Italy Citizenship by Descent: New 2025 Rules Explained

Italy has fundamentally altered its approach to granting citizenship through ancestral bloodlines, restricting eligibility primarily to individuals with direct ties to parents or grandparents born on Italian soil. This shift, enacted via emergency decree in March 2025 and recently affirmed by the Constitutional Court, ends the era of unlimited generational transmission under the jus sanguinis principle.

Understanding Jus Sanguinis: Italy’s Bloodline Citizenship Tradition

The cornerstone of Italian nationality law since unification in 1861, jus sanguinis—Latin for “right of blood”—allows citizenship to pass indefinitely through family lines without generational caps, provided no formal renunciation occurred. Historically, this enabled descendants of emigrants from the late 19th or early 20th centuries to claim passports, vote, and reside in Italy freely.

Before 2025, proving an unbroken chain from a great-great-grandparent sufficed, fueling a boom in applications. Consulates worldwide processed thousands yearly, with Americans alone submitting over 20,000 in recent peaks. This system’s generosity stemmed from Italy’s diaspora history, where millions fled poverty, wars, and opportunities abroad, yet retained cultural bonds.

The 2025 Decree: A Turning Point in Citizenship Policy

In response to administrative overload—courts and consulates buried under backlogs—the Italian government issued Decree-Law 36/2025, converted into Law 74/2025. Key changes limit transmission to two generations maximum: applicants must trace to a parent or grandparent born in Italy who held exclusive Italian citizenship at the descendant’s birth.

• Parent or grandparent (“dante causa”) must have been born in Italy.
• They retained sole Italian citizenship until the child’s birth or the child’s majority.
• No naturalization abroad by the ancestor before the relevant transmission point.
• Civil documents (birth, marriage, death certificates) must prove the direct line, legalized and translated.

These rules apply to new applications post-March 27, 2025, exempting those with pre-booked appointments. Existing citizens retain status; pending cases proceed under old criteria if filed timely.

Why the Reform? Balancing Heritage and Practicality

Officials cited surging demands straining resources: Italian consulates faced years-long waits, with some applicants camping overnight for slots. The reform prioritizes “genuine connections” to Italy over distant heritage, arguing indefinite transmission dilutes national identity amid dual loyalties.

Critics, including diaspora groups, decry it as discriminatory, violating constitutional equality. Lower courts challenged it, but on March 12, 2026, the Constitutional Court deemed objections largely unfounded after initial hearings. A full ruling awaits, but the signal upholds the law.

Who Qualifies Under the New Framework?

Eligibility hinges on precise proofs. For parental descent: the Italian parent must not have naturalized before your birth. Grandparental cases require the parent (child of the grandparent) to have transmitted citizenship without interruption.

Special conditions for broader eligibility:

• Born in Italy (even with dual citizenship).
• Born abroad but holding no other citizenship.
• Parent resided in Italy for 2+ consecutive years post-citizenship acquisition, before your birth.

Applicants beyond two generations, like those with great-grandparent ties only, face rejection unless via judicial routes, which remain uncertain post-court affirmation.

Application Process: Steps and Documentation Essentials

Pursuing recognition involves consulates or comune (municipalities) in Italy. Start with genealogy research via sites like FamilySearch or Antenati portals for vital records.

1. Gather birth, marriage, death certificates for the entire line.
2. Obtain non-naturalization certificates from ancestor’s country of residence.
3. Legalize via apostille (Hague Convention) or Italian consulate.
4. Translate to Italian by certified translator.
5. Book consulate appointment (waits vary: 1-3 years in U.S.).
6. Submit in person; fees ~€300.

Judicial applications via Italian courts bypass consulate queues but cost €1,000+ in legal fees and take 1-2 years. Post-reform, success for longer chains is doubtful.

Global Diaspora Impact: Millions Affected

Primarily hitting Italian-Americans (est. 17 million claim ancestry), Brazilians, Argentinians. Pre-reform, 100,000+ annual recognitions; now projected 70-80% drop. Benefits lost: EU passport perks like work freedoms, healthcare in Italy, visa-free travel.

Canada’s contrasting 2025 expansion (Bill C-3) restored multi-generational descent, highlighting policy divergences.

Exceptions, Appeals, and Future Outlook

Grandfathered appointments (pre-11:59 PM Rome time, March 27, 2025) use old rules. Ongoing cases likely grandfathered too. Appeals to Constitutional Court continue, but momentum favors restrictions.

Potential 2026 tweaks via legislation could add residency paths or DNA proofs, but none confirmed. Monitor esteri.it for updates.

Frequently Asked Questions (FAQs)

Can I still claim through a great-grandparent?

No, under new admin practices; limited to parent/grandparent. Judicial challenges risky post-court ruling.

Does this revoke existing citizenships?

No, only affects new applications.

What if my ancestor naturalized after my birth?

Transmission occurred; you may qualify if line meets two-generation cap.

How long for consulate processing?

1-5 years; courts faster but costlier.

Is dual citizenship allowed?

Yes for applicants, but ancestor must have held exclusive Italian at transmission.

Strategic Advice for Prospective Applicants

Act swiftly: book appointments ASAP. Hire specialists for document hunts. Consider residency (via work/study) for naturalization after 10 years (or 3 for descendants). EU Golden Visa alternatives exist for investors.

This reform underscores Italy’s pivot toward tangible links over pure heritage, reshaping a cherished pathway for global Italians.
