Golden visas and citizenship by investment (CBI) get the attention, and most start in the hundreds of thousands of euros. Latvia is the exception, with a company share-capital route near €50,000, though that option may end within months. The European Union lost its only direct citizenship-by-investment route when Malta’s program ended in 2025, so paid access to Europe now runs almost entirely through residence permits that still cost real money.
There is another set of doors, and none of them asks for an investment. Five routes lead to an EU passport on the strength of a qualifying connection alone: Ancestry, a citizenship your family lost, marriage, lawful residence, or your birthplace.
Calling them free takes a small asterisk. Every route carries administrative costs such as government fees, apostilles, certified translations, and often a lawyer, and the residence-based routes cost years of your life lived in the country. What none of them costs is an entry fee.
The question is not whether you can afford EU citizenship. It is whether you already qualify for it. Here are the five ways, and who actually qualifies for each.
1. Claim It Through Ancestry
If you have a European parent or grandparent, ancestry is the cheapest route to an EU passport. Citizenship by descent, or jus sanguinis (Latin for “right of blood”), transmits nationality down the family line regardless of where you were born.
Ireland is the standout. Anyone with at least one grandparent born on the island of Ireland can claim Irish citizenship by registering on the Foreign Births Register, with no residence requirement and no language test. By some estimates, more than 70 million people worldwide claim Irish descent, and many qualify without knowing it.
Hungary offers one of the broadest programs. Since 2010, foreign nationals of Hungarian descent can naturalize without living in the country, and the government has approved more than a million such applications.
Portugal recognizes both children and grandchildren of Portuguese citizens, and its 2026 nationality overhaul left the child and grandchild descent routes intact, though claiming through a grandparent calls for A2-level Portuguese.
Poland, Bulgaria, and Latvia run descent programs with no fixed generational limit, while Lithuania typically reaches back as far as a great-grandparent. Poland asks for a documented citizenship line, whereas Bulgaria and Latvia rest more on proof of origin than on a continuous chain of citizenship.
Since 2019, children and grandchildren of former Czech or Czechoslovak citizens can claim Czech citizenship by declaration, with no language exam and no residence requirement. Slovakia’s 2022 amendment reaches great-grandchildren of Czechoslovak citizens born on its territory, also without a language test, though applicants generally need to hold a Slovak residence permit as a procedural step.
Italy used to be the most generous of all, recognizing descent with no generational cap. That ended in 2025. A law now limits recognition to those whose Italian parent or grandparent held Italian citizenship exclusively, or whose parent lived in Italy for at least two consecutive years after gaining citizenship and before the applicant was born.
Italy’s Constitutional Court upheld the cap in March 2026, though further challenges are still working through the courts. Anyone who filed before the March 27, 2025 cutoff keeps the old rules, and everyone else must meet the narrower test.
The trade-off across every descent route is documentary. You have to reconstruct a family tree with birth, marriage, and death certificates, often apostilled and translated, and the paperwork can take years to assemble and process. The reward is a passport that costs administrative fees rather than a six-figure investment.
2. Reclaim a Citizenship Your Family Lost
Some Europeans did not emigrate by choice. They were stripped of citizenship and forced out, and several countries now let their descendants reclaim what was taken, at no cost and often with no residence or language requirement.
Germany leads here. Under Article 116(2) of its Basic Law and Section 15 of its Nationality Act, descendants of people who lost or were denied German citizenship on political, racial, or religious grounds between January 1933 and May 1945 can reclaim it. Each descendant holds an individual claim, so grandchildren and great-grandchildren can apply even if their parents never did.
Germany runs a second reparation route with a deadline still ahead. A 2021 law lets people shut out by pre-1975 rules that barred German women from passing on citizenship, along with their descendants, reclaim it by declaration with no residence or language requirement, and the window to file runs until August 19, 2031.
Austria opened a parallel route in September 2020. Section 58c of its citizenship law lets direct descendants of those who fled Nazi persecution before May 15, 1955, acquire Austrian citizenship without giving up their current nationality.
These reparation routes reward proof, not money, but their availability shifts. Spain’s Democratic Memory Law, which let descendants of Civil War and Franco-era exiles reclaim nationality, closed to new applicants on October 22, 2025, with the government confirming no extension. Spain’s separate Sephardic-origin program closed in 2019, and Portugal abolished its own Sephardic route in its 2026 reform.
If a reparation claim runs in your family, the window may already be shut, so confirm the current status before you build a plan around it.
3. Marry an EU Citizen
Marriage to an EU national does not hand you a passport, but it shortens the wait considerably. Most member states cut their naturalization timeline for spouses, and a few cut it sharply.
Spain is the fastest. If you marry a Spanish citizen, you can apply for naturalization after just one year of legal residence in Spain, against ten years for most other applicants. Germany reduces its standard five-year requirement to three years for the spouse of a German citizen, provided the marriage has lasted at least two years. Ireland requires three years of marriage plus three years of reckonable residence on the island.
In most states, marriage compresses the residence requirement rather than removing it. You generally still have to live in the country, and immigration authorities scrutinize marriage-based applications closely to screen out arrangements of convenience.
A few states remove the residence requirement entirely, and Portugal asks the least of them. A spouse or recognized partner of a Portuguese citizen can acquire citizenship after three years together without ever living in Portugal, though the 2026 reform tightened the proof of a genuine connection to the country.
Italy also lets a spouse apply from abroad after three years of marriage, halved with children, but requires B1-level Italian.
4. Earn It by Living There
You do not need ancestry or a spouse. Live in an EU country long enough on an ordinary residence permit, from work to study to family reunification, and you can naturalize on residence alone.
Ireland asks for five years of reckonable residence within the previous nine, with no language test, which makes it one of the more accessible routes in Europe. Germany also sets the bar at five years, reduced from eight in 2024, though it requires B1-level German and a citizenship test. Germany scrapped a three-year fast track for exceptionally integrated residents in October 2025, so five years is now the floor for most applicants.
Spain runs a two-track system. Nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea, Portugal, and people of Sephardic origin can naturalize after just two years of residence, while everyone else waits ten.
Timelines are moving, and not in applicants’ favor. Portugal, long the five-year benchmark, extended its requirement in May 2026 to seven years for EU and Portuguese-speaking nationals and 10 years for everyone else, and it now counts the clock only from the date your residence permit is issued.
Applications filed before the law took effect on May 19, 2026 still run under the old five-year rule. The lesson is to confirm a country’s current rule rather than the one it had last year.
None of this requires an investment, but it requires patience and presence. You fund your own life in the country for the qualifying period, meet physical-presence rules, and in most states pass a language or civics exam. Time is the currency.
5. Inherit It From Where You Were Born
The last route is one you cannot choose, but you may already hold it without realizing. Several EU states grant citizenship based on birth in the country, usually conditioned on a parent’s residence rather than granted automatically.
Germany gives citizenship at birth to children born in the country if one parent has lived there legally for at least five years and holds a permanent right of residence. France applies double jus soli (Latin for “right of soil”): A child born in France to a parent who was also born in France is French automatically, and children born in France to foreign parents can acquire citizenship at 18 if they have lived there long enough. Italy lets a person born in Italy to foreign parents apply between their 18th and 19th birthday if they have resided there continuously since birth.
Spain goes further than most. A child born in Spain to a parent who was also born there is Spanish by origin, and a child born in Spain to foreign parents can naturalize after just one year of legal residence, matching the shortest tier in Spanish law.
Portugal ran a similarly open rule until 2026, when it raised the bar to five years of one parent’s legal residence.
Most of Europe rejects unconditional birthright citizenship, so this route rarely helps an adult who was born elsewhere. Where it matters is for the next generation. If you or your children are born in an EU state, or grew up there, an automatic or option-based claim may already exist, and it costs nothing but the paperwork to document it.
A Rare Route Beyond the Five
Every EU country also keeps the discretion to grant citizenship by merit, used to naturalize people who bring exceptional value in science, sport, culture, or public service, with no investment or residence required. It reaches only a handful of people a year and is rarely something you can apply for directly, so it rewards a track record rather than a plan.
Check Which Door Is Already Open to You
The five free routes to EU citizenship share one feature: They gate access behind a qualifying connection rather than a payment. That reframes the search. Before pricing a golden visa, check whether a passport is already within reach through your grandparents, your family history, your marriage, or the years you have spent living in Europe.
The practical first step costs nothing. Map your family tree two or three generations back, pull the birth certificates, and confirm which country’s law your ancestry fits. Then check that the rule still stands, because Italy, Spain, Portugal, and Germany all rewrote parts of their citizenship law in 2025 and 2026, mostly to tighten it, and legislative status is the fastest-decaying fact in this field.
For those who qualify, the payoff is the passport itself: The right to live, work, and study across 27 countries. Since Malta closed its program, no investment buys that passport directly anymore, and even a golden visa buys only a residence permit and the same years of waiting the routes above describe. What clears the way is eligibility, and those who hold a qualifying connection reach the passport on patience and paperwork instead of capital.
