Italy Citizenship by Descent (Jure Sanguinis) 2026 — The Complete Guide
The basic rule
Italian citizenship passes through blood. If you have an Italian ancestor who was an Italian citizen at the time of their child's birth, you are entitled to Italian citizenship — with no generational limit in theory. An ancestor who emigrated in the 1880s can still pass citizenship to their great-great-grandchildren today.
The 1948 rule
The most important limitation: before January 1, 1948, Italian citizenship passed only through the male line. A woman could not pass Italian citizenship to her children. After 1948, both men and women can pass citizenship equally.
This means: if your qualifying Italian ancestor is a woman who had children before 1948, you cannot claim through the standard consular route. You can, however, bring a court case in Italy under the so-called 1948 rule — Italian courts have consistently ruled that this gender discrimination is unconstitutional. Court cases for 1948 claims typically take 1–3 years.
The naturalisation break
Italian citizenship is broken if your ancestor naturalised as a citizen of another country BEFORE the birth of the next person in your chain. If your Italian great-grandfather became an American citizen in 1905 and your grandfather was born in 1907, the chain is broken and you do not qualify. If he naturalised in 1908 after your grandfather's birth, the chain is preserved.
How to apply
Through the Italian consulate in your country (for standard patrilineal claims before 1948, or any claim after 1948): you compile your documentary evidence — birth certificates, marriage certificates, death certificates and naturalisation records for every person in your chain — and submit an application. Consulates are significantly backlogged — wait times of 3–8 years are common in high-demand consulates (New York, Buenos Aires).
The Italian court route: filing directly with a court in Italy. Much faster (1–2 years) but requires an Italian lawyer and is more expensive (EUR 5,000–15,000 including legal fees).
Why it matters
An Italian passport is an EU passport — the right to live and work in 27 countries. It also provides visa-free access to 188 countries. For Americans, Brazilians, Argentines and Australians with Italian heritage, it removes the need for visas to Europe permanently.
