Citizenship by Descent: Where Americans Qualify

For Americans with European ancestry, citizenship by descent can be the most underrated relocation move available. It doesn't grant residency — you're not "moving" to anything yet — but it grants a passport, which means you can move to any EU country without a visa, work without sponsorship, and bypass the entire residency-visa apparatus that takes up most of this site.

About 17% of Americans claim Italian, Irish, or German ancestry. A meaningful fraction of those are eligible for one of those countries' descent-based citizenship programs, often without realizing it. The eligibility requirements aren't complicated; the documentation requirements are.

This guide covers the major descent programs Americans can still use in 2026, what each requires, where the realistic timelines and costs land, and the patterns we'd want you to know before committing to any of them. It is not legal advice; for your specific case, consult an attorney specialized in citizenship work in the relevant country.

What "by descent" actually means

Citizenship by descent (also called jus sanguinis or "right of blood") is when a country grants you citizenship based on your ancestry — typically a parent, grandparent, or great-grandparent who was a citizen — rather than based on where you were born. It's the inverse of jus soli (the US system, where being born on US soil makes you a citizen).

Most countries that allow descent-based citizenship treat it as either:

• Automatic from birth. You were born a citizen because you have a qualifying ancestor; the application is administrative recognition of an already-existing fact. Italy and (with some caveats) Ireland work this way.
• Naturalization in a special category. You apply for citizenship through a streamlined process for descendants of citizens. Germany's Article 116 works this way.

The legal distinction matters because automatic-from-birth citizenship is theoretically retroactive: if you're recognized in 2026, you've been Italian (for example) since the day you were born. This affects tax, military service, and a few other niche topics, but for most applicants the practical experience is the same — you get a passport, you're a citizen.

The qualifying ancestor must usually have maintained their original citizenship until the next-in-line descendant was born. The classic break point: an Italian immigrant who naturalized as a US citizen before their child was born interrupted the descent line; if they naturalized after their child was born, the line continued. This is why naturalization records (or proof of no naturalization) are the single most important documents in any descent case.

Italy: jure sanguinis

Italy has the most generous citizenship-by-descent program of any major EU country and the largest pool of American applicants. About 25 million Americans claim some Italian ancestry; a meaningful fraction of those have a documentable line to a qualifying Italian ancestor.

Eligibility (the basics):

• You must have an unbroken line of Italian citizenship from an Italian ancestor down to you.
• The ancestor must have been alive after March 17, 1861 (Italy's unification — anyone who left Italy before this date was technically not an Italian citizen).
• Each generation in the line must have maintained Italian citizenship at the time the next-generation descendant was born.
• Law 74/2025 (effective May 24, 2025) caps the consular route at 2 generations — only applicants whose Italian parent or grandparent was a citizen at the time of the next-in-line descendant's birth can apply through a consulate. Great-grandparent (and earlier) lines must now use the Italian judicial route. Minor children of qualifying applicants must be declared by May 31, 2026 to be included under the new framework.

The 1948 catch. Italian women could not transmit citizenship to their children before January 1, 1948. If your line passes through a woman who had a child before 1948, the consulate route is closed. Italian courts (not consulates) have ruled this discriminatory and accept "1948 cases" through judicial proceedings — adding 1–3 years and a few thousand euros in attorney fees, but the success rate is high.

Recent changes. Law 74/2025 was enacted and took effect May 24, 2025, tightening jure sanguinis at the consular level to within 2 generations (parent or grandparent only). Applicants whose qualifying Italian ancestor is a great-grandparent or earlier can no longer file at a consulate — the Italian judicial route is required, typically through a Tribunal in Rome with an Italian attorney (1–3 years and several thousand euros in court and legal fees). The law also sets May 31, 2026 as the deadline for declaring minor children of newly recognized citizens to keep them included under the framework.

Process:

• Consulate route: Book an appointment at your Italian consulate (jurisdiction is determined by your US address). Wait times have been 2–5+ years for an initial appointment in many US consular districts (NYC, Boston, Detroit, LA have been particularly slow). Submit documents. Approval typically issued within 6–18 months of the appointment.
• 1948-court route: Required for lines passing through pre-1948 women; voluntary alternative for anyone wanting to avoid the consulate queue. File in an Italian court (typically Rome). Italian attorney required. Timeline 1–3 years.
• In-Italy route: Establish residency in an Italian commune (small towns are common for this purpose), apply at the local comune. Bypasses the consulate queue but requires 3–6+ months of physical presence in Italy. Fast — many applicants approved in 6–12 months.

Documentation:

• Birth, marriage, and death certificates for every step from the Italian ancestor down to you.
• Naturalization records (or proof of no naturalization) from US National Archives.
• Italian birth certificates (estratto di nascita) for the ancestor — obtained from the comune of birth in Italy.
• All US documents must be apostilled by the state of issuance.
• All documents must be translated into Italian by a certified translator.

Cost:

• DIY: $1,500–$3,500 in document acquisition, apostilles, translations.
• With an Italian citizenship service: $5,000–$12,000+.
• 1948-court route adds $3,000–$8,000 in court fees and Italian attorney representation.

Ireland: Foreign Births Register

Ireland's descent program is simpler than Italy's and uniquely well-suited to grandparent-route applicants.

Eligibility:

• You qualify if you have a grandparent who was an Irish citizen at the time of your birth.
• You can also qualify if you have a great-grandparent who was Irish and one of your parents was registered on the Foreign Births Register before your birth. The order-of-operations rule (parent registers, then you can register, then your children can register) is strict.

Process:

• Apply through the Foreign Births Register at the Irish embassy or consulate.
• Submit documents online and by mail.
• Review and approval typically 6–18 months.
• Once registered, apply for Irish passport. Passport issuance takes 4–8 weeks.

Documentation:

• Your birth certificate.
• Your parent's birth certificate.
• Your Irish grandparent's birth certificate (obtained from the Irish General Register Office — gro.ie offers online ordering).
• Marriage certificates for any name changes in the line.
• Proof of Irish grandparent's citizenship at the time of your birth (often the birth certificate suffices; sometimes additional documentation).

Cost:

• Document acquisition and apostilles: $200–$600.
• Embassy application fee: ~€278.
• Irish passport fee: ~€80–€110.
• With an Irish solicitor (rarely needed): $1,500–$3,500.

The key rule for families: if you have a great-grandparent Irish line, you must register before your children are born for them to be eligible to register too. Many Irish-descended Americans hit this catch unexpectedly because they assume they can register their family in any order.

Germany: Article 116 (Restoration of Citizenship)

Article 116(2) of the German Basic Law provides a path to German citizenship for descendants of Germans who had their citizenship revoked between January 30, 1933 and May 8, 1945 — almost always Jews and other persecuted groups who fled Nazi Germany. Their descendants, regardless of generation, can claim restored citizenship.

Eligibility:

• The ancestor had German citizenship.
• They were persecuted on grounds of "race, religion, or political views" between 1933 and 1945.
• They lost German citizenship as a result (typically through Nazi denaturalization, but also through emigration).
• You are a direct descendant.

There is no generational limit for Article 116. A great-great-grandchild of a German Jew who fled in 1938 is eligible. There is no language requirement, no income test, no German residency requirement.

Process:

• Apply at the German embassy or a consulate in the US.
• Submit documentation of the ancestor's German citizenship, persecution, and descent line.
• Review at the Bundesverwaltungsamt (Federal Office of Administration) in Cologne.
• Timeline typically 12–24 months.

Documentation:

• Birth, marriage, and death certificates down the descent line, apostilled.
• Naturalization or emigration records of the persecuted ancestor.
• Evidence of persecution: this is the unique requirement. Family records, German archival records (often accessible through Bad Arolsen Archives), historical research. A historian or genealogist specialized in German records is often helpful.

Cost:

• Application is free (no German government fee).
• Document acquisition and research: $500–$2,500 (Bad Arolsen Archive searches are free; private research adds cost).
• With an attorney: $2,000–$5,000.

Article 116 is the highest-leverage German option. A separate restoration program for descendants of Germans who lost citizenship through marriage to a foreigner pre-1953 also exists, but is narrower.

Portugal: Sephardic Heritage Nationality (closed June 2025)

Portugal's Sephardic Heritage citizenship law, passed in 2015, granted Portuguese citizenship to descendants of Sephardic Jews expelled from Portugal in the 1490s. The program had no language requirement and didn't require residency in Portugal — just documentation of Sephardic ancestry, validated by one of the Portuguese Jewish community organizations.

The program closed to new applications in June 2025. Pending applications continue to process, but no new applications can be filed. Some applicants whose applications were filed before the closure but who hadn't yet completed the documentation may have a window to complete; verify status with a Portuguese citizenship lawyer.

If you have documented Sephardic ancestry and missed the window, citizenship through this route is no longer available. Spain's parallel Sephardic program closed in 2019 — also not available.

The closure means that for most Sephardic-descended Americans, the practical descent routes are now Italy (if there's any Italian ancestry, as many Sephardic communities settled in Italy after expulsion), or general residency-based naturalization via the Portugal D7 (5 years).

Spain: Democratic Memory Law (closed October 22, 2025 for new applications)

Spain's Democratic Memory Law, passed in 2022, granted Spanish citizenship to descendants of Spanish citizens who went into exile during the Franco regime (primarily descendants of those who fled the Spanish Civil War 1936–1939). The eligibility window was specifically for descendants of:

• Spaniards who lost their nationality through exile.
• Spaniards who were forced into exile and whose children/grandchildren were born abroad.
• Spaniards whose maternal-line citizenship transmission was blocked by pre-1978 Spanish law.

The window for new applications closed on October 22, 2025. Pending applications continue to process. The estimated total approved or pending applications under the law is around 500,000 — a meaningful program, but no longer accepting new entries.

If you have a Spanish ancestor who went into exile and didn't apply during the open window, this route is no longer available. The remaining Spanish path is residency-based naturalization after 2 years for descendants of Spanish-speaking countries (very narrow for Americans) or 10 years for everyone else via the Non-Lucrative Visa or Digital Nomad Visa.

Other notable programs

Hungary offers descent-based citizenship for descendants of Hungarian citizens — particularly relevant for descendants of pre-WWI Hungarian-administered territories (parts of modern Slovakia, Romania, Serbia, Ukraine). Hungarian-language requirement applies.

Poland restoration program for descendants of pre-WWII Polish citizens. Generational limit applies; documentation requirements are significant.

Lithuania offers citizenship restoration for descendants of pre-WWII Lithuanian citizens. Most beneficial for descendants of Jews who left Lithuania pre-Holocaust.

Croatia, Serbia, Slovenia have ancestry-based programs of varying generosity. Bosnia and Romania each have specific programs for ancestral citizens.

These programs serve smaller American populations than Italy/Ireland/Germany but can be powerful for specific ancestry profiles. A genealogist specialized in Eastern European records can often surface eligibility that families weren't aware of.

Documentation and apostille reality

The single biggest variable across every descent program is documentation. The pattern is consistent:

1. Apostille every American document at the state of issuance (US State Department for federal documents like naturalization records).
2. Translate every document into the destination country's language by a certified translator. Italian and German consulates use sworn-translator lists; Ireland operates in English (most American documents need no translation).
3. Name consistency across documents. Italian immigrants often had names anglicized; "Giuseppe Vincenzo Russo" on the Italian birth certificate may be "Joseph V. Russo" on US naturalization records. Each name variation needs either matching documentation or an affidavit attesting that the variations refer to the same person.

The single most common documentation problem is finding the original Italian/Irish/German birth certificate for the qualifying ancestor. Records were destroyed in wars; small Italian comuni have variable digitization; Irish records from the Republic vs. Northern Ireland follow different systems. A genealogist specializing in the country's records (often $100–$300/hour or a flat-fee package) is frequently worth their fee to break through documentation barriers.

Practical sequencing for an American with mixed ancestry

If you have documentable ancestry in multiple eligible countries, the practical sequencing is:

1. Start with the simplest path. Ireland's Foreign Births Register is the most straightforward of the major programs — if you have an Irish grandparent or properly-sequenced great-grandparent line, that's the fastest passport.
2. Pursue Italy in parallel. Italy's queue times are long enough that you can run it concurrently with other applications. Both passports give you the same EU rights, so you don't need both — but the longer Italy queue is worth starting early.
3. Germany Article 116 if eligible. No generational limit, no language requirement, no queue beyond standard processing.
4. The closed programs (Portugal Sephardic, Spain Democratic Memory). If applications are pending, monitor; if not yet filed, the window has passed.

For most American applicants without multiple eligibility paths, the right answer is to focus on the single most-applicable program rather than try multiple. The documentation overhead compounds.

The endgame: an EU passport

Any of these descent programs ends with the same outcome: an EU passport with full European citizenship rights. You can live and work in any of the 27 EU member states without a visa. You can move freely across borders. Your children inherit citizenship. You can access EU healthcare systems as a member state national.

For Americans whose alternative was a multi-year residency-visa-then-naturalization process, a descent-based passport saves a meaningful fraction of a decade. The documentation work is non-trivial, but it's a one-time project rather than an ongoing residency obligation. For applicants with documented eligibility, it's usually the most leveraged move available.

Once you have the EU passport, you can choose any EU country to actually live in — and the country-by-country residency-visa decision becomes a lifestyle decision rather than a legal one.
