Dual citizenship can offer significant benefits, but misconceptions about eligibility, pathways, and obligations often lead to wasted time, unexpected costs, and legal pitfalls. Below is a concise fact‑check of the most common myths, based on official government sources up to 2026.
1. DNA or “percentage” ancestry does not qualify you
- No country accepts genetic testing as proof of citizenship.
- Eligibility requires civil documentation (birth, marriage, death certificates) that trace an unbroken line to an ancestor who held the nationality.
- Italy: Until May 2025, any ancestor who was an Italian citizen after 1861 could be used, regardless of generation. The 2025 law now limits claims to a parent or grandparent only; applications submitted after March 2025 fall under the new rules.
- Ireland: Always limited to a grandparent.
- Poland: Requires proof of Polish citizenship; records before 1920 are not recognized.
2. Ancestry is not the only route
- Naturalization: Live legally for a set period, integrate, and pass language/civic tests. Typical residency requirements (2026):
- Greece – 7 years
- France – 5 years (language B2 as of Jan 2026)
- Portugal – 5 years (subject to change)
- Citizenship‑by‑investment (still available outside the EU):
- St Kitts & Nevis, Dominica – investment programs
- Turkey – $400,000 property purchase (citizenship in 6–8 months)
3. Residency does not automatically become citizenship
- All countries require a formal application and usually a civics and language test.
- Examples of recent requirements:
- Germany – naturalization test + B1 German.
- France – B2 French + 40‑question civic exam (80 % pass).
- UK – B1 English + “Life in the UK” test.
- US – 2024 denial rate ≈ 1 in 9 despite meeting residency.
4. Golden visas are not passports (EU)
- Golden visas grant residency, not citizenship.
- Portugal (2023) removed the real‑estate option; only funds, research, or job‑creation investments remain.
- Ireland – investor program ended Feb 2023.
- Spain – entire golden‑visa scheme terminated Apr 2025.
- Greece – €250 k–€800 k property investment yields residency; citizenship still requires 7 years residence + B1 language.
- Outside the EU, Turkey and several Caribbean states still offer direct citizenship for investment.
5. Digital‑nomad visas rarely count toward citizenship
- Croatia, Estonia – permits do not count toward permanent residency or citizenship.
- Ireland “Stamp 0” – income‑based visa, generally not reckonable for citizenship.
- Spain, Portugal, Greece – time on a digital‑nomad visa does count toward the residency period (Spain 10 years, Portugal proposed 10 years but not yet passed, Greece 7 years with renewals).
6. You cannot buy EU citizenship in 2026
- European Court of Justice (April 2025) ruled citizenship‑by‑investment schemes incompatible with EU law.
- Malta – direct citizenship program closed July 2025.
- Cyprus – program shut down in 2020 after abuse scandals.
- Bulgaria – fast‑track citizenship scrapped under EU pressure.
- Investment citizenship remains possible in Turkey and Caribbean nations, but these do not confer EU freedom of movement.
7. Marriage is not an automatic shortcut
- Spousal marriage can shorten residency requirements but still demands application, language, and sometimes civic tests.
- Sample requirements:
- Spain – 1 year legal residence if married to a Spanish national.
- Italy – 2 years residence in Italy + 3 years abroad.
- US – 3 years residence (spouse must be citizen for all three years) + civics exam.
- UK – spousal visa → 5 years “indefinite leave to remain” → citizenship (≈ £2,000 fee).
- Fraudulent marriages carry severe penalties (e.g., US up to $250,000 fine and 5 years imprisonment).
8. Property purchase alone does not grant citizenship
- In the EU, buying property only secures a golden‑visa residency; citizenship still requires the full residency period and language integration.
- Turkey is the notable exception: $400,000 property purchase yields citizenship within 6–8 months.
9. Language exams are substantive hurdles
- France – B2 French (near‑native fluency).
- Germany – B1 German; retake fees €100‑150.
- Italy – B1 Italian; only three exam sessions per year, causing potentially long waits after a failure.
10. Official processing times are optimistic
- US (N‑400) – advertised 8‑10 months; actual up to 13 months.
- Germany – processing varies widely by region.
- Italy – legal deadline extended to 3 years; consular appointment wait ≈ 2 years.
- Portugal – applicants often wait 3 + years after submission.
- Planning major life changes should incorporate at least a double of the advertised timeline.
11. Meeting requirements does not guarantee approval
- Common denial grounds: criminal record, tax non‑compliance, failed character assessment, language or integration failures, prolonged absences during the qualifying period.
- Even low‑overall denial rates can be higher in specific locales (e.g., Berlin).
12. Citizenship carries obligations, not just rights
- Taxation: Only the US and Eritrea tax worldwide income regardless of residence. US citizens must file annual returns, FBAR for foreign accounts > $10,000, and face an exit fee plus capital‑gains tax if net worth > $2 million when renouncing.
- Potential future taxes: France’s 2025 proposal to tax worldwide income of expatriates failed by one vote, indicating a possible trend.
- Estate tax: US citizens enjoy a $15 million exemption; non‑citizen non‑residents receive only $60,000, and only 16 countries have treaties to avoid double taxation.
- Pensions: UK state pension is frozen for retirees in countries without bilateral agreements (≈ 450,000 affected).
- Military service:
- Greece – 12 months mandatory for males 19‑45 (including naturalized).
- Cyprus – 6 months (age 18‑26) or 3 months (older); investors exempt.
- Turkey – 6 months for ages 20‑22; older naturalized citizens considered already served.
Practical takeaways
- Verify the exact documentation chain required for ancestry claims; DNA tests are irrelevant.
- Assess naturalization timelines and language requirements before committing to a residency program.
- Distinguish between residency (golden visa) and citizenship; the former does not guarantee the latter.
- Confirm whether a digital‑nomad visa counts toward the residency period in your target country.
- Anticipate long processing times and budget for possible retakes of language exams.
- Conduct a thorough tax and legal review—especially if you hold US citizenship or plan to acquire a nationality with worldwide tax obligations.
- Consult qualified tax advisors and immigration lawyers before making financial or life‑changing decisions.
