Why Americans Are Applying For European Citizenship By Ancestry Faster Than Any Other Route In 2026

The Italian consulate in New York has appointments booked into 2027.

The Polish consulate in Chicago is running a six-month wait just for an initial document review. The Irish Foreign Births Register is processing applications submitted in late 2024. The German Federal Office of Administration in Cologne has acknowledged a backlog measured in tens of thousands of files.

These are not small numbers. They are the numbers of a route that has overtaken every other path Americans use to acquire European citizenship.

In 2026, citizenship by ancestry, sometimes called citizenship by descent or jure sanguinis, is the fastest-growing category of European citizenship applications from American applicants. It has surpassed the Golden Visa programs, the long-residency naturalizations, and the marriage-based pathways combined. The reasons are partly structural and partly political, and the trend is accelerating rather than slowing.

The structural piece is that several European countries have simultaneously expanded ancestry eligibility, eliminated dual citizenship restrictions, or both. Germany did this in 2024. Italy maintained one of the most generous descent regimes in Europe until April 2025, when it tightened, but a large pool of pre-tightening applicants is still moving through the system. Portugal expanded Sephardic descent eligibility through 2023 before tightening it. Ireland has consistently allowed claims through grandparent eligibility. Poland recognizes citizenship by continuous descent without generational limits.

The political piece is harder to discuss without sounding partisan, but the data is the data. American applications for second citizenships, across all routes, increased measurably after November 2024. The ancestry route absorbed the largest share of that increase, because it is the cheapest, most accessible, and most legally durable option for the applicants who qualify.

This piece is about why that shift happened, what the major ancestry routes look like in practice, and how the comparative math works for an American family deciding whether to pursue ancestry citizenship at all.

What Citizenship By Ancestry Actually Is

The legal principle behind citizenship by ancestry is jure sanguinis, the right of blood. Most European countries grant citizenship at birth based on parental citizenship, not on place of birth. A child born to an Italian citizen is Italian, regardless of where the birth occurs. A child born in Italy to two foreign parents is generally not Italian by birth.

The descent principle, applied across generations, means that an American whose great-grandparent was Italian at the time of the descendant’s birth may have been Italian since their own birth, even if no one in the family realized it. The citizenship is not granted by application. It is recognized by application. The applicant is asking the government to confirm a status they already had.

This distinction matters in three ways.

The applicant is not subject to residency requirements, language tests, or integration criteria. They are not naturalizing. They are documenting an existing legal status.

The applicant generally cannot lose the original American citizenship by exercising the European one. The US permits dual citizenship in essentially all configurations, and the European countries that previously restricted dual citizenship for restoration applicants have largely eliminated those restrictions, with Germany’s 2024 reform being the most prominent example.

The eligibility is heritable. A grandchild who is recognized as an Italian citizen passes that citizenship to their own children automatically, which extends the option to future generations regardless of whether those generations have any connection to the ancestral country.

These three features make ancestry citizenship structurally different from any visa or residency program. It is the only citizenship route that does not require the applicant to demonstrate ties to the country, because the legal premise is that the ties already exist.

Why The Demand Surged

Three trends converged between 2023 and 2026 to produce the current application volume.

The first was a series of legal expansions in major source countries. Germany’s 2024 reform widened eligibility for descendants of Germans who lost citizenship under the discriminatory rules of the early and mid 20th century, primarily affecting descendants of women who married non-Germans before 1953 and descendants of victims of Nazi-era denaturalization. Spain’s 2022 Democratic Memory Law opened citizenship to descendants of Spanish exiles from the Civil War and Franco era. Portugal’s Sephardic Jewish descent program ran from 2015 through 2023 and produced a large number of recognitions before tightening. Italy’s jure sanguinis framework, while subject to a 2025 tightening that introduced generational limits and stricter documentation requirements, processed a large pre-tightening application pool that is still working through the system.

The second was the elimination of dual citizenship barriers. Several European countries that previously required renunciation of prior citizenship for restoration applicants have moved away from that requirement. Germany made this explicit in 2024. Spain has long had a treaty-based exception that effectively allows dual nationality for Latin American citizens, and applies similar reasoning to American descendant cases in practice. Italy and Ireland have never required renunciation. Portugal does not require renunciation. The path to a European passport now does not require giving up the American passport, and that single change removed the largest hesitation many Americans had about pursuing the route.

The third was the political environment. The post-2024 election period in the United States produced a measurable increase in inquiries to immigration attorneys, consulates, and citizenship genealogy services. The pattern is consistent across reporting from immigration law firms, citizenship-focused genealogy services, and consular staff. The applicants are not exclusively from one demographic, but the volume increase is concentrated in applicants who frame the citizenship as insurance against future political uncertainty rather than as a plan to relocate immediately.

The combined effect has been a backlog at consulates that may take three to five years to clear. Italian consulate appointments in major US cities are now scheduled into 2027 and 2028. Polish consulates are running similar timelines. The Irish Foreign Births Register, which is the equivalent process for Irish descent claims, has been processing applications submitted twelve to eighteen months earlier.

What The Major Ancestry Routes Look Like In 2026

The five most accessible European ancestry routes for Americans, ranked roughly by ease of qualification rather than passport strength, are Italian, Irish, Polish, German, and Portuguese.

Italian citizenship by descent has historically been the most generous route in Europe. Until April 2025, there was no generational limit on Italian descent claims. An American whose great-great-grandfather was Italian at the time of his son’s birth could potentially qualify through the unbroken male line. The 2025 tightening introduced a generational limit that restricts claims to direct descendants up to the great-grandparent generation, with documentation requirements that are stricter than the previous regime. Applicants whose qualifying ancestor was the great-great-grandparent or earlier can no longer apply through the standard jure sanguinis process. The tightening also closed certain pre-1948 maternal line cases that had been litigated through the Italian courts. Despite the restrictions, Italian descent remains one of the most common American ancestry citizenship pathways because the underlying immigration history is so widespread.

Irish citizenship by descent is governed by the Foreign Births Register and is among the most straightforward European ancestry routes. An American with at least one Irish-born grandparent is eligible to register as an Irish citizen, regardless of whether the parent through whom the claim flows ever registered. An American with an Irish-born great-grandparent may also qualify if the parent through whom the claim flows registered before the applicant’s birth. The documentation requirements are demanding but well-defined. The Foreign Births Register currently runs a backlog of roughly twelve to eighteen months, but the eligibility criteria are clear and most qualifying applicants succeed without complications.

Polish citizenship by descent is technically not a separate route. Poland recognizes its citizens through unbroken descent from a Polish citizen, and there is no generational limit. The challenge is documentation rather than eligibility. An American whose family emigrated from Poland in the early 20th century is potentially Polish by descent, but the applicant must prove that the ancestor was a Polish citizen, that no one in the chain lost citizenship through the various 20th-century events that affected Polish nationality (including military service in foreign armies before 1951, certain naturalizations as foreign citizens, and the territorial changes of 1939 and 1945), and that the chain of descent is documented. Polish ancestry cases are some of the most complex in Europe, but they also offer one of the longest reachable timelines.

German citizenship by descent opened significantly with the 2024 reform. The qualifying ancestors fall into specific categories, primarily descendants of Germans who lost citizenship through pre-1953 marriage to a non-German or through Nazi-era denaturalization. The route is not a general “German ancestry equals German citizenship” pathway, but for the families with the right qualifying events in their history, it is now one of the more accessible routes in Europe.

Portuguese citizenship by descent is the narrowest of the five. The standard descent route covers children and grandchildren of Portuguese citizens. The Sephardic Jewish descent program, which opened in 2015 and tightened significantly in 2022 and again in 2023, is no longer accepting most new applicants. American descendants of Portuguese emigrants from the late 19th and early 20th centuries may qualify if they can document the chain through grandparents, but the great-grandparent claims that were possible in some interpretations are not currently part of the standard route.

The other European ancestry routes, including Hungarian, Czech, Slovak, Romanian, and Lithuanian, exist but apply to smaller American descendant populations.

How The Comparative Math Works

A useful way to think about which European citizenship to pursue, for Americans who qualify for more than one, is to compare four factors: passport strength, EU membership status, dual citizenship comfort, and processing timeline.

All five major routes deliver an EU passport. The country of citizenship is largely irrelevant to the practical benefit of EU free movement. An Italian passport, an Irish passport, a Polish passport, a German passport, and a Portuguese passport all deliver the same right to live, work, study, and retire in any of the 27 EU member states. The differences in passport strength for visa-free travel outside the EU are small and rarely the deciding factor.

Dual citizenship rules are now broadly aligned. All five countries permit dual citizenship with the United States in their current legal framework. The historical concerns about losing US citizenship by acquiring foreign citizenship were largely resolved by the US Supreme Court’s 1967 decision in Afroyim v. Rusk and subsequent State Department policy, and the historical concerns about the European countries requiring renunciation have been resolved by the legal reforms of the past decade.

Processing timeline is the most variable factor. Irish Foreign Births Register applications currently take twelve to eighteen months. Italian jure sanguinis applications through US consulates currently take three to five years from appointment to recognition, with the appointment itself often scheduled two years out. Polish applications, when documented well, take eighteen to thirty months. German applications under the 2024 reform are running twelve to twenty-four months. Portuguese applications run twelve to twenty-four months. The applicant who needs a passport quickly should choose the fastest available route. The applicant whose family history makes only one route available has no choice.

Documentation difficulty varies significantly. Italian descent cases require extensive vital records from Italian comuni, which respond to requests at variable speeds. Irish descent cases require Irish civil records, which are reasonably accessible but may require Irish-side research. Polish cases are the most documentation-heavy, often requiring archival research in Poland and adjacent countries. German cases under the 2024 reform require evidence of the qualifying event, which can be straightforward in pre-1953 marriage cases and more complex in Nazi-era denaturalization cases. Portuguese cases are relatively well-defined.

The honest comparison for an American with multiple potential ancestry routes is that Irish descent is the easiest when available, Italian descent is the most generous in eligibility despite the 2025 tightening, German descent is the fastest emerging route, and Polish descent has the longest reachable timeline but the highest documentation difficulty.

What The Cost Looks Like

Citizenship by ancestry is among the cheapest second-citizenship routes available anywhere in the world. A typical American applicant, working with a moderately complex documentation chain, spends between 1,500 and 6,000 dollars for the entire process. The cost components fall into a predictable pattern.

Vital records ordering, including birth certificates, marriage certificates, and death certificates from US states and the European country, typically runs 300 to 800 dollars depending on the number of documents and the responsiveness of the relevant offices. Apostille authentication for US documents runs 20 to 50 dollars per document through state Secretary of State offices. Translation costs vary widely by language and document volume, typically running 600 to 2,000 dollars for a complete file.

Consular fees vary by country. Italian jure sanguinis applications carry a fee of around 300 euros per applicant. Irish Foreign Births Register applications cost 278 euros. German declarations are 51 euros. Polish citizenship confirmation is around 60 euros. Portuguese applications are around 175 euros.

Optional professional assistance, including specialized attorneys or citizenship genealogy services, runs 2,000 to 8,000 dollars depending on case complexity. The professional help is not required for straightforward cases but can save significant time for complex cases involving missing documents, archival research, or unclear chains of descent.

The total cost compares favorably to every other second-citizenship route. Investment-based citizenship programs in Europe, including the various Golden Visa permanent residency tracks that may eventually lead to citizenship, require investments of 250,000 to 500,000 euros minimum and run multi-year timelines. Caribbean citizenship-by-investment programs require investments of 100,000 to 250,000 dollars. Long-residency naturalization in most European countries requires five to ten years of legal residence, which carries opportunity costs far higher than any document gathering. Marriage-based naturalization requires actual marriage and meaningful residency.

Ancestry citizenship requires only the documentation, the processing fees, and the patience to wait through the consular backlog.

What Americans Are Actually Doing With Their European Passports

The ancestry citizenship cohort is not, by and large, immediately moving to Europe. The pattern is closer to what immigration attorneys describe as portfolio citizenship. The applicants are securing the citizenship as an option, not as an immediate plan.

The most common reported uses, based on consular data and survey research, fall into a few categories.

Insurance against future political uncertainty. This is the most-cited reason in survey research. The applicants frame the citizenship as a hedge, an exit option, a backup plan. They are not necessarily planning to use it, but they want to have the option available in case of significant changes to the US political or legal environment. This use does not require relocation. The passport sits in a drawer. The benefit is the peace of mind.

Educational access for children. EU citizens generally pay domestic tuition rates at EU universities, which in many countries means free or near-free higher education. An American family securing Italian or Irish citizenship for their children effectively secures a tuition-free pathway to European higher education. The cost differential against US college tuition is significant enough that the citizenship pays for itself for any family that uses it for education.

Retirement optionality. Pre-retirees and recent retirees are using ancestry citizenship to open the option of European retirement without depending on the various retirement visa programs that are subject to changing rules. A US citizen retiring to Spain on a Non-Lucrative Visa is subject to renewal cycles, income requirements, and rule changes. A US-Italian dual citizen retiring to Spain is exercising EU free movement and is not subject to any visa requirements at all.

Career flexibility. Younger applicants frame the citizenship as opening the European job market without work permit complications. An American with EU citizenship can take a job in any of 27 countries without sponsorship, which is meaningful for fields like academia, technology, and the arts where European opportunities are competitive with US ones.

Travel convenience. A secondary but real benefit is the use of the EU passport for travel within Europe and for entry to certain countries where US citizens face visa requirements but EU citizens do not. This is the smallest of the typical use cases but is mentioned consistently.

The applicants who plan to relocate immediately are a minority. The majority are securing the citizenship as a long-term option that may or may not be exercised, and in either case is heritable to their children.

What The Process Actually Feels Like

The applicant who starts a European ancestry citizenship process in 2026 should expect a multi-year project that breaks into several distinct phases.

The eligibility research phase. This is the first three to six months. The applicant identifies the qualifying ancestor, traces the chain of descent, and confirms eligibility against the country’s current rules. This is where most people discover whether they actually qualify, and many would-be applicants stop here because the chain breaks somewhere.

The document gathering phase. This is six to twelve months for most cases. American vital records are ordered from state offices. European vital records are ordered from foreign civil registries. Apostilles are obtained. Translations are completed. The full file is assembled.

The consular submission phase. This is the appointment booking and document review. Italian consulates currently book two to three years out for jure sanguinis appointments in major US cities. Other consulates book six to eighteen months out. The submission itself is usually a single appointment with a complete file.

The processing phase. This is the time between submission and recognition. Italian cases run three to five years from submission. German cases run twelve to twenty-four months. Irish cases run twelve to eighteen months. Polish cases run eighteen to thirty months. Portuguese cases run twelve to twenty-four months.

The passport application phase. Once citizenship is recognized, the applicant applies for a passport at the relevant consulate, usually with a wait of four to eight weeks for issuance.

Total elapsed time for a typical American ancestry citizenship process in 2026 is three to seven years, with Italian cases at the longer end and Irish cases at the shorter end. Applicants starting now should plan accordingly.

What The Trend Means For The Next Decade

The European countries running large ancestry recognition processes are aware that they are not designed for the application volumes they are currently receiving. Italy’s 2025 tightening was partly a response to volume concerns. Other countries may follow.

The likely trajectory is gradual tightening across the major ancestry routes. Generational limits may be added or strengthened. Documentation requirements may become stricter. Processing times may extend further before they shorten. The applicants who start now are working through the most generous version of the rules that is likely to be available.

This is not a prediction that the routes will close. It is an observation that the current regime is unusually generous by historical standards, and that political pressure within the European countries to limit ancestry citizenship is real and ongoing. The Italian debate around the 2025 reform produced significant political conflict. Similar debates are happening in other countries.

The American applicants are aware of this. Part of the surge in 2025 and 2026 is driven by a sense that the window may narrow. Whether or not the window actually narrows further, the applicants are choosing not to wait.

Seven Days Of Initial Setup

This is a starter sequence for an American considering whether ancestry citizenship is available and worth pursuing. The aim is to determine eligibility before committing to the full project.

Day 1. Build a basic family tree. Identify all four grandparents and, if possible, all eight great-grandparents. Note birth countries, immigration dates, and naturalization dates where known.

Day 2. Identify potential qualifying ancestors. Cross-reference the family tree against the major European ancestry routes. Focus on Italian, Irish, Polish, German, and Portuguese ancestors as the most accessible cases.

Day 3. Research the specific country’s eligibility rules. Confirm the current generational limits, documentation requirements, and processing timelines for the candidate country. Government immigration websites and major immigration law firms maintain current summaries.

Day 4. Assess the documentation chain. Identify which vital records will be needed for each generation between the qualifying ancestor and the applicant. Note which records are in US state offices, which are in the foreign country, and which may require archival research.

Day 5. Estimate the timeline. Add up the document gathering time, the consular wait time, the processing time, and the passport issuance time. Be realistic about the total elapsed time before a passport is in hand.

Day 6. Decide on professional assistance. Consult one or two specialized immigration attorneys or citizenship genealogy services for an initial assessment. Most offer free or low-cost consultations and can identify problems in the chain that may not be obvious.

Day 7. Make the go/no-go decision. If the eligibility is confirmed, the documentation chain is complete or nearly complete, and the timeline is acceptable, begin the document gathering phase. If significant gaps exist, decide whether the gaps can be closed or whether the project should be deprioritized.

Why The Trend Is Not Slowing

The ancestry citizenship route is structurally favored by the conditions of 2026 in ways that are unlikely to change quickly.

The cost is low. The documentation is achievable. The legal framework is settled. The dual citizenship comfort is high. The political environment in the United States continues to produce demand. The European countries continue to recognize the eligibility of qualifying applicants, even as they tighten the rules at the margins.

The applicants who would benefit most are the ones whose family history makes the route available and who are willing to commit to the multi-year process. The route is not for everyone, but for the Americans who qualify, it remains the cheapest, most accessible, and most legally durable path to a second citizenship currently available in the world.

The consulates are overwhelmed. The backlogs are growing. The rules are tightening at the margins. None of this is reducing the volume of applications, because the structural reasons for the surge are still in place, and the applicants are calculating that the wait is worth it.

For Americans with qualifying ancestry, the question in 2026 is not whether to pursue the route but how quickly to start the process. The applicants who start now will have their passports before the applicants who start in 2028. The applicants who start in 2028 may be working with a stricter set of rules than the applicants who started in 2026.

The trend is clear. The data is clear. The applicants are voting with their files.
