Italian Citizenship by Marriage: Complete Guide

Introduction

Italian citizenship by marriage is one of the main legal paths through which a foreign spouse of an Italian citizen can apply to become an Italian citizen. It is not automatic after the wedding. It is a formal naturalization procedure based on Article 5 of Law no. 91/1992, with specific eligibility rules, document requirements, an online application, ministerial review, and a final oath. The same framework also applies, with the necessary legal adjustments, to civil unions transcribed in Italy. If you are still planning the wedding itself, read our complete guide to marriage in Italy.

Legal framework

The main legal framework is based on Law no. 91/1992, especially Articles 5 to 8, together with the implementing regulations in Presidential Decree no. 572/1993 and Presidential Decree no. 362/1994. Official guidance also reflects the major legislative changes introduced in recent years, including the B1 Italian language requirement, the €250 ministry contribution, and the current procedural term of 24 months, extendable up to 36 months, for applications governed by the post-2020 regime. The old 48-month term should not be presented as the current standard.

Who can apply for Italian citizenship by marriage?

You can apply only if the marriage or civil union is legally valid and still in force. If the marriage took place abroad, it must first be transcribed in the civil status records of an Italian Comune. Marriage alone is not enough if the foreign marriage has never been properly registered in Italy. If you live abroad, the application is handled through the competent Italian consulate for your place of residence. Official consular guidance also states that, in foreign-residence cases, the Italian spouse is generally expected to be registered with AIRE in the competent consular district and to live at the same address as the applicant, unless there is documented justification for a different arrangement.

What are the main requirements?

To apply, the applicant must meet the following conditions:

• Valid marriage or civil union: the relationship must be legally valid and still in force at the relevant stages of the procedure.
• Required waiting period:
  • if living in Italy, you can apply after 2 years of legal residence following the marriage or civil union;
  • if living abroad, you can apply after 3 years from the marriage or civil union;
  • these periods are reduced by half if the couple has children born or adopted together;
  • if the Italian spouse became Italian after the marriage, the waiting period runs from the spouse’s date of naturalization, not from the wedding date.
• No disqualifying criminal or security issues: serious criminal convictions and national-security grounds can block the application.
• Italian language requirement: in most cases, the applicant must prove Italian language knowledge at B1 CEFR level.

Do you always need a B1 Italian language certificate?

In most cases, yes. However, official guidance also recognizes specific exemptions. The clearest established exemptions include applicants who have already fulfilled the integration agreement requirements under Article 4-bis of the Immigration Consolidated Act and applicants who hold an Italian EU long-term residence permit under Article 9 of that same framework. So the rule is not “B1 always, no exceptions.” The correct rule is “B1 generally required, unless you fall under a recognized exemption.”

What documents do you need?

The exact list can vary depending on whether you apply in Italy or abroad and on the authority handling the file, but the core documents usually include:

• a valid identity document or passport;
• the applicant’s birth certificate, properly legalized or apostilled where required and translated into Italian when necessary;
• criminal record certificates from the relevant countries, with the required legalization or apostille and Italian translation where needed;
• the Italian marriage record, or other marriage documentation required by the competent authority;
• proof of payment of the €250 ministry contribution;
• the B1 Italian language certificate, unless an exemption applies;
• residence-related documents where relevant, especially if the applicant is filing from Italy.

One point matters a lot in practice: after the decree is issued, consular authorities may require updated post-decree documents proving that the marital bond still exists, including the full Italian marriage record issued by the competent Comune, not merely a generic reference to the marriage.

Where do you apply?

The application is filed online only through the Ministry of the Interior citizenship portal. If you live in Italy, the case continues through the competent domestic authorities after the online filing. If you live abroad, the application is handled through the competent Italian consulate for your place of residence. Official instructions also make clear that the email address used in the portal functions as the applicant’s elected digital address for communications, so requests for additional documents, appointments, and notices are sent through the portal and related electronic channels.

How long does Italian citizenship by marriage take?

Italian citizenship by marriage is subject to a legal processing term of 24 months from the filing date, which may be extended up to a maximum of 36 months. This is the current timeframe reflected in official consular guidance for the procedure. In practice, some cases may still take longer to feel fully completed, especially where foreign documents, consular checks, or post-decree formalities are involved, but the official rule to state in the article is 24 to 36 months.

How much does it cost?

The main official government cost is the €250 contribution payable to the Ministry of the Interior. Additional costs depend on the applicant’s case and usually include translations, apostilles or legalization where required, certified copies, and other document-related formalities. These extra costs can vary significantly depending on the country of issue and the number of documents that must be prepared.

As for the €16 stamp duty, the rule depends on where the application is filed. For applications submitted abroad through Italian consulates, the €16 stamp duty is no longer required from 1 January 2025. For applications submitted in Italy, official guidance still indicates the €16 stamp duty within the domestic filing process. For that reason, the article should present the cost structure differently for Italy-based and consular applications abroad.

What happens after approval?

Approval of the application does not make you an Italian citizen immediately. After the decree is issued, the authority may request updated documents to confirm that the marital bond still exists and that the legal conditions remain satisfied. The oath must then be taken within 6 months of notification. Missing that deadline means losing the benefit of the decree. Citizenship takes effect after the oath is sworn.

Common mistakes that can delay or damage the application

The most common problems are not glamorous. They are bureaucratic, and they kill applications quietly:

• counting the waiting period from the wrong date;
• filing before the foreign marriage has been transcribed in Italy;
• uploading incomplete, expired, untranslated, or improperly legalized documents;
• using personal data that do not exactly match the birth certificate or foreign civil-status records;
• omitting prior residences or relevant background information;
• assuming the B1 requirement never has exceptions, or the opposite, assuming it can be ignored;
• reaching the decree stage after separation, divorce, or another event that breaks the legal bond before the required moment.

Practical tips

Start with the marriage registration issue first. If the marriage was celebrated abroad, make sure it has been properly transcribed in Italy before you build the citizenship file. Then request criminal records early, because in many countries they take time and may have short practical validity windows. Fill in the online application with obsessive consistency, because official instructions stress that names and birth details must match the foreign records exactly. Finally, monitor the portal and your email regularly, because official communications, requests for integration, and notices are sent through the digital system.

Conclusion

Italian citizenship by marriage is one of the most accessible legal routes to Italian citizenship, but it is not a shortcut and it is not automatic. The file must be built carefully, the waiting period must be calculated correctly, the marriage must be properly registered in Italy, the language rule must be handled correctly, and the online application must be consistent down to the smallest identity detail. Get those parts right, and the procedure becomes slow but manageable. Get them wrong, and the process turns into a bureaucratic ambush.
