The U.S. Supreme Court has upheld these methods.
Early in the second Trump administration, the federal government sent Marines to the border, citing a crisis. Those troops have since quietly gone home.
Hundreds of National Guard troops were deployed to Los Angeles following civil unrest about immigration arrests. President Donald Trump threatened to send forces to the Bay Area, then backed off. State officials objected, while federal leaders characterized the moves as necessary. The standoff deepened long-running tensions between California and the White House over the state’s sanctuary policy and federal authority.
All this fell most heavily on families with deep roots in California. CalMatters found deportations increasingly reached people who have decades-long residence, U.S.-citizen children, stable employment, and even those following legal pathways. ICE detained people at green-card interviews and routine check-ins. The changes destabilized school systems, the agricultural economy, and health care.
A federal lawsuit over a deaf asylum seeker’s prolonged detention exposed gaps in medical care and disability accommodations in immigration facilities. Under Trump, asylum seekers with pending claims lost protection from arrest. A new system is emerging where people trying to follow the rules are easier targets than those evading them. Detention centers drew scrutiny as local authorities shied away from conducting health and safety inspections, while advocates reported worsening conditions inside.
A quieter but equally consequential trend has emerged: The immigrant population shrank. Love them or hate them, Trump’s immigration policies were achieving the administration’s goals. Pew Research found the national immigration population shrank by about 1.4 million people in the first half of 2025, the first decline in half a century. Economists warned about slower growth. State leaders weighed long-term impacts on the workforce, schools, and social service systems.
Enforcement grew more data-driven. Drone surveillance expanded in urban areas, and advocates warned about new uses of artificial intelligence to identify deportation targets and analyze asylum and visa applicants’ digital histories.
2026 outlook: California expects further interior enforcement, additional legal battles over sanctuary laws, funding, and renewed attempts to expand detention capacity. School districts and employers are preparing for more mass removals, while lawmakers are considering new privacy protections.
