Inside America's Italian Citizenship Surge

italianamericans.com Editorial Team · Citizenship & Heritage · March 21, 2026

The folder sits on the kitchen table. It's a thick one — rubber-banded, with dividers that have grown soft from handling. Inside: a ship manifest from 1907, a birth certificate from Avellino typed on paper the color of old cream, a marriage record on parchment, certified translations for each document, apostille stamps from three state offices, a notarized affidavit, two sets of instructions from the Italian consulate in New York, and a printed confirmation of a wait-time that stretches eighteen months into the future.

Maria Esposito, a 44-year-old attorney in Chicago, has spent eight months assembling this folder. Her great-great-grandfather Carmine left the Campania region in 1907 and never returned. He became an American citizen in 1921. He raised American children who raised American grandchildren who raised Maria. She has never lived in Italy. Her Italian is limited to the words her grandmother used for food.

"This isn't about leaving," she says. "My grandfather would be confused if he knew I was trying to become Italian. But he'd also understand — because he spent his whole life making sure we knew where we came from."

The Numbers Behind the Surge

Ius sanguinis acquisitions among residents in Italy rose from 7,791 in 2021 to 27,514 in 2024, about 3.5 times the 2021 level.

The official data from Italy's national statistics institute tells the story precisely:

The numbers for residents abroad are even more striking. In 2024, recognitions for people living outside Italy reached 113,221 — and for the first time, the route most people used wasn't the consulate. It was the courtroom.

Courts are no longer the last resort. They have become a primary processing lane.

"In 2024, more people obtained Italian citizenship recognition through a courtroom than through their local consulate. Litigation didn't just grow — it surpassed the traditional administrative route."

The Principle at the Center of It All

To understand why this is happening, you have to understand one foundational concept: ius sanguinis — the right of blood.

Italy's citizenship framework is built on the premise that citizenship passes through the bloodline. If your ancestor was an Italian citizen at the time of their child's birth, and that citizenship was never formally renounced before the next generation was born, citizenship transmitted automatically. There was no generational limit. Under Italy's 1992 Law 91, a fifth-generation American descended from a Sicilian immigrant had, in theory, the same legal claim to Italian citizenship as the immigrant's own child.

This is Italy's foundational contrast with the United States, which defaults to ius soli — citizenship by birthplace. In Italy, ius soli is explicitly described in official government guidance as "residual and supplementary," used only when descent cannot be established. The bedrock is bloodline.

For Italian Americans, this framework opened a door that had been there all along, waiting to be found.

With about 16.3 million U.S. residents reporting Italian ancestry in the 2024 ACS one-year estimates — 4.8% of the U.S. population — the pool of people with at least a theoretical claim is enormous. What changed wasn't the law. What changed was that people started looking.

Two Places Where the Bloodline Gets Interrupted

The theory of ius sanguinis is elegant. The practice is messier. For most Italian Americans, the path through the family tree hits one of two specific obstacles — and the distinction between them determines whether you end up at a consulate or in an Italian courtroom.

The 1948 Rule

Italy's official consular guidance states it plainly: descent through the maternal line is recognized only for those born after January 1, 1948. This is the date Italy's new Constitution entered into force, bringing with it equality commitments that ended the pre-constitutional era in which women's citizenship was subordinate to their husbands'.

Before 1948, under older Italian law, women could lose their Italian citizenship automatically upon marriage to a foreign national. If a female ancestor in your family tree married before 1948 and her citizenship was extinguished by that marriage, administrative recognition is blocked — even though the discrimination that caused the interruption is now understood to have been unconstitutional.

These are called "1948 cases," and they are not a niche category. Millions of Italian Americans have maternal-line connections that cross that date boundary.

The workaround is litigation. A landmark 2009 ruling from Italy's Supreme Court (Corte di Cassazione, Sezioni Unite, decision n. 4466/2009) established that citizenship is a permanent legal status — not a grant that can simply be denied by administrative cutoffs — and that courts can recognize citizenship even where discriminatory pre-constitutional provisions created the interruption. This judicial route remains fully intact and is explicitly unaffected by the 2025 reforms.

The Minor Children Naturalization Trap

The second obstacle is less romantic and more common. It lives in the bureaucratic records of the early 20th century, and most families don't discover it until they're deep into the application process.

Under Italy's 1912 citizenship law (Law 555/1912), when an Italian father voluntarily naturalized as a citizen of another country — say, the United States — and had minor children living with him at the time, those children could be rendered legally "foreign" by the father's act. Citizenship transmission to the next generation was interrupted, not by the children's choice, but by their parent's.

Italy's Interior Ministry issued new guidance in 2024 explicitly tightening how this rule is applied: consulate and comune officials are now required to evaluate not just whether an ancestor naturalized, but when — specifically whether minor children were present and co-resident at the moment of naturalization. The timing determines whether transmission was interrupted.

For the many Italian-American families whose immigrant ancestor became a U.S. citizen in the 1910s or 1920s while raising children, this is the moment the folder on the kitchen table gets thicker.

Online Records and Family Research

Digitized records have made some family-history research easier to begin from home, although access and indexing vary.

DNA testing services democratized the discovery phase. By 2019, Pew Research Center found that 15% of U.S. adults had used a mail-in DNA testing service — and 87% of users cited learning where their family came from as a primary reason. The cited 2019 Pew survey describes Americans’ use of consumer DNA testing and their reasons for trying it. It does not show that a test identifies a surname, ancestral village, or citizenship qualification.

Online databases can help readers locate records from home. The time required depends on the family, the archive, and whether the relevant records have been indexed.

The paradox, as the research community quickly discovered, is that making the discovery easy doesn't make the application easy. Finding out that your family came from Avellino province in 1907 is the beginning, not the end. Converting that discovery into certified documents, apostilles, translations, and a legally sufficient chain of evidence is a different project entirely — one that often requires professional help and substantial time.

The American Consulates: Where the Volume Shows Up

The figures below count citizenship acts processed by U.S. consular offices in 2024. They should not be read as a direct measure of public interest or as a count of all citizenship-by-descent applications.

These 4,747 consular citizenship acts in the U.S. represent only the administrative channel. They do not include the substantial and growing number of Americans who pursue recognition through Italian courts — a route that is harder to count but, as the aggregate data shows, now exceeds the consular track globally.

For context: U.S. nationals accounted for 3,980 of the 113,221 resident-abroad recognitions in 2024 — about 3.5%. The larger share came from Brazil and Argentina, where massive Italian emigration in the late 19th and early 20th centuries created comparably large descent populations. The global surge helps explain why Italy responded with nationwide reforms rather than U.S.-specific changes.

The Cottage Industry That Grew Up Around the Process

When a bureaucratic process becomes complex enough, a service industry fills the space between the applicant and the outcome. Italian citizenship by descent has been generating that industry for years, and it grew dramatically as the surge accelerated.

The core workflow requires assembling what practitioners call a "closed loop" record set: every generation's birth certificate, marriage certificate, and death certificate from the Italian ancestor forward, plus evidence about naturalization timing, plus certified translations, plus apostilles from state and federal offices, plus authentication steps specific to each document's origin. Errors anywhere in the chain — a name discrepancy between a ship manifest and a birth record, a missing apostille, an undetected naturalization date that triggers the minor-children rule — can stop an application cold.

The official costs alone are substantial:

The consular fee doubled on January 1, 2025, under Italy's Budget Law — rising from €300 to €600 per adult. Municipal contributions added another layer. For a family of four pursuing recognition, official fees alone can exceed €2,000 before a single translator has been hired.

This environment created four distinct service models:

1. 1.DIY track: families handle archival research themselves, pay official fees, and hire translators selectively. Risk concentrates in document mismatch and naturalization timing.
2. 2.Hybrid model: genealogy specialist for the hard research layers (naturalization index, Italian comune archives) plus an attorney only if litigation becomes necessary.
3. 3.Full-service facilitation: one-stop portfolio assembly firms that handle everything from ancestor discovery through document submission.
4. 4.Litigation-first: used specifically for 1948 cases and for families where administrative denial is anticipated based on known pre-cutoff maternal lines or naturalization timing.

The sociologist Yossi Harpaz, writing about the broader global trend of "compensatory" second citizenship, describes the appeal clearly: people pursue a second citizenship that offers travel freedom, broader opportunities, and an insurance policy — even when they have no immediate plans to move. Harpaz’s research offers one framework for considering why people pursue a second citizenship. It should not be assumed to explain the motives of every Italian American applicant.

The 2025 Turning Point

What had been a steady surge became something more complicated in 2025.

On March 28, 2025, Italy's government enacted a decree — subsequently confirmed by parliament as Law 74/2025 — that significantly narrowed who can claim Italian citizenship automatically by descent going forward. Applicants born abroad who already hold another nationality are, under the new framework, generally treated as not having acquired Italian citizenship automatically unless they meet specific exceptions: having filed applications (or confirmed consulate appointments) by March 27, 2025, or fitting certain conditions related to parents or grandparents with exclusive Italian citizenship or Italian residency.

In January 2025, Italy's Constitutional Court upheld the core of Law 74/2025, confirming a new generational limit for most new applications while preserving protections for applications already in process before the cutoff.

The 1948 judicial pathway is completely unaffected. Applications filed before March 27, 2025 remain fully protected. But the window for new applications under the old unlimited-generation framework has closed.

An American Story

People may pursue Italian citizenship for family, practical, or personal reasons. The documents gathered during the process can also deepen their understanding of a family’s migration history. That research has value regardless of the legal outcome.

Maria Esposito expects her application to take another year. She has memorized the name of the comune in Avellino where Carmine was born. She looked it up on a map. She found a photograph of the main piazza online — small and sun-bleached, surrounded by the kind of stone buildings that have stood through every upheaval of Italian history.

She is not planning to move there. She is planning to visit.

"The folder is getting thicker," she says. "But so is the story."
