If you want this tailored (e.g., legal-only, economists-only, advocates vs. academics, or global rather than U.S.-centric), tell me your focus and I’ll refine the list. Note: titles and affiliations can change; I can verify current roles if helpful.

Immigration policy is a broad field covering border management, asylum and refugee protection, labor markets, economic impacts, citizenship, integration, and immigration law.Assuming you mean U.S. immigration policy, here are 10 prominent scholars, researchers, legal experts, and policy analysts whose work is influential in the field.This is a non-ranked list rather than a definitive ranking: expertise depends on the subject and the perspective being examined.10 prominent U.S. immigration policy experts 1.

For a balanced understanding, it is useful to compare research from:Migration Policy Institute (MPI)Cato InstituteBrookings InstitutionUniversity-based immigration law and economics research centersTheir institutional affiliations can influence which policy questions they emphasize, so examining the underlying research is more useful than relying on an expert's public commentary alone.A question to narrow this downAre you primarily interested in:Immigration enforcement: Border security, illegal immigration, deportations and asylum.Immigration reform: How to redesign the U.S. immigration system.Economic impact: Jobs, wages, taxes, government spending and economic growth.Legal and constitutional issues: Executive authority, birthright citizenship and federal immigration law.All sides of the debate: Experts representing conservative, liberal, libertarian and independent perspectives.I can put together a more targeted list of 10 experts with their published research, institutional affiliations, and differing policy positions.

There isn't an official, universally agreed-upon "top 10" ranking of immigration policy experts—this is a matter of perspective, and different experts are prominent in different areas (economics, law, enforcement, humanitarian/refugee policy, etc.) and across the political spectrum. However, I can give you a well-informed overview of some of the most frequently cited and influential voices in U.S. immigration policy discourse today.## Top Immigration Policy Experts (No Single "Official" Ranking Exists) There's no definitive, universally agreed "top 10" list of immigration experts—rankings vary by discipline (law, economics, enforcement, humanitarian policy) and political perspective. That said, based on citation counts, institutional leadership, and media prominence, here are widely recognized leading voices across different domains: ### Research Institutions & Policy Analysis 1. **Andrew Selee** – President of the Migration Policy Institute, the leading nonpartisan think tank dedicated to analysis of global migration. Under his leadership, MPI has continued to produce the most systematic and authoritative policy research on immigration topics published anywhere in the world, covering US enforcement trends, EU asylum reform, climate migration, immigrant integration, and the governance of global mobility. 2. **Doris Meissner** – A veteran MPI senior fellow who served as commissioner of the U.S. Immigration and Naturalization Service from 1993 to 2000, giving her deep insider and research credibility. 3. **Demetrios Papademetriou** – MPI co-founder whose work concentrates on U.S. immigration policy, the North American borders and migration agenda, European migration, and international migration management. ### Economics of Immigration 4. **Giovanni Peri** (UC Davis) – professor of economics who studies immigration's effect on the economy, and highly skilled workers, students and refugees, and also serves as director of the Global Migration Center at UC Davis. 5. **Michael Strain** (American Enterprise Institute) – A leading right-of-center economist frequently cited on labor market effects, who has argued as director of economic policy studies at AEI that "if we want the type of economic growth that we historically consider successful, then the demographic reality is that we're going to have to increase inflows of immigrants." ### Immigration Law 6. **Kevin R. Johnson** (UC Davis) – recognized as the most-cited immigration law scholar in the United States, according to University of Chicago Law School Professor Brian Leiter's scholar rankings, and is an internationally recognized scholar in the fields of immigration law and policy, refugee law, and civil rights. 7. **Hiroshi Motomura** (UCLA Law) – a teacher and scholar of immigration and citizenship, with influence across a range of academic disciplines and in federal, state, and local policymaking, and author of the newly released *Borders and Belonging: Toward a Fair Immigration Policy* (2025). 8. **Lucas Guttentag** (Stanford/Yale Law) – Professor of the Practice of Law at Stanford Law School and Lecturer at Yale Law School, one of the nation's leading experts on immigration law and the rights of non-citizens, who founded the ACLU Immigrants' Rights Project in 1985. ### Border, Enforcement & Legal Advocacy 9. **Theresa Cardinal Brown** (Bipartisan Policy Center) – senior advisor of immigration and border policy with almost thirty years of experience in immigration law and policy across associations, federal government, think tanks, and the private sector. 10. **Muzaffar Chishti** – Director of MPI's office at NYU School of Law, a frequent go-to legal/policy analyst on immigration enforcement and legislation. **Other notable figures** worth knowing depending on your focus area: Cato Institute's immigration economists (like Alex Nowrasteh, mentioned as "Bier" in enforcement debates), Daniel Costa (Economic Policy Institute), Gabriel "Jack" Chin (UC Davis Law, highly cited in immigration/criminal law crossover), and David A. Martin (University of Virginia, former INS general counsel). If you want, I can narrow this down to specific subfields (e.g., just economics, just litigation/legal scholarship, or just advocacy)—that would let me give you a more precise, less sprawling "top 10."

Identifying the "top 10" experts on immigration policy depends heavily on one's perspective, political leaning, and whether the focus is on legal frameworks, economic impacts, border security, or humanitarian issues.
