To get a European passport, you have to become a citizen of one of the 27 EU member states, and there are three realistic ways to do that: claim citizenship through an ancestor, naturalize after living legally in the country for several years, or marry a citizen. There is no single “EU passport” and no EU-level application. Each country writes its own rules, so the same family history or residence plan can produce a passport in one country and nothing in another. Timelines run from a few months for a strong ancestry claim to a decade for naturalization in Spain or Italy.
Once you hold that passport, the payoff is real. EU citizens can enter, live, and work in any member state without a visa or work permit, a right established by Article 21 of the Treaty on the Functioning of the European Union.1European Commission. Free Movement and Residence The freedom extends to family members, covers Norway, Iceland, Liechtenstein, and Switzerland, and opens access to public healthcare and education on largely the same terms as locals.2Federal Ministry of the Interior.

Citizenship Through an Ancestor
If a parent, grandparent, or in some cases a more distant ancestor was a citizen of an EU country, you may already be entitled to that citizenship without ever living in Europe. Every country draws its own line on how far back the chain can reach and what breaks it.
Ireland
An Irish-born grandparent is the trigger. You register on the Foreign Births Register, produce your grandparent’s original civil birth certificate showing parental details, and once registered you are a full Irish citizen entitled to a passport.4Ireland.ie. Registering a Foreign Birth You do not have to live in Ireland. If your Irish connection is through a great-grandparent rather than a grandparent, you generally do not qualify unless your parent registered on the Foreign Births Register before you were born, which keeps the chain alive.
Italy
Italian descent claims have historically had no generational limit. A great-great-grandparent who emigrated in the 1890s could ground a claim, as long as the chain was unbroken and the ancestor was alive on or after March 17, 1861. Italy enacted Law No. 74/2025 in 2025, adding new restrictions. The route is still open but more constrained. Applications go through Italian consulates abroad, and appointment wait times in cities with large Italian-American populations have historically run into years.
Germany
Germany’s 2024 nationality law reform reshaped this area. From June 27, 2024, people born in Germany to foreign parents no longer have to pick one nationality at adulthood, and Germans can acquire a second citizenship without losing their German one. The naturalization residency requirement dropped from eight years to five.5Federal Foreign Office. Germany’s Nationality Law – Significant Changes The changes are not retroactive. If you lost German citizenship before June 27, 2024, by taking another nationality, you need a separate restoration process.
Citizenship Through Naturalization
Naturalization is the standard route for people without European ancestry. You live legally in the country for a set number of years, then meet language, financial, and character requirements. The residency clock generally starts when you receive your first long-term residence permit, not when you first arrive as a tourist.
Residency thresholds break down roughly as follows:
- Five years in France, Germany, Finland, Sweden, the Netherlands, and Belgium.
- Six to eight years in Denmark (nine years with potential reductions) and Austria (ten, reducible to six in some cases).
- Ten years in Spain (standard track) and Italy.
Some countries shorten the wait for specific groups. Spain drops to two years for nationals of former Spanish colonies, Andorra, the Philippines, Equatorial Guinea, and Portugal, and to one year for spouses of Spanish citizens. France can reduce its five-year requirement for applicants with a French higher-education degree. Refugees often face shorter timelines across the board.
Language and Civics
Nearly every country requires proof of proficiency in the national language, most often at B1 on the Common European Framework of Reference: intermediate conversational ability that lets you handle everyday situations and explain opinions.6Council of Europe. Language Requirements for Adult Migrants in Council of Europe Member States Some countries require B2 for certain applicant categories. Exemptions sometimes exist for older applicants or people with certain disabilities.
Many countries also test knowledge of history, constitution, and political system. Germany’s citizenship test draws from a pool of 300 questions. France evaluates integration through an interview rather than a written test. Officials use these to assess genuine integration, not just to check a box.
Clean Record and Stable Finances
A clean criminal record is close to universal. You will need police clearance certificates from every country where you have lived for a significant period, not only your current one. Financial self-sufficiency requirements vary, but the principle is consistent: applicants should not depend on social welfare. Proof can come from employment contracts, tax returns, pension statements, or bank balances.7Your Europe. FAQs – Registering Presence After the First 3 Months Some countries just want stable income; others set a minimum pegged to local cost of living.
Investment Routes and Golden Visas
The idea of buying EU citizenship outright has effectively ended. In April 2025, the Court of Justice of the European Union ruled in Case C-181/23 that Malta’s citizenship-by-investment scheme violated EU law, holding that granting nationality in exchange for predetermined payments without a genuine connection to the country commercializes EU citizenship and breaches sincere cooperation between member states.8Court of Justice of the European Union. Commission v Malta – Citizenship by Investment The European Commission had already opened infringement proceedings against Malta and Cyprus, stating that “European values are not for sale.”9European Commission. Investor Citizenship Schemes
What remains are golden visas, which grant residency in exchange for investment, usually in real estate or government bonds. Greece and Portugal still run programs, though both have tightened terms. Portugal extended its residency-before-citizenship period from five to ten years, and Spain closed its program entirely. Greece offers five-year residency tied to real estate or startup investment. A golden visa can lead to citizenship through the normal naturalization process, but it is not a shortcut around residency and integration requirements.
Documents and Costs for a US Applicant
The paperwork is heavier than most people expect. Virtually every document has to be an original or certified copy, officially translated into the destination country’s language, and authenticated with an apostille.
Most European countries want an FBI Identity History Summary. The FBI charges $12 for a fingerprint-based check.10Federal Register. FBI Criminal Justice Information Services Division User Fee Schedule That report then needs a federal apostille from the US State Department’s Office of Authentications at $20 per document. Mailed requests run about five weeks; walk-in drop-off in Washington, D.C., takes about seven business days.11Travel.State.Gov. Requesting Authentication Services Watch the clock: many European countries require the FBI report to be less than three or six months old at submission.
You will also need certified copies of your birth certificate, and probably those of your parents or grandparents for a descent claim. State-issued certified copies typically run $10 to $34. Each gets a separate apostille from the issuing state’s Secretary of State, roughly $2 to $25 per document. State-issued documents get state apostilles; federal documents like the FBI report get federal apostilles.
Certified translations of English-language documents into the destination country’s language can be the single biggest expense. Translators charge by the page, and a complex birth certificate or court document can run $30 to $75 per page. Naturalization itself carries a government processing fee that varies by country and changes periodically, so check with the specific immigration authority or consulate before applying.
Timelines and How Applications Are Filed
Applications go to whichever body handles citizenship in the country: a ministry of interior, an immigration office, or a local municipal authority. Some countries take online submissions; others require an in-person consular appointment if you are applying from abroad.
Processing times are wildly inconsistent. France aims to decide within 18 months. Italian consular descent applications have historically taken two to four years, with some running longer. German naturalization decisions typically arrive within a few months to a year. There is almost no way to speed this up from the outside, and incomplete applications get sent back, restarting the clock. Getting every document right the first time is worth the effort.
Many countries end the process with an oath or allegiance ceremony. Germany holds it at the local government office shortly after approval. Others mail the certificate with no ceremony. Once you have the citizenship certificate, you apply for the passport at a consulate or passport office as a separate step with its own processing time.
Can You Keep Your US Passport?
Whether you can hold both depends entirely on the European country. The US itself has no law against dual citizenship, so any restriction comes from the European side.
Around nine EU countries require naturalization applicants to renounce their previous citizenship, including Austria, the Netherlands, Spain, and several Baltic and Balkan states. The rest allow dual citizenship without conditions. Germany’s 2024 reform was a major shift: non-EU citizens naturalizing in Germany no longer have to renounce, and Germans acquiring a non-EU citizenship no longer lose their German one.5Federal Foreign Office. Germany’s Nationality Law – Significant Changes Even where renunciation is formally required, exceptions sometimes exist for refugees, people who would face extreme difficulty renouncing, or nationals of countries that do not permit renunciation.
Before You Commit: Taxes, Clearances, and Conscription
A European passport does not end your US filing obligations. The United States taxes its citizens on worldwide income wherever they live.12Internal Revenue Service. US Citizens and Resident Aliens Abroad The Foreign Earned Income Exclusion can shield up to $132,900 of earned income for tax year 2026, and the Foreign Tax Credit helps against double taxation, but you have to file to claim either.13Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Opening European bank accounts triggers FBAR reporting (FinCEN Form 114) once your foreign accounts exceed $10,000 combined at any point in the year, filed separately from your tax return.14Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) FATCA reporting on Form 8938 kicks in at higher thresholds for foreign financial assets.15Internal Revenue Service. Summary of FATCA Reporting for US Taxpayers The two overlap and are not interchangeable; you may need to file both. Renouncing US citizenship to escape all this triggers an exit tax if you meet the “covered expatriate” thresholds, and the decision is irreversible.16Internal Revenue Service. Expatriation Tax
If you hold or want a US security clearance, foreign citizenship is a serious complication. Federal adjudicative guidelines flag exercising dual citizenship, using a foreign passport, and accepting benefits from a foreign government as security concerns.17eCFR. Guideline C – Foreign Preference Voting in foreign elections, serving in a foreign military, or holding political office abroad can compound the problem. The State Department applies the same principles internally and will generally not assign a dual citizen to the country where they hold second citizenship; if it cannot clear a new hire, the offer is withdrawn.18U.S. Department of State. Dual Citizenship – Security Clearance Implications If you work in defense, intelligence, or diplomacy, talk to a security clearance attorney before you apply.
Several EU countries still have compulsory military or civil service, among them Austria, Cyprus, Denmark, Estonia, Finland, Greece, Latvia, Lithuania, and Sweden. Gaining citizenship in one of these countries can make you subject to conscription depending on your age and the country’s exemption rules for dual nationals or naturalized citizens. For Americans, voluntary foreign military service only threatens US citizenship if you serve with intent to relinquish it, with a narrow exception for service against the United States or as an officer in certain foreign forces.19U.S. Department of State. Loss of US Nationality and Service in the Armed Forces of a Foreign State If service is a live possibility in your target country, confirm the exemption rules for naturalized citizens or older applicants before you file.
