The Swiss Confederation is one of the safest and most economically prosperous countries in the world. Swiss citizenship grants full political rights, eliminates the need to renew a residence permit and entitles the holder to a Swiss passport.
Unlike holders of a residence permit, once a foreign national has obtained Swiss citizenship, they are no longer required to renew their residence permit. Prolonged residence abroad does not, in itself, usually result in the loss of citizenship for naturalised adults. Although the country’s legislation provides for specific grounds for the annulment, loss or revocation of citizenship status
Obtaining citizenship through naturalisation is a multi-stage procedure which, in most cases, requires professional legal support. Most foreign nationals must have resided legally in the country for at least 10 years before they can submit an application. The application is assessed at three levels, and the total duration of the process depends on the immigration category, the canton of residence and the workload of the authorities. Naturalisation in Switzerland usually takes 2–3 years.
Benefits of Swiss citizenship
1. Visa-free travel to 185 jurisdictions
According to one international ranking, in 2026 the Swiss passport was ranked among the top five most powerful passports in the world. It allows holders to cross the borders of a significant number of countries, including the UK, the US, Japan and the Schengen Area, either visa-free or via a simplified procedure.
2. The right to live and work in Europe
Swiss citizens may live and work in the countries of the European Union and the European Free Trade Association (EFTA) without a separate work permit, provided they comply with the registration requirements for their place of residence. With the exception of Liechtenstein, for which special rules apply.
3. Stability and a high standard of living
Switzerland is one of the safest countries in the world with a high standard of living. Along with Swiss citizenship, expats are granted political rights, including the right to participate in federal elections and referendums, as well as an unconditional right to reside in the country.
4. Dual citizenship and inheritance of status
As Switzerland recognises multiple citizenship, immigrants do not need to renounce their first passport. Furthermore, children of Swiss citizens usually acquire citizenship by descent, regardless of their place of birth, provided the conditions laid down by law are met.
5. Taxation
There is no federal inheritance tax in Switzerland. Spouses and registered partners are exempt from it in all cantons, whilst direct descendants are exempt in most cantons, although exceptions apply in certain regions.
Gains made by an individual from the sale of movable private assets, including shares and cryptocurrency, are generally not subject to tax at federal or cantonal level. An exception applies if the transactions are deemed to constitute professional trading or self-employment.
Who is eligible for Swiss citizenship?
Swiss law provides for several categories of immigrants who are eligible to obtain citizenship through naturalisation.
Long-term residents
Foreign nationals who have resided in the Swiss Confederation for a total of at least 10 years may apply for citizenship. Only periods of residence that meet the legal requirements are taken into account. Special rules apply to minors regarding the calculation of the period of residence.
At the regional level, applicants must also meet the requirement regarding the length of residence in a specific canton or municipality, which is usually between 2 and 5 years.
Spouses of Swiss citizens
Foreign husbands and wives of Swiss citizens are entitled to apply for naturalisation under a simplified procedure. The language requirements and integration criteria remain the same as in the standard procedure, but the required period of residence in the country is significantly shorter.
Children
A child automatically acquires citizenship regardless of their place of birth if:
- they were born to parents in a registered marriage, where at least one parent is a Swiss citizen;
- they were born out of wedlock to a mother who is a Swiss citizen;
- they were born out of wedlock to a foreign mother, provided that paternity by a Swiss citizen has been established;
- they are adopted by Swiss citizens.
Minors who are foreign nationals may also benefit from a simplified naturalisation procedure, provided they meet the conditions laid down by law.
Persons with special grounds
The law provides for special grounds for obtaining citizenship for certain categories of foreign nationals. These include:
- persons under the age of 25 whose families have lived in Switzerland for three generations;
- stateless children who have not yet reached the age of majority;
- persons who have previously lost their Swiss citizenship, for example, as a result of marrying a national of another state;
- persons who, as a result of an administrative error, consider themselves to be Swiss citizens and who, prior to the discovery of this error, duly fulfilled all obligations associated with citizenship, combined with a high degree of integration into the community of the municipality or canton.
Main ways of obtaining Swiss citizenship
In Switzerland, there are two main naturalisation procedures: ordinary and simplified. The choice of procedure depends not on the applicant’s preference, but on their personal circumstances and immigration route.
Ordinary naturalisation
This is the main route to naturalisation for foreign nationals who have been residing legally in Switzerland for a considerable period of time.
To apply, you must provide evidence of the required period of residence, successfully integrate into the local community, be proficient in one of the official languages, and fulfil all legal and financial obligations.
For standard naturalisation, an immigrant must hold a Permit C, have lived in Switzerland for at least 10 years, and have been present in the country for at least 3 years out of the 5 years immediately preceding the application. In addition, the applicable rules of their canton and municipality in Switzerland must be taken into account.
If the period of residence took place between the ages of 8 and 18, it counts double. However, the actual time spent in the jurisdiction must be at least 6 years.
Simplified naturalisation
Simplified naturalisation is available only to categories of applicants explicitly specified in the legislation. The length of the required period of residence in the country is determined by the grounds on which the application is made.
The most common categories include:
- Foreign spouses of Swiss citizens.
- Children of Swiss citizens who have not acquired citizenship automatically.
- Stateless minors.
- Third-generation immigrants who have grown up in Switzerland.
- Persons reclaiming lost Swiss citizenship.
The main difference between simplified naturalisation and the standard procedure lies not only in the shorter residence requirements, but also in the existence of a specific legal basis for submitting an application.
In most cases, the simplified procedure allows applicants to apply for citizenship earlier than under the standard naturalisation process. For example, spouses of Swiss citizens are entitled to apply after five years’ residence in the country. Furthermore, children whose Swiss parents have not applied for the same citizenship for their child as they hold themselves do not need to have lived in their parents’ home country for several years in order to be naturalised.
Requirements for applicants for Swiss citizenship
To be successfully naturalised, applicants must meet the legal requirements demonstrating their integration and their lasting ties to Switzerland.
Residence period
| Naturalisation | Total length of residence | Notes |
| Standard | 10 years | Any period of residence between the ages of 8 and 18 counts double. However, the actual period of residence in Switzerland must be at least 6 years. |
| Simplified | 5–6 years | The period specified in the table applies to spouses of Swiss citizens. For other applicants, the period of residence is determined by their immigration category. |
Regional requirements are also taken into account. Depending on the canton and municipality, you must have lived at the place of application for between 2 and 5 years.
Special conditions apply to spouses of Swiss citizens under the simplified naturalisation procedure:
- at least 3 years of married life together;
- at least 5 years’ residence in Switzerland, including the last year prior to applying for citizenship.
Foreign spouses of Swiss citizens who are permanently resident abroad are also entitled to apply for citizenship provided the following conditions are met:
- the marriage to a Swiss citizen has lasted for at least 6 years;
- the applicant has close ties with Switzerland.
Integration into Swiss society
When considering an application, the cantonal and municipal authorities assess the applicant’s level of integration and their participation in society.
Indicators that an applicant for citizenship has successfully become part of Swiss society include:
- compliance with the law and public order;
- respect for the values enshrined in the Swiss Constitution;
- knowledge of one of the official languages to the required standard;
- participation in employment, business, education or social activities;
- having strong ties with the local community.
Compliance with the law
When assessing an application, consideration is given to the extent to which the applicant respects the rule of law and public order in Switzerland. Particular attention is paid to the absence of serious criminal offences, as well as compliance with tax and financial obligations.
A history of serious criminal convictions, ongoing criminal proceedings and significant administrative offences usually stand in the way of successful naturalisation in Switzerland.
The authorities take into account the length of time since the offences were committed, their severity and their nature. Therefore, minor offences do not in themselves always preclude a positive decision, but may be taken into account in the overall assessment.
Financial situation
The ability to support oneself financially is part of the assessment of the applicant’s integration. Cantonal authorities may require proof of income, employment or other sources of livelihood.
The following may be taken into account in the assessment:
- employment or self-employment;
- professional qualifications and economic activity;
- the absence of a prolonged period of receiving social assistance.
Absence of debts
Before submitting an application for citizenship, the applicant must ensure that there are no financial or legal circumstances that could adversely affect the consideration of the application.
Potentially problematic factors include:
- ongoing debt recovery proceedings;
- significant outstanding tax liabilities;
- debts owed to the state.
The municipality or canton may request certificates confirming the absence of tax or social welfare debts. During the application review process, not only the existence of the debt is checked, but also its amount, how long it has been outstanding and whether it has been settled on time.
Language requirements
The applicant must demonstrate proficiency in one of the official languages of the Swiss Confederation: German, French, Italian or Romansh. The level of language proficiency is determined according to the Common European Framework of Reference for Languages / CEFR. Both oral and written skills are assessed.
Oral proficiency must be at a level of at least B1, which implies the ability to hold a conversation and express one’s own opinions freely.
For written language skills, it is sufficient to demonstrate a basic A2 level, which enables the understanding of written information necessary for living in Switzerland.
Proficiency can be demonstrated by means of a language certificate recognised by the State Secretariat for Migration (SEM), or by other means provided for by law, such as having received an education in one of the country’s official languages.
As with the other naturalisation criteria, language requirements should be checked taking into account the applicant’s region of residence.
How much will it cost the applicant to take the language test?
The cost of the language test depends on the type of certificate chosen by the applicant, as well as on the accredited examination centre. For example, taking the full fide test in 2026 will cost an expat 250 Swiss francs, which is equivalent to 269 euros at the current exchange rate.
The role of the canton and the municipality in naturalisation
The decision to grant citizenship is made as part of a three-stage procedure involving the municipality, the canton and the Confederation.
| Level | Role in the naturalisation process |
| Municipality | Assesses the applicant’s ties to the local community, their level of integration and their compliance with the requirements set at municipal level. |
| Canton | Is involved in the examination of the application and checks that the applicant meets cantonal requirements. Determines the procedure for naturalisation at regional level |
| Confederation | At federal level, it sets the requirements for applicants for citizenship and approves naturalisation in the cases provided for by law. |
Local requirements
In addition to federal regulations, applicants must comply with the requirements in force at their place of residence – in the relevant canton and municipality. Regional regulations may specify the application procedure, the minimum period of residence in a particular location and the specific details of the procedure.
Interview and integration assessment
In a number of cantons and municipalities, the naturalisation procedure includes an interview with the applicant. The aim of this is to assess the applicant’s level of integration, their connection to the local community and their familiarity with the particularities of life in the region. The procedure for the interview and the range of topics covered depend on the rules of the canton or municipality.
The applicant may be asked questions about their professional activities, financial circumstances, family and social connections. Preparing for the interview with Imperial & Legal significantly reduces the risk of failure, as our consultants are well versed in how the requirements are applied in different regions of Switzerland.
Documents required for citizenship
The main documents required from the applicant include:
- a passport or other form of identification;
- evidence of having met the minimum residence requirement in Switzerland and in the relevant canton and municipality;
- a language certificate or other document required by law;
- proof of financial means – documents relating to the applicant’s income, employment or business activities;
- information regarding compliance with tax and financial obligations;
- a certificate of no criminal convictions;
- documents regarding marital status (if required).
Before submitting an application, it is advisable to check the list of required documents with the relevant authority at your place of residence, as regional requirements may differ from federal ones.
Stages of obtaining Swiss citizenship
The procedure for obtaining citizenship may vary slightly depending on the region. However, in most cases, the process can be broadly divided into five consecutive stages. Here is how naturalisation is carried out with the assistance of Imperial & Legal’s specialists:
Initial consultation
Preparation
Submission of application and interview
Application review
Acquisition of citizenship
Timeframes for obtaining Swiss citizenship
The duration of the naturalisation procedure depends on the applicant’s category and the region in which they live. On average, the entire process – from submitting the application to the local authority to taking the oath in Switzerland – takes 2–3 years.
What factors affect processing times?
- the workload of government bodies;
- the specific procedures in a particular canton or municipality;
- the completeness of the documents provided;
- the need for additional checks;
To avoid unforeseen delays, it is important to objectively assess the prospects of naturalisation. Only a preliminary check of the requirements, combined with thorough preparation of the documents, can help minimise the risk of errors and additional requests.
Reasons for refusal and difficulties in the naturalisation process in Switzerland
Professional support from Imperial & Legal during the preparation stage enables potential complications to be identified in advance, the optimal application strategy to be selected, and the risk of refusal due to procedural errors to be reduced. Our agents have identified the five most common reasons for rejection by the immigration authorities.
1. Insufficient integration
Difficulties arise during the stage of coordinating the application with the local authority when the applicant:
- does not have strong ties to the local community within the commune or canton;
- is unfamiliar with the specifics of life in Switzerland;
- does not participate in the social or professional life of their region.
2. Insufficient language proficiency
Failure to meet language requirements, or the lack of documents confirming the required level of proficiency, may hinder successful naturalisation.
3. Financial difficulties
The following factors have a negative impact on the assessment of an application: tax arrears, outstanding financial obligations and frequent recourse to social assistance.
4. Breaches of the law
Criminal convictions, ongoing legal proceedings and serious breaches of the law may hinder the successful processing of the application or delay the process due to additional enquiries from the relevant authorities.
5. Errors in preparing the application
An incomplete set of documents or failure to comply with the requirements in force in the region where the application is submitted often leads to additional requests, which in turn prolongs the time taken to obtain Swiss citizenship.
