Reinstatement of Swiss citizenship

Reinstatement of Swiss citizenship is only possible for those who previously held Swiss citizenship but lost it through forfeiture, renunciation or, for Swiss women, by marrying a foreign national before 1992.

You have lost your Swiss citizenship and would like to get it back. You will find everything you need to know about reinstatement of Swiss citizenship and the general conditions on the website of the State Secretariat for Migration (SEM).

SEM: Reinstatement of Swiss citizenship

The SEM is responsible for handling applications submitted abroad at a Swiss representation.

- You submit your application consisting of duly completed, dated and signed forms and the required supporting documents to the competent representation.
- You pay the advance application processing fee – see under ‘Fees’.
- The representation invites you for a face-to-face interview to check a number of points, including your ties to Switzerland and whether you meet the other specific requirements.
- The representation sends the SEM the application file together with a report.
- The SEM issues its decision on the application, subject to appeal before the Federal Administrative Court in Switzerland.
- You are notified of the SEM’s decision.
- You can order a Swiss identity document if you are granted Swiss citizenship.

Your minor children are included in the application if:
- you have parental authority over them;
- they live with you;
- they give their written consent if they are aged 16 or over.

On request, the representation will send you the following documents, which you must return to it, completed in a Swiss national language, dated and signed:
- ‘Application for simplified naturalisation’ form in accordance with Art. 27 para. 1 SCA
- Information sheet on Art. 27 para. 1 SCA
- Declaration concerning respect for public security and order
- Authorisation to obtain information
- Questionnaire on close ties to Switzerland
- List of documents required for the application in accordance with Art. 27 para. 1 SCA
The following documents, including documents about respect for public security and order, must also be submitted – the representation can give you information about the documents which can be issued in your country of residence abroad:
- Extract from the register of convictions
- Extract from the debt collection register
- Tax certificate
- Confirmation concerning receipt or non-receipt of social welfare benefits
- Confirmation concerning record, or absence of record, of criminal offences in the case of minors
Please note:
- Documents that are not completed in full in a Swiss national language, dated and signed, or that are illegible, will be sent back to you.
- The originals of the foreign documents requested may not be more than three months old (six months for civil status documents) and must be certified by the competent foreign authority.
- Documents not in German, French or Italian must be accompanied by a certified translation into a Swiss national language.

Foreign civil status documents that have not yet been registered in the Swiss civil status register can be submitted together with your citizenship application.
The originals of the foreign documents may not be more than six months old and must be certified by the competent foreign authority.
Documents not in German, French or Italian must be accompanied by a certified translation into a Swiss national language.
The competent civil status authorities in Switzerland can separately charge fees for their civil status services (verification of foreign documents in order to register the civil status data in the Swiss civil status register), according to the Ordinance on Civil Status Fees (CSFO; CC 172.042.110), and have the fees collected by the Swiss representation.

If necessary, Swiss civil status documents (e.g. Swiss family certificate) can be ordered from the competent civil status authority in Switzerland. You will find the addresses of the competent civil registry authorities on the website of the Federal Office of Justice (FOJ): Responsibilities and authorities (German, French, Italian)
You can also order Swiss civil status documents via your local representation. Costs must be paid in advance.

After the representation has received your application, it will arrange a mutually convenient date for a face-to-face interview which will in principle be conducted in a Swiss national language.
You will be invited to come to the representation in person for the interview, accompanied by any minor children aged 12 or over who are included in the application.
The interview with the applicant (as part of the process a separate interview will take place with minor children aged 12 or over who are included in the application) will cover various points, including:
- close ties to Switzerland, in particular:
  regular stays in Switzerland (at least three stays of at least five days each in Switzerland in the past six years);
  knowledge of a Swiss national language;
  general knowledge about Switzerland (geography, history, politics, society, etc.) – see the ‘Links’ sections for useful information to help you prepare for the face-to-face interview;
  contact with Swiss nationals;
  reference persons who are resident in Switzerland;
- respect for Switzerland’s internal and external security;
- respect for public security and order;
- respect for the values of the Swiss Federal Constitution;
- participation in gainful employment or training/education;
- promoting and supporting the integration of family members, in particular:
  learning a Swiss national language;
  participation in gainful employment or education/training in the country of residence;
  participation in the social and cultural life of Swiss nationals.

The Swiss representation generally submits its report on the collected data to the SEM within 12 months (Art. 22 SCO).
The SEM generally rules on simplified naturalisation or reinstatement of citizenship applications within 12 months of receiving the application and the report on the collected data from the competent Swiss representation (Art. 23 SCO).
The Swiss representation must be notified of any change of address or any event affecting the civil status (marriage, separation, divorce, birth, death, adoption, etc.) during this period.

An advance fee is paid when the application is submitted. It is paid in the currency stipulated by the Swiss representation at the current exchange rate. The fee must cover the following and does not include any fees charged separately by the civil status authorities for their services:

For further information, please contact the relevant Swiss representation in your country of residence.

Important

Swiss law allows dual citizenship. You can in principle keep your original citizenship. Acquisition of Swiss citizenship may, however, result in loss of your original citizenship if the law of your country of origin requires it. Relevant official information can be obtained from the authorities of your country of origin.
