• Economic and social contributions of undocumented immigrants are significant, with billions contributed in taxes and vital roles played in the workforce.
• No evidence supports claims that sanctuary policies increase crime rates, according to academic research.
• The ongoing conflict between state and federal authorities creates uncertainty and a chilling effect for immigrant communities, impacting access to public services and overall well-being.

California’s Sanctuary State Law: Legal Framework and Protections

Sanctuary State Law (SB 54, 2017)
California’s sanctuary status is rooted in Senate Bill 54, signed into law in 2017. This law:

• Prohibits state and local police from asking about immigration status during routine stops or investigations.
• Prevents local law enforcement from holding undocumented immigrants solely for federal immigration authorities.
• Restricts assistance to federal agencies like ICE (Immigration and Customs Enforcement) in immigration enforcement activities.

These measures are designed to protect undocumented immigrants from being detained or deported simply because of their immigration status. The law also aims to build trust between immigrant communities and local police, encouraging crime reporting and cooperation without fear of immigration consequences.

Local Sanctuary Policies
Many California cities, including Los Angeles and San Francisco, have their own sanctuary policies that go back decades. For example:

• Los Angeles’ Special Order 40 (1979): Prohibits police from stopping people solely to determine their immigration status.
• San Francisco’s Sanctuary Ordinance (1985): Limits city cooperation with federal immigration enforcement.

These local policies reinforce the state’s broader commitment to protecting undocumented immigrants.

Recent Legislative Actions: SB 48 (2025)
In 2025, California passed Senate Bill 48, which:

• Limits ICE presence on school campuses.
• Protects immigrant students and families from immigration enforcement at schools.
• Aims to prevent fear-driven absenteeism and loss of school funding.

This law responds to concerns that federal enforcement on school grounds discourages attendance and disrupts education for children in immigrant families.

Recent Federal Challenges and California’s Response

Federal Pressure and DHS Actions
In May 2025, the U.S. Department of Homeland Security (DHS) publicly named California as a sanctuary jurisdiction. DHS Secretary Kristi Noem criticized the state’s policies, claiming they protect “dangerous criminal illegal aliens” and put law enforcement at risk.

Operation Guardian Angel (2025)
The U.S. Attorney for the Central District of California, Bill Essayli, launched Operation Guardian Angel, a federal program that:

• Targets individuals charged with illegal reentry after deportation.
• Coordinates federal arrests directly from state jails, bypassing local sanctuary protections.
• Aims to “neutralize” California’s sanctuary laws by increasing federal prosecutions.

This program represents a direct challenge to California’s efforts to shield undocumented immigrants from federal enforcement.

Legal and Political Pushback
California officials have strongly opposed these federal actions. State Superintendent Tony Thurmond, for example, has highlighted the negative effects of federal enforcement on schools and immigrant families. Thurmond’s support for SB 48 reflects the state’s determination to resist federal deportation threats and protect vulnerable communities.

Expert Analysis
Academic experts, such as UC Irvine criminologist Charis Kubrin, have found no link between sanctuary policies and increased crime rates. This challenges federal claims that sanctuary jurisdictions are less safe.

Specific Protections and Practical Implications for Undocumented Immigrants

Law Enforcement Interaction
– Police and local law enforcement in California are not allowed to ask about immigration status during routine encounters.
– They cannot detain people solely for immigration violations.
– This reduces the risk of deportation for undocumented immigrants who interact with local police.

Schools and Public Services
– SB 48 restricts ICE access to school campuses.
– This protection helps ensure that children of undocumented immigrants can attend school without fear of immigration enforcement.
– It also helps schools maintain funding, which depends on student attendance.

Tax Contributions and Economic Role
– Undocumented immigrants in California contribute about $8.5 billion each year in taxes.
– They play key roles in industries like agriculture, construction, and service sectors.
– Despite their contributions, they have limited access to many public benefits.

Detention and Deportation Risks
– Federal immigration authorities continue to operate detention centers in California, some run by private companies.
– These facilities have faced criticism for human rights concerns.
– Increased federal funding for ICE and CBP in 2025 suggests more resources for enforcement, raising the risk of detention and deportation for undocumented immigrants.

Chilling Effect
– The threat of federal enforcement creates a “chilling effect,” where immigrant families avoid public services, schools, and hospitals out of fear.
– This can harm community health, education, and overall well-being, even in a sanctuary state like California.

Historical Context and Policy Evolution

California’s approach to sanctuary policies has evolved over several decades:

• 1979: Los Angeles adopts Special Order 40, one of the first local sanctuary policies.
• 1985: San Francisco declares itself a sanctuary city.
• 2017: California passes SB 54, making sanctuary protections statewide.
• 2025: New laws like SB 48 expand protections, especially in education.

Throughout this period, California has often resisted federal efforts to force local cooperation with immigration enforcement. The return of President Trump to office in 2025 has brought renewed federal pressure, including new executive orders and enforcement programs targeting sanctuary jurisdictions.

Comparisons, Trends, and Patterns

Sanctuary Policies vs. Federal Enforcement

Crime Rates and Sanctuary Policies
– Research shows no increase in crime rates in sanctuary jurisdictions.
– Sanctuary policies are linked to higher trust in police and better community cooperation.

Economic Impact
– Undocumented immigrants’ tax contributions have grown steadily, reflecting their ongoing role in California’s economy.
– Despite federal enforcement, the state continues to benefit from immigrant labor and spending.

Evidence-Based Conclusions

• California’s Sanctuary State Law and related policies provide real protections for undocumented immigrants, especially in interactions with local police and schools.
• Federal enforcement efforts have become more aggressive in 2025, but state and local governments continue to resist cooperation.
• Undocumented immigrants remain at risk of detention and deportation, especially if they come into contact with federal authorities or are charged with certain crimes.
• The economic and social contributions of undocumented immigrants are significant, and sanctuary policies help maintain community stability.
• No evidence supports claims that sanctuary policies increase crime, according to academic research.
• The ongoing conflict between state and federal authorities creates uncertainty and fear, affecting access to services and community well-being.

Limitations

• Sanctuary policies do not provide complete protection; federal authorities can still arrest and deport undocumented immigrants.
• Legal challenges to federal executive orders are ongoing, and court decisions could change the enforcement landscape.
• Data on the chilling effect is limited, as fear and avoidance of services are difficult to measure precisely.
• Economic contributions are estimated and may not capture all informal or cash-based work.
