Italy offers several pathways to citizenship, each with distinct requirements, timelines, and procedures. For Americans with Italian heritage, citizenship by descent (jure sanguinis) is the most common and often the most direct route. This guide covers every pathway in detail, with practical information to help you determine which option applies to your situation and what the process involves.
Citizenship by Descent (Jure Sanguinis)
Italian citizenship by descent is based on the principle of jure sanguinis (right of blood): if your ancestor was an Italian citizen at the time of their child’s birth, and no one in the direct line renounced or lost Italian citizenship before the next generation was born, you may already be an Italian citizen by law. Recognition of this citizenship is not a grant; it is a formal acknowledgment of a right that has existed since birth.
Eligibility Requirements
To qualify, you must demonstrate an unbroken line of Italian citizenship from your Italian-born ancestor to yourself. The key requirements are that your Italian ancestor emigrated from Italy after March 17, 1861 (the date of Italian unification), your ancestor did not naturalize as a citizen of another country before the birth of the next person in the line (if they naturalized after the child’s birth, the line is preserved), no one in the direct line formally renounced Italian citizenship, and for lines passing through a woman, the child must have been born after January 1, 1948 (due to a historical gender restriction in Italian law; children born before this date through a female ancestor require a 1948 case judicial proceeding).
Required Documents
The documentary requirements are substantial. You will need the Italian ancestor’s birth certificate from the Italian comune of origin, vital records (birth, marriage, death, and divorce certificates) for every person in the direct line from the Italian ancestor to you, a Certificate of Non-Existence of Naturalization (CNN) or naturalization certificate for the Italian ancestor (obtained from USCIS), and all U.S. documents must be apostilled by the issuing state’s Secretary of State and translated into Italian by a certified translator.
Document gathering is typically the most time-consuming phase. Vital records must be obtained from U.S. county clerks, state vital records offices, or equivalent authorities. Italian birth certificates are requested from the comune where the ancestor was born. For a detailed walkthrough, see our citizenship by descent guide.
Two Processing Paths
Consular Application (from the U.S.): You apply at the Italian consulate with jurisdiction over your U.S. state of residence. The process involves booking an appointment (wait times vary dramatically by consulate, from months to several years), submitting all documents for review, and waiting for the consulate to verify documents with the relevant Italian comune and complete processing. Total timeline: typically 2 to 5+ years from initial appointment booking to recognition, depending on the consulate’s backlog.
Application in Italy (via comune): You can also apply directly at an Italian comune by establishing legal residency in Italy. This path requires registering at the Anagrafe (civil registry) of an Italian municipality, submitting your citizenship application and documents to the comune, and the comune processing your application within 120 days (per current regulations, though actual processing times may be longer). This route is significantly faster than the consular path for most applicants and is the approach PortaleItaly specializes in. See our applying in Italy guide for the complete process.
1948 Cases: Maternal Line Before 1948
If your line of descent passes through a woman who had a child before January 1, 1948, the standard administrative process does not apply due to a gender-based restriction in Italian law at the time. However, Italian courts have consistently ruled this restriction unconstitutional, and you can obtain citizenship through a judicial proceeding in an Italian civil court (typically the Tribunale di Roma for applicants residing abroad).
The 1948 case process requires essentially the same documents as the standard jure sanguinis application, plus a legal filing handled by an Italian attorney. Court proceedings typically take 1 to 2 years. Success rates are high, as Italian courts have established strong precedent recognizing these claims. For full details, see our 1948 cases guide.
Citizenship by Marriage
Non-Italian spouses of Italian citizens can apply for citizenship by marriage (jure matrimonii) under the following conditions.
If residing in Italy: you can apply after 2 years of legal marriage (reduced to 1 year if there are children born or adopted by the couple).
If residing abroad: you can apply after 3 years of legal marriage (reduced to 18 months if there are children).
The application is submitted through the Ministry of Interior portal (Portale Servizi). Requirements include a valid marriage certificate, B1-level Italian language certification (CELI, CILS, or PLIDA from an accredited institution), a clean criminal record, and proof of continued marriage at the time of the oath. Processing time is officially 24 months from submission but frequently extends to 36 to 48 months in practice. The Prefettura or Italian consulate handles the final stages, including the citizenship oath (giuramento).
Citizenship by Naturalization (Residency)
Non-EU citizens who have legally resided in Italy for a continuous period can apply for naturalization. For U.S. citizens (non-EU), the residency requirement is 10 years of continuous legal residence. For EU citizens, the requirement is 4 years. For stateless persons or refugees, it is 5 years. For those born in Italy (regardless of parents’ nationality), it is 3 years from the age of 18.
Additional requirements include demonstrable income (minimum thresholds apply, approximately EUR 8,263/year for a single applicant with increases for dependents), B1-level Italian language proficiency, a clean criminal record in both Italy and countries of previous residence, and payment of a EUR 250 application fee.
The application is submitted through the Ministry of Interior portal. Processing takes 24 to 48 months. This pathway is less common for Americans, who typically qualify through descent or marriage, but it applies to those without Italian ancestry who have built a long-term life in Italy.
Citizenship by Birth on Italian Soil
Italy does not follow jure soli (citizenship by birthplace) as the United States does. Being born in Italy does not automatically confer Italian citizenship. However, a person born in Italy to non-Italian parents may apply for citizenship between ages 18 and 19 if they have resided legally and continuously in Italy since birth. This one-year application window is strict, and applications must be filed at the comune of residence before the applicant’s 19th birthday.
Citizenship Through Special Circumstances
Adoption
A child adopted by an Italian citizen acquires Italian citizenship automatically if adopted before age 18 through a process recognized by Italian law. For international adoptions, the adoption must be certified by the Commission for International Adoptions (CAI).
Service to the Italian State
Citizenship can be granted by Presidential Decree to individuals who have performed exceptional service to the Italian state. This is rare and discretionary.
Descent from Pre-Unification Italian States
For ancestors who emigrated before March 17, 1861, citizenship by descent is generally not available through the standard process, as Italy did not exist as a unified nation. However, specific cases involving ancestors from territories that became part of Italy may have options depending on the particular historical circumstances. Legal counsel is recommended for these complex situations.
The Citizenship Oath
All pathways (except jure sanguinis by descent, where citizenship is recognized as always having existed) culminate in a citizenship oath (giuramento di fedeltà alla Repubblica). The oath is taken at the comune (if in Italy) or at the Italian consulate (if abroad). It must be taken within 6 months of receiving the notification of citizenship approval. The oath text affirms loyalty to the Italian Republic and commitment to the Constitution. After the oath, citizenship is officially effective.
Dual Citizenship
Both Italy and the United States permit dual citizenship. Acquiring Italian citizenship does not require renouncing U.S. citizenship, and vice versa. As a dual citizen, you hold full rights and obligations in both countries, including the right to live and work in both countries (and throughout the EU with Italian citizenship), dual passport eligibility, voting rights in both countries, and tax filing obligations in both countries (the U.S.-Italy Tax Treaty prevents double taxation on most income).
After Citizenship: Next Steps
Once citizenship is recognized or granted, the key next steps are obtaining an Italian passport (apply at the Questura in Italy or at the consulate abroad), registering with AIRE (mandatory for Italian citizens residing abroad), and if relocating to Italy, registering residency, enrolling in the SSN, and beginning the process of building your life as an Italian citizen.

Frequently Asked Questions
How far back can I go for citizenship by descent?
There is no generational limit. As long as you can document an unbroken line of Italian citizenship from your ancestor (born in Italy after March 17, 1861) to yourself, you are eligible. Many successful applicants trace their lineage through great-grandparents or great-great-grandparents.
What if my ancestor naturalized as a U.S. citizen?
The critical question is when they naturalized relative to the birth of the next person in the line. If the ancestor naturalized after the birth of their child, the child retained Italian citizenship, and the line continues. If the ancestor naturalized before the child’s birth, the line may be broken at that point.
How long does the entire process take?
Timelines vary significantly. Consular applications from the U.S.: 2 to 5+ years. Applications through an Italian comune: typically 3 to 6 months for processing after residency is established. 1948 court cases: 1 to 2 years. Citizenship by marriage: 2 to 4 years. Document gathering itself can take 6 to 18 months before any application is filed.
Do I need to speak Italian?
For citizenship by descent: no. There is no language requirement. For citizenship by marriage or naturalization: yes, B1-level Italian proficiency is required, demonstrated through an approved certification exam.
