Italian citizenship may be acquired by birth, descent, marriage, naturalisation, or in other circumstances provided by Italian law. Eligibility depends on the legal basis for the application and applicants must satisfy the statutory requirements in force at the time of application.
Citizenship provides the full rights and responsibilities of an Italian citizen; different legal pathways apply depending on personal circumstances, and eligibility requirements vary by acquisition method.
Italian citizenship is governed primarily by Law No. 91 of 5 February 1992, together with subsequent legislative amendments and implementing regulations. Citizenship may be acquired through birth, descent (Jure Sanguinis), marriage, naturalisation, adoption, or special provisions established by law.
Italy primarily follows the principle of Jure Sanguinis (citizenship by descent) rather than unrestricted birthright citizenship — children born in Italy do not automatically become Italian citizens solely because of their place of birth, except in limited circumstances established by law. Many individuals with Italian ancestry may be eligible to claim citizenship by descent, generally needing to demonstrate an uninterrupted line of descent from an Italian citizen and supporting civil status documentation. Applications are commonly submitted through the competent Italian Consulate abroad or the relevant Italian municipality if legally residing in Italy.
Foreign spouses of Italian citizens may become eligible to apply for citizenship if they satisfy the statutory conditions, generally depending on the validity of the marriage, the required qualifying period, continued marital relationship, language requirements, and absence of disqualifying criminal or security issues. Marriage to an Italian citizen does not automatically confer citizenship.
Foreign nationals who have legally resided in Italy for the qualifying period established by law may apply for naturalisation, generally needing to demonstrate continuous lawful residence, sufficient income where required, compliance with Italian law, language proficiency where required, and absence of public security concerns. Approval is discretionary and not automatic upon completion of the qualifying residence period.
Italian legislation contains specific provisions relating to adopted children, children of Italian citizens, and minors residing in Italy under qualifying circumstances — the applicable rules depend on the child's legal status and family circumstances.
The qualifying residence period varies according to the legal basis for the application, with different rules for EU citizens, non-EU citizens, spouses of Italian citizens, individuals with Italian ancestry, and refugees or stateless persons. Certain citizenship applications also require applicants to demonstrate knowledge of the Italian language at the level established by law — consult the Ministry of the Interior for current certification requirements.
Typical documentation includes a valid passport, residence permit where applicable, birth certificate, marriage certificate where relevant, criminal record certificates, proof of lawful residence, proof of income where required, language certification where applicable, and additional documents requested by the competent authority. Foreign documents may require certified Italian translation, legalisation, or an Apostille, depending on the issuing country and applicable international agreements.
Italy generally permits dual or multiple citizenship — applicants should also verify whether their existing nationality permits dual citizenship, as other countries' laws may differ. Italian citizenship may be lost only in the circumstances provided by Italian law; loss of another country's citizenship does not automatically affect Italian citizenship.
Can I become Italian simply by living in Italy? No — lawful residence is only one of several requirements under the naturalisation process. Does marrying an Italian citizen automatically make me an Italian citizen? No — marriage provides a possible legal pathway, but applicants must satisfy all statutory conditions. Does Italy allow dual citizenship? Generally yes, but verify the nationality laws of any other country concerned. Can my children become Italian citizens? Possibly, depending on the applicable citizenship provisions and individual circumstances.
