There is no single easiest European country to get citizenship in — the answer depends on what you bring to the table. If you have Italian, Irish, or Hungarian ancestry, citizenship by descent can skip residency entirely. If you’re married to a European citizen, Spain lets you apply after one year of living there together. If you have neither, Germany now offers the shortest general naturalization timeline in Western Europe: five years, or three for well-integrated applicants, with dual citizenship allowed since 2024. The rules shifted significantly in 2024 and 2025, and some old favorites are no longer favorites.
If You Have European Ancestry
Descent is the fastest route because it usually bypasses residency, language exams, and integration tests. The requirement is documentary: an unbroken chain of birth, marriage, and death certificates linking you to your ancestor, typically apostilled and translated.
Italy
Italy was long the most generous descent country, with no strict generational limit. Decree-Law No. 36, issued March 28, 2025, changed that. People born abroad who hold another citizenship are no longer automatically Italian unless a parent was born in Italy, a parent born outside Italy lived there for at least two consecutive years before the child’s birth, or a grandparent was born in Italy.1Consolato Generale d’Italia a Los Angeles. Citizenship by Descent In practice, most new claims are now capped at the grandparent generation.
Two older rules still trip people up. If there is a woman in your line of descent, Italian citizenship only passes to children born after January 1, 1948. And before August 16, 1992, an Italian who voluntarily naturalized elsewhere lost Italian citizenship, breaking the chain for any minor children living with them at the time.1Consolato Generale d’Italia a Los Angeles. Citizenship by Descent Processing runs 24 to 36 months once you file.
Ireland
If a parent of yours was born in Ireland, you are already an Irish citizen. If a grandparent was born in Ireland but neither parent was, you become an Irish citizen by registering on the Foreign Births Register through the Department of Foreign Affairs.2Ireland.ie. Citizenship After registration you can apply for an Irish passport.3Immigration Service Delivery. Applications Based on Irish Descent or Irish Associations There’s a useful downstream effect: once you’re on the Register, your own children born abroad may be eligible through you, but each generation must register before the next is born.
Hungary
Hungarian law follows jus sanguinis without a strict generational cap. If a parent or grandparent was a Hungarian citizen (or was one when you were born), you are likely already Hungarian. More distant ancestry can qualify through simplified naturalization, but you must speak Hungarian. Watch the exceptions: before October 1957, a Hungarian woman who married a non-Hungarian man lost her citizenship, and children born to a Hungarian mother and non-Hungarian father before that date did not automatically get citizenship. Ancestors who emigrated before September 1929 generally did not pass citizenship to descendants.4Embassy of Hungary. About Hungarian Citizenship
Other Ancestry Routes
Poland has no strict generational limit for descent, but the chain breaks if an ancestor naturalized elsewhere or served in a foreign military. Bulgaria allows descent claims up to great-grandparents. Greece is stricter: citizenship passes only from parent to child, with no grandparent pathway.5Greek Ministry of Foreign Affairs.

If You Need to Naturalize
Without ancestry or a European spouse, you’ll go through naturalization after a period of legal residency. Requirements across the EU range from three to ten years and cluster around five.6Epthinktank. Figure 2 – Minimum Period of Residence Required for Naturalisation in EU-28 Every country also adds language proficiency, financial self-sufficiency, a clean criminal record, and often a civics or integration test.
Germany: Five Years, or Three
Germany reformed its nationality law in June 2024, cutting standard naturalization from eight years to five and permitting dual citizenship for the first time. Applicants with outstanding professional achievement or active volunteering, combined with strong German language skills, can qualify after three years.7BMI. New Law on Nationality Takes Effect You must be able to support yourself and your family without public benefits. Before this reform, most applicants had to renounce their existing nationality, which kept many people from applying at all.
France, Belgium, the Netherlands: Five Years
France requires five consecutive years of legal residency. Belgium offers a five-year track that also demands civic integration (completing secondary education or a 400-hour vocational training program, for instance) and at least 468 days of employment within the five-year period; a slower ten-year track loosens the employment requirement but expects broader social participation. The Netherlands sets its residency bar at five years but generally requires you to renounce your prior citizenship, with narrow exceptions.8Government of the Netherlands. Becoming a Dutch Citizen That renunciation rule takes the Netherlands off the list for many Americans.
Sweden and Ireland: Five Years
Sweden requires five years of continuous residence, four for refugees and stateless persons, and two for Nordic citizens.9Migrationsverket. Apply for Swedish Citizenship Sweden is unusual in Europe for not requiring a language test, though processing has run as long as 47 months. Ireland requires one year of continuous residence immediately before applying, plus four more years within the previous eight — five years overall.10Immigration Service Delivery.

Spain’s Shortcut and Portugal’s Reversal
Spain’s general residency requirement is ten years, but it drops to five for refugees and just two years for nationals of Latin American countries, Andorra, the Philippines, Equatorial Guinea, and Portugal.11Gobierno de España. Acquiring Nationality If you hold one of those nationalities, Spain becomes one of the fastest options in Europe.
Portugal used to be a top pick at five years. In late 2025, the Portuguese parliament approved amendments extending the timeline to seven years for nationals of Portuguese-speaking and EU countries and ten years for everyone else, and added a knowledge-of-culture-and-civic-duties requirement on top of the existing language test.12Governo da República Portuguesa. Government Reinforces Requirements on Citizenship Laws and Residence Portugal no longer belongs on a shortlist of easy options.
If You’re Married to a European Citizen
Marriage shortens the naturalization clock almost everywhere, and Spain shortens it the most. A non-EU spouse of a Spanish citizen can apply after just one year of residency, provided the couple lived together in Spain during that year.11Gobierno de España. Acquiring Nationality That is the shortest marriage-based path in Europe.
Ireland cuts its requirement to three years for spouses of Irish citizens, including one continuous year immediately before applying.10Immigration Service Delivery. Become an Irish Citizen by Naturalisation Sweden reduces its requirement to three years for partners of Swedish citizens, with the couple having lived together for the most recent two.9Migrationsverket. Apply for Swedish Citizenship Hungary requires ten years of marriage, or five with a shared child.4Embassy of Hungary. About Hungarian Citizenship
Immigration authorities look hard at whether the relationship is genuine. Expect questions about how you met, daily routines, finances, and living arrangements, and be prepared for separate interviews if officials suspect a marriage of convenience. The non-EU spouse also needs valid residency status before the citizenship clock can start.
Check Whether Dual Citizenship Is Allowed
Before you commit years to a naturalization process, confirm your target country lets you keep your current passport. If it doesn’t, you’ll have to renounce, and for many applicants that ends the conversation.
Germany’s 2024 reform now permits dual citizenship for naturalizing applicants.7BMI. New Law on Nationality Takes Effect France, Ireland, Italy, Sweden, and Belgium also allow it. The Netherlands generally does not, though it makes exceptions for spouses of Dutch citizens and for nationals of countries where renunciation is impossible or unreasonably difficult.8Government of the Netherlands. Becoming a Dutch Citizen Austria, the Baltic states, and several Central European countries maintain various restrictions. Check both your current country and your target country before you start.
Physical Presence Rules That Can Sink an Application
Residency status is not the same as being in the country. Every European country imposes physical presence rules, and applications routinely fail because someone assumed their residence permit kept the clock running while they were abroad.
Germany counts ordinary residence as uninterrupted by trips of under six months. Poland is stricter: during the ten-year residency period, no single absence can exceed six months and total absences cannot exceed ten months. Denmark allows no more than one year of total absence across its nine-year period. Austria caps time abroad at 20% of its ten-year requirement. Ireland limits absences to 70 days in the year immediately before applying, with a possible 30-day extension in exceptional circumstances.10Immigration Service Delivery. Become an Irish Citizen by Naturalisation If you travel heavily for work, countries with more generous absence allowances are more realistic than those with strict day counts.
The Investment Shortcut Is Mostly Gone
“Golden visa” programs once offered a fast lane. That era has largely closed. Malta’s citizenship-by-investment program, the only European program that allowed a direct exchange of money for a passport, was struck down by the European Court of Justice in May 2025 and shut down. Spain ended its golden visa in April 2025. Portugal removed the real estate component of its program and requires business investment instead, while also doubling its naturalization timeline.
Greece still runs a golden visa, but holders face a seven-year residency requirement before they can apply for citizenship, along with language and integration requirements. A golden visa buys residency, not citizenship, and the gap between the two is measured in years of actual presence in the country. Treat any investment visa as an expensive residence permit that puts you on the same naturalization track as everyone else.
