    Overview of French Citizenship by Marriage

    Foreigners may apply to become French citizens either by declaration (claiming citizenship as they are legally entitled to it) or by decree (applying for citizenship), provided they fulfil eligibility and documentation requirements.

    French citizenship by birth, marriage, or ascendancy comes under the declaration route, while French citizenship by naturalisation is obtained by decree.

    If you are a foreign national married to a French citizen, you may apply to become a French citizen yourself by declaration if you meet certain specific conditions, which may vary depending on how long you have been married to your French citizen spouse and how long you have been residing (or have resided in the past) in France with them. The citizenship application process will also vary slightly depending on whether you are currently living in France or abroad.

      The above list is not exhaustive by any means. The French authorities may ask for additional documents depending on your situation so you may wish to reach out to an immigration expert for assistance on what exact paperwork is needed for a successful application.

      Application Process for French Citizenship by Marriage

      The application process for obtaining French citizenship by marriage is through the declaration route. Applying for French citizenship via declaration is usually more straightforward than applying by decree.

      Prepare a Dossier

      You will need to put together a dossier with all the required information and documents. It is preferable to arrange the documents in the same order as referred to in the official instructions. While preparing your dossier, you should check whether the official documents from your home country need to be legalised or require an apostille.

      This is one of the most time-consuming and cost-intensive steps in your citizenship application process. You are advised to take legal advice since getting your documents in order is critical to the success of your application. Call +44 (0)333 305 9375 to speak with our team of legal advisers at Total Law.

      Submit Your Application

      You will need to submit your completed and signed application form along with the required supporting documents at a French government centre, known as a platform. You will have to submit your documents either in person or send via post if your platform offers that facility.

      If you are outside France, you will need to get in touch with your local French embassy/consulate to submit your documents.

      Attend an Assimilation Interview

      You will have to attend an assimilation interview along with your French spouse. This interview will be conducted at your regional platform by prior appointment and you must bring your ID documents to the interview.

      An interviewer will thoroughly check your credentials and ask you various questions regarding your life in France and why you want to become a French citizen. The goal is to ascertain the level of your integration into French society and culture. The interview will be conducted in French and you will not be allowed an interpreter.

      You must prepare well for your interview as the assimilation interview can be a rigorous process and may last up to 90 minutes. Your local gendarmes or police may also pay you a visit at this stage, which may or may not be by appointment.

        Citizenship by Marriage Application Review

        Post your interview, your platform authorities will review your application and supporting information, and your declaration of French nationality will be registered if you meet all the conditions to become a French citizen. They may also send your file to the Ministry of Interior with comments for further review within six months from your date of interview.

        If you are applying from outside France, the concerned French embassy/consulate will forward your file along with their comments to the ministry within six months.

        If your application is accepted, your local prefecture (or embassy/consulate for applicants abroad) will provide you with a copy of your declaration of French nationality by marriage. Please preserve this document as proof of your nationality and proceed to ask for a national identity card and/or a French passport.

        The authorities may take up to a year to refuse to register your declaration or two years if they want to initiate a procedure opposing your acquisition of French nationality.

                  If your application for French citizenship by marriage is refused or opposed, you will be informed of the refusal decision and the reason(s) thereof in writing. You have a maximum of six months to appeal the refusal decision from the date of receiving the refusal letter.

                  You may lodge an appeal with the Ministry of the Interior within two months if they are opposing your application, or with the administrative courts of appeal for a final review within six months if your registration has been refused.
