How Americans Can Get an EU Passport
Key findings
- For Americans, the actual citizenship routes are family history and ordinary naturalization after genuinely living in an EU country; investment residence can be a specialized bridge into the latter.
- Descent is usually the cheapest and least disruptive pathway if your family tree fits.
- Portugal and Greece still offer investment residence, but neither route buys citizenship. Malta's former direct investor-citizenship program has been discontinued.
An EU passport lets you live, work, study, and retire in any of the 27 member states. For Americans, the realistic routes are to qualify through family history or to earn citizenship after genuinely living in an EU country. This report covers those two acquisition routes first, then investment residence as a possible bridge into ordinary naturalization. Ancestry is by far the cheapest route if your family tree fits.

Pathway 1: By descent or family history — the cheapest, if you qualify
If a parent, grandparent, or (in some countries) earlier ancestor was a citizen, you may be entitled to citizenship with no investment and no relocation. The work is documenting the lineage, not paying for it. Citizeo currently models at least one parent-, ancestor-, diaspora-, or historical-restoration pathway for every EU member state, but not every route is automatic citizenship by descent. Some require a declaration, registration, language ability, residence, or discretionary approval.
| Country | Modeled pathways | Typical scope |
|---|---|---|
| Austria | Citizenship by descent · Nazi-persecution family restoration | An Austrian parent, or a direct descendant of a person who fits the precise Section 58c persecution and Austrian-connection rules. |
| Belgium | Citizenship by descent | A Belgian parent. Born-abroad cases can depend on the parent's birthplace, a declaration before age 5, and retention rules. |
| Bulgaria | Citizenship by descent · Bulgarian origin | A Bulgarian parent or intact citizenship chain; the origin route can reach a documented parent, grandparent, or great-grandparent. |
| Croatia | Citizenship by origin · Emigrant and descendant route | A Croatian parent, or descendants of a qualifying emigrant. The diaspora route has important exclusions even though it has no stated generation cap. |
| Cyprus | Citizenship by descent | A Cypriot parent and certain older Cypriot-origin categories, using the form that matches the birth and family history. |
| Czechia | Descent confirmation · Child or grandchild declaration · Certain former Czechoslovak families | An intact parent-child citizenship chain, a qualifying Czech or Czechoslovak parent or grandparent, or a narrow unresolved former-Czechoslovak status. |
| Denmark | Citizenship by descent | A Danish parent. An older ancestor matters only through an intact chain, and the age-22 retention rule can matter abroad. |
| Estonia | Citizenship by descent | An Estonian parent or an intact chain to a pre-occupation citizen under Estonia's continuity rules. |
| Finland | Citizenship by descent | A Finnish parent. Older ancestry works only through an intact chain, and dual citizens abroad may face an age-22 retention rule. |
| France | Citizenship by descent | A French parent or intact older chain. Long-abroad families can face France's 50-year proof restriction. |
| Germany | Citizenship by descent · Historic gender inequality · Article 116 restoration · Section 15 restoration | An intact German citizenship chain, a qualifying post-1949 gender-discrimination case, or descent from a person affected by Nazi persecution under one of two restoration routes. |
| Greece | Citizenship by descent | A Greek parent. Older ancestry may require citizenship determinations and civil registration for each earlier generation first. |
| Hungary | Descent confirmation · Simplified naturalization · Pre-Trianon ancestry | An intact Hungarian chain, or documented Hungarian citizenship or origin plus independently usable Hungarian for simplified naturalization. |
| Ireland | Irish-born parent · Grandparent Foreign Births Register · Irish parent born abroad · Parent in Irish public service abroad | An Irish-born parent, a grandparent born on the island, a parent who was already Irish before the applicant's birth, or a narrow public-service exception. |
| Italy | Citizenship by descent | Under the current rules, usually a qualifying exclusively Italian parent or grandparent, or an Italian parent with the required prior residence in Italy; protected pre-reform filings can differ. |
| Latvia | Exile-line restoration · Ethnic Latvian or Liv route | A qualifying descendant of a pre-occupation citizen forced into exile, or documented Latvian or Liv origin under the separate historical rule. |
| Lithuania | Citizenship restoration · Ethnic Lithuanian origin | A former pre-15 June 1940 citizen or that person's child, grandchild, or great-grandchild; or a parent or grandparent who is or was ethnically Lithuanian. Dual-citizenship treatment differs by route. |
| Luxembourg | Citizenship by parent · Parent or grandparent option | A Luxembourgish parent, or a Luxembourgish parent, adoptive parent, or grandparent where nationality did not automatically pass. |
| Malta | Citizenship by descent | A direct-line descendant of a Malta-born ancestor whose parent was also born in Malta, with no stated generation cap. |
| Netherlands | Citizenship by descent · Option procedure | An intact Dutch parent-child chain, or a qualifying option category such as the route repairing certain pre-1985 maternal lines. Dutch automatic-loss rules are central. |
| Poland | Citizenship confirmation · Repatriation | An intact Polish citizenship chain, or a narrow Polish-origin repatriation route for applicants with the required former-USSR residence history who will settle in Poland. |
| Portugal | Citizenship by descent · Resident great-grandchild route | A Portuguese parent or grandparent; a great-grandparent can support a separate route after at least 5 years of legal residence in Portugal. |
| Romania | Citizenship by descent or restoration | An intact Romanian chain or a former Romanian citizen's descendant within the restoration degree limits, including some families from former Romanian territories. |
| Slovakia | Descent confirmation · Descendant grant · Slovak Living Abroad route | A Slovak parent; a parent, grandparent, or great-grandparent who was a Czechoslovak citizen born in present-day Slovakia; or a certificate holder who meets the separate residence or contribution branch. |
| Slovenia | Citizenship by descent · Ethnic Slovene route | A Slovenian parent, subject to registration deadlines abroad, or a parent or grandparent plus the sustained active ties required by the discretionary ancestry route. |
| Spain | Nationality by origin · Nationality by option | A Spanish parent and certain protected birth or adoption cases, or one of the limited parental-authority, parentage, or adult-adoption option categories. |
| Sweden | Citizenship by descent | A Swedish parent. Older ancestry works only through an intact chain, and the age-22 retention rule can matter abroad. |
Important current change: Italy tightened its famous jure sanguinis rule in 2025. For many new applicants born abroad who also hold another citizenship, the key exceptions now concern a qualifying parent or grandparent who held exclusively Italian citizenship, or an Italian parent with 2 continuous years of residence in Italy before the applicant's birth or adoption. Great-grandparent cases are generally closed unless a transition rule protects the filing. Constitutional Court judgment 63/2026 left Article 3-bis in force in the challenge it decided. See the dedicated Italy citizenship by descent after 2025 changes report before counting on an Italian claim.
Several rows include declaration, option, simplified-naturalization, diaspora, repatriation, or restoration pathways because family history determines whether they can apply. Those routes grant or restore citizenship; they are not the same as confirming citizenship that passed automatically at birth. Birth, adoption, marriage, and former-citizen provisions can create still other nationality routes with their own relationship, timing, residence, and documentation rules.
Pathway 2: By naturalization
Move to an EU country on a work, retirement, or digital nomad visa, live there long enough, and naturalize. The headline residence period is only one part of the comparison: the qualifying residence status, physical presence, language, income or self-support, conduct, and integration requirements can matter just as much.
Citizeo currently models ordinary or residence-based citizenship pathways for the 15 EU countries below. The table uses the main route for each country and links separate reduced or alternative residence routes where Citizeo models them. Hungary's simplified naturalization is ancestry-based rather than a general residence route, so it appears in the descent section above.
| Country | General residence timeline | Important planning points |
|---|---|---|
| Austria | Austrian naturalization generally requires 10 years of continuous legal residence, including at least 5 years settled in Austria. Defined 6-year routes and longer 15- or 30-year routes cover particular circumstances. | German and civic knowledge, stable resources, integrity, lawful status, and security requirements apply. Austria also generally requires release from the applicant's previous citizenship unless an official exception applies. |
| Belgium | The principal nationality declarations use 5 years or 10 years of legal residence. | The 5-year route normally requires language, social integration, and economic participation. The 10-year route uses language and participation in the life of the applicant's community. |
| Czechia | Czech naturalization generally requires permanent residence for 5 years, 3 years for an EU citizen, or permanent residence plus prior lawful stay totaling at least 10 years. | Actual presence, Czech language and civic knowledge, clean records, compliance, income, and integration matter. Approval is discretionary. |
| Finland | Citizenship after residence generally requires 8 years, with a common 5-year route for applicants who meet the language requirement and shorter periods for certain defined groups. | Applicants also need accepted identity and language evidence, sufficient resources, paid public obligations, and a qualifying record. A civic-knowledge requirement takes effect for most adult applicants on March 1, 2027. |
| France | French naturalization usually starts after about 5 years of residence, with defined shorter exceptions. | France must normally be the applicant's real center of life. B2 French, the nationality civic exam, integration, tax and work records, and good character are important; approval is discretionary. |
| Germany | German naturalization generally requires more than 5 years of lawful residence. | The applicant needs a status that can support citizenship, self-support, B1 German, civic knowledge, good character, and the required constitutional commitments. Germany generally permits dual citizenship. |
| Ireland | Irish naturalization usually requires 5 years of reckonable residence; a 3-year residence route can apply to spouses and civil partners of Irish citizens. | Good character, the residence calculation, future residence or connection to Ireland, and discretionary ministerial approval matter. Proposed self-sufficiency changes are not yet the current application rule. |
| Italy | Naturalization after residence is usually a 10-year plan for many non-EU citizens. | Shorter periods apply to some EU citizens, refugees or stateless people, adult adoptees, and people with specific Italian family or birth ties. |
| Luxembourg | Luxembourg naturalization generally requires 5 years of legal residence, with the final year uninterrupted. | Luxembourgish language, civic-course or test requirements, and good character also apply. |
| Netherlands | Dutch naturalization usually requires 5 consecutive years of qualifying lawful residence, with defined exceptions. | The residence purpose, civic integration, public-order record, ceremony, and the general requirement to renounce another citizenship all need review. |
| Poland | Citizenship by recognition has several categories ranging from 1 to 10 years, tied to permanent residence, EU long-term residence, or another listed status and basis. | The exact category controls the timeline. Polish-language proof is generally required, while some categories also require stable income and housing. |
| Portugal | Ordinary naturalization is now generally 7 years for EU and CPLP citizens and 10 years for most others. | Transition treatment may apply to applications already pending before May 19, 2026. |
| Romania | Romanian naturalization generally requires 8 years, or 5 years for a person married to and living with a Romanian citizen; narrower reductions may apply. | Long-term or permanent residence is required at filing, along with lawful means, Romanian language and civic knowledge, good conduct, and loyalty requirements. |
| Spain | Ordinary naturalization is usually a 10-year route for Americans. | A reduced Article 22 period or another Spanish nationality route may apply to particular applicants; most Americans using ordinary naturalization also face a renunciation declaration. |
| Sweden | Citizenship after residence generally requires 8 years, with shorter periods for certain Nordic citizens, former citizens, partners, refugees, stateless people, and younger applicants. | A qualifying residence status, identity, Swedish-language and civic knowledge, self-support, and conduct requirements also apply. The dedicated citizenship language test is still being developed, so applicants should check which proof routes are accepted when they apply. |
Pathway 3: Investment residence as a bridge to naturalization
Direct EU citizenship by investment is no longer an available public program. Malta discontinued its former Exceptional Services by Direct Investment framework after the Court of Justice held that the transactional investor-citizenship scheme violated EU law. Malta's current citizenship-by-merit process is expressly not a program, continuation, or alternative to the former investment framework; it is discretionary and reserved for exceptional service, contribution, or interest. See Aġenzija Komunità Malta's discontinuation notice and citizenship-by-merit clarification.
Two investment-residence routes in Citizeo's catalog remain open, but their citizenship value is easy to overstate:
| Country | Current investment option | Relationship to citizenship |
|---|---|---|
| Greece | The Golden Visa remains an active residence-permit framework for qualifying real-estate, financial, and startup investments. | Greece lists an investor residence permit among the titles that can support a naturalization application, but the applicant must actually complete the required period of continuous legal residence and prove language, economic, and social integration. Merely holding and renewing an investment permit while living elsewhere is not a passport route. See the Greek Golden Visa page and Greek Citizenship Code. |
| Portugal | The Golden Visa (ARI) remains available through qualifying non-real-estate funds, research, cultural support, business capitalization, or job creation. Ordinary home purchases no longer qualify. | AIMA says an ARI holder may seek naturalization only after meeting the separate Nationality Law requirements. For most Americans, ordinary Portuguese naturalization is now generally a 10-year route. The Golden Visa's low minimum-stay rules should not be confused with automatic citizenship eligibility. See AIMA's current ARI guidance. |
What this means for Americans
- You will likely able to keep your US citizenship. The US permits dual nationality, and most descent or birth recognition cases do not require giving up a US passport. The destination country's rules still matter: Spain generally asks non-exempt naturalization applicants to make a renunciation declaration at the oath.
- Check descent first. It's free and can hand you a passport that would otherwise cost six figures or a decade of residence.
- An EU passport is one passport for 27 countries — uniquely valuable leverage for relatively little cost if your ancestry qualifies.
