🇪🇺 Country Comparison: Pathways to EU Citizenship

This table provides a high-level comparison of the most popular EU countries for US citizens seeking dual nationality. The requirements, costs, and processing times vary drastically based on the specific Pathway chosen (Descent, Naturalization, or Residency-by-Investment).

⚠️ IMPORTANT CAVEATS & WARNINGS

  • Descent/Ancestry (Jure Sanguinis): This path often has the lowest official government fees but the highest ancestry documentation costs (genealogy research, correcting vital records, and legal/consular fees). Processing times are highly dependent on consular backlogs in your US jurisdiction.
  • Naturalization (Residency): This path generally requires a long-term commitment to living in the country and successfully passing a language and civics test. The total cost includes the fees for the application, language courses, and test certifications.
  • Investment (Golden Visa): This path requires a massive upfront capital outlay (the investment itself) but often the shortest physical residency requirement before you can apply for citizenship. The investment amount is not a fee but a required investment that can often be recovered.
