Maine’s Approach to Sanctuary City Policies and Protections for Undocumented Immigrants in 2025: An Analytical Review

Purpose and Scope

This analysis examines the status of sanctuary city policies in Maine in 2025, with a focus on Portland and other key jurisdictions. It explores the protections and risks faced by undocumented immigrants, the roles of local and federal authorities, and the ongoing legislative and advocacy efforts shaping the state’s approach. The goal is to provide a clear, evidence-based overview for immigrants, advocates, policymakers, and the general public interested in Maine’s immigration landscape.

Methodology

This review draws on official statements, legislative records, advocacy group reports, and public data from local and federal agencies. It synthesizes information from government sources, including the Department of Homeland Security (DHS), the City of Portland, and Maine’s legislative documents. It also incorporates perspectives from immigrant advocacy organizations such as the Immigrant Legal Advocacy Project (ILAP) and the Maine Immigrants’ Rights Coalition (MIRC). The analysis uses a comparative approach to highlight trends, patterns, and the practical effects of policies on undocumented immigrants in Maine.

Key Findings

• Maine is not officially a sanctuary state, and no city, including Portland, has formally declared sanctuary city status.
• Portland and two counties (Cumberland and Hancock) were named as “sanctuary jurisdictions” by DHS in 2025, but this designation was later removed from public posting.
• Local policies in Portland limit police and city staff from asking about immigration status in most situations, offering some protections to undocumented immigrants.
• Most local law enforcement agencies in Maine do not cooperate proactively with ICE, and there is legislative momentum to further restrict such cooperation.
• ICE detentions and arrests have increased in Maine in 2025, creating fear among immigrant communities despite local protections.
• Advocacy groups and pending state legislation aim to expand legal protections and limit local involvement in federal immigration enforcement.

Data Presentation and Policy Landscape

Sanctuary City and State Status in Maine

• No Official Sanctuary State or City Declaration:
  Maine has not declared itself a sanctuary state. No city, including Portland, has formally adopted the label “sanctuary city.” However, Portland’s city ordinance instructs police and city staff not to ask about immigration status unless required by law or court order. This policy is designed to reduce the risk of undocumented immigrants being identified and detained solely because of their status. Despite these measures, Portland has publicly stated it does not consider itself a sanctuary city.

• Federal Designation and Its Implications:
  In May 2025, the DHS under President Trump’s administration published a list naming Portland, Cumberland County, and Hancock County as “sanctuary jurisdictions.” This designation was based on local policies that limit cooperation with federal immigration enforcement, such as not honoring ICE detainers or refusing to enter into 287(g) agreements (which would allow local officers to enforce federal immigration laws). Shortly after, DHS removed the list from public view, stating it was under constant revision. As of early June 2025, Portland had not received formal notification of its status from DHS.

Local Law Enforcement and ICE Cooperation

• Limited Cooperation with ICE:
  Most local law enforcement agencies in Maine do not have 287(g) agreements with ICE. Only one town, Wells, had signed such an agreement, but it has since paused its participation. There is a growing legislative effort to prohibit these agreements statewide, reflecting concerns about racial profiling and the erosion of trust between immigrant communities and law enforcement.

• Legislative Efforts:
  The Maine legislature is considering several bills in 2025 to protect immigrant communities:

  • LD 1259: Would prohibit local law enforcement from voluntarily entering into 287(g) agreements with ICE. The goal is to prevent racial profiling and encourage immigrants to trust local police without fear of deportation.
  • LD 1022: Seeks to increase access to civil legal aid for low-income residents, including immigrants. This would help ensure due process and legal protections, especially as deportation efforts increase.

Visual Data Summary

Comparisons, Trends, and Patterns

Comparison with Other States and Cities

Unlike some states and cities that have openly declared sanctuary status, Maine’s approach is more cautious. While Portland and some counties have policies that limit cooperation with federal immigration enforcement, they stop short of formal sanctuary declarations. This contrasts with cities like San Francisco or New York City, where sanctuary status is a public and legal commitment.

Trends in Federal-State Relations

The Trump administration’s 2025 executive order increased pressure on jurisdictions perceived as sanctuary areas. DHS’s publication of a “sanctuary jurisdiction” list, including Portland and two Maine counties, marked a new level of federal scrutiny. However, the quick removal of the list and lack of formal notification to local officials highlight the fluid and sometimes unclear nature of federal enforcement priorities.

Patterns in Local Enforcement

• Portland’s Policy:
  Portland’s ordinance not to inquire about immigration status in most cases is a practical protection for undocumented immigrants. It reduces the risk of local police triggering ICE involvement. However, this protection is not absolute, as police may still cooperate with ICE when required by law or court order.

• ICE Activity:
  Despite local protections, ICE detentions and arrests have increased in Maine in 2025. Cumberland County Jail reported holding 60-69 ICE detainees at various times, some transferred from other states. Immigrant advocates report that fear of ICE raids and arrests remains high, and there are cases where local police have questioned individuals about their immigration status, leading to arrests and transfers out of state.

Evidence-Based Conclusions

Protections for Undocumented Immigrants

• Practical Protections:
  Portland’s policy of not asking about immigration status in most situations offers real, though limited, protection for undocumented immigrants. It helps reduce the risk of being reported to ICE during routine interactions with city staff or police.

• No Mandatory ICE Cooperation:
  Most Maine law enforcement agencies do not honor ICE detainers unless required by law. This means that, in practice, undocumented immigrants are less likely to be detained by local police solely for immigration violations.

• Legal Aid and Advocacy:
  Organizations like ILAP and MIRC provide crucial legal support and advocacy, helping immigrants understand their rights and access legal representation. These groups also push for policies that protect immigrants from federal overreach.

Risks and Limitations

• Increased ICE Activity:
  Despite local protections, ICE has stepped up enforcement in Maine. The presence of ICE detainees in county jails and reports of increased arrests show that federal enforcement can bypass local protections.

• Uncertainty from Federal Actions:
  The DHS’s shifting list of sanctuary jurisdictions creates uncertainty for local officials and immigrant communities. The lack of clear communication from DHS adds to the confusion and fear among immigrants.

• Legislative Uncertainty:
  While bills like LD 1259 and LD 1022 could strengthen protections, they are still pending. Their passage and implementation are not guaranteed, leaving immigrant communities in a state of uncertainty.

Limitations of This Analysis

• Evolving Policy Landscape:
  Immigration policies and enforcement priorities can change quickly at both the federal and local levels. This analysis reflects the situation as of July 2025, but new developments could alter the landscape.

• Data Gaps:
  Some data, such as the exact number of ICE detentions originating in Maine versus those transferred from other states, is not publicly available. This limits the ability to fully assess the impact of local policies.

• Local Variations:
  While Portland and some counties have clear policies, other jurisdictions in Maine may have different practices. This analysis focuses on the most prominent examples but may not capture all local variations.

Stakeholder Perspectives

• City Officials:
  Portland Mayor Mark Dion has emphasized compliance with the law while supporting policies that limit immigration status inquiries. He has reserved comment on the DHS designation until receiving formal notification.

• Law Enforcement:
  Cumberland County Sheriff Kevin Joyce acknowledges the presence of ICE detainees but often does not know whether they were arrested locally or transferred from other states. This highlights the complexity of local-federal cooperation.

• Federal Authorities:
  DHS Secretary Kristi Noem has strongly opposed sanctuary jurisdictions, accusing them of harboring criminal illegal aliens and threatening public safety. The Trump administration’s approach has been to identify and sanction jurisdictions that do not fully cooperate with federal immigration enforcement.

• Advocacy Groups:
  ILAP and MIRC continue to advocate for increased legal protections and oppose local cooperation with ICE. They highlight the negative impacts of federal enforcement on immigrant communities and public safety.

Practical Guidance for Immigrants and Advocates

• Know Your Rights:
  Undocumented immigrants in Portland and other parts of Maine should be aware that local police and city staff generally do not ask about immigration status unless required by law. However, ICE activity remains a risk, so it is important to know your rights during encounters with law enforcement.

• Seek Legal Support:
  Organizations like ILAP and MIRC offer legal assistance and can help immigrants understand their options and defend against deportation. Accessing these resources can be critical in times of increased enforcement.

• Monitor Legislative Developments:
  The outcome of bills like LD 1259 and LD 1022 could affect the level of protection available to undocumented immigrants. Staying informed about legislative changes is important for both immigrants and advocates.

Conclusion

Maine’s approach to sanctuary city policies in 2025 is marked by caution and complexity. While the state has not declared itself a sanctuary, and no city has formally adopted the label, local policies—especially in Portland—offer some protections to undocumented immigrants by limiting immigration status inquiries and cooperation with ICE. Federal pressure under the Trump administration has targeted Maine jurisdictions, but the situation remains fluid, with the DHS list of sanctuary jurisdictions being withdrawn and legislative efforts pending.

Advocacy groups play a vital role in supporting immigrants and pushing for stronger protections. The practical reality for undocumented immigrants in Maine is shaped by a mix of local policies, federal enforcement, and ongoing legislative debates. As reported by VisaVerge.com, the evolving landscape means that immigrants, advocates, and policymakers must remain vigilant and informed to protect rights and ensure fair treatment for all residents.

Actionable Takeaways

• Undocumented immigrants in Portland benefit from local policies that limit immigration status inquiries, but should remain cautious due to ongoing ICE activity.
• Legal aid organizations are available to help with immigration issues and should be contacted for support.
• Stakeholders should monitor legislative developments, as new laws could change the level of protection for immigrants in Maine.
• For official updates and resources, consult the DHS and City of Portland websites.

By understanding the current landscape and using available resources, immigrants and advocates can better protect themselves and work toward a more inclusive and fair Maine.
