Ordinary naturalization in Switzerland follows a strictly defined federal path, but each canton — including Graubünden — adds its own requirements that vary from municipality to municipality. Those wishing to become Swiss citizens in the canton of Graubünden must first meet the federal criteria: at least 10 years of uninterrupted residence with a C permit (domicile permit). This term can be reduced to five years for citizens of the European Union and the European Free Trade Association. In addition to the standard count, Swiss law also allows double counting of the residence period between the ages of 8 and 18: one year of residence in that interval counts as two years for naturalization purposes, potentially reducing the overall term.

The federal framework of naturalization

In addition to the ten years of residence (or EU/EFTA regional variants), federal law requires uninterrupted possession of a C permit. This means that the applicant must not have suspended their right of residence, must not have committed serious criminal offenses, and must demonstrate a positive attitude towards Switzerland and its institutions. During the naturalization process, the candidate remains subject to federal and cantonal tax regulations: it is important to stay up-to-date on one's tax situation and regularly file the tax return according to the deadlines and forms prescribed by the competent authorities.

The federal procedure represents the first level of evaluation: it is a national screening that verifies basic eligibility. The C permit is not automatic after ten years; it is a residence title renewable every ten years, which can be revoked if the applicant commits crimes or is considered a threat to public order. Naturalization transforms the C permit into permanent citizenship: no expiration, no renewal, federal, cantonal, and municipal political rights.

In Graubünden, as in all Swiss cantons, the federal path is combined with specific cantonal and municipal requirements. The canton of Graubünden and its municipalities require language tests, integration tests, payment of naturalization taxes, and an evaluation of the candidate's civil conduct. These additional elements reflect the Swiss federalist principle: naturalization is primarily a cantonal-municipal decision, while operating within the basic federal framework.

Operational details

Specific requirements of the canton of Graubünden

The canton of Graubünden exercises decision-making authority over the naturalization of candidates, subject to compliance with federal criteria. This means that even after acquiring ten years of residence with a C permit, the candidate must still obtain the approval of the Graubünden authorities. The municipalities of Graubünden — particularly Chur, Davos, Poschiavo, and dozens of other centers — are responsible for the processing of the application, the collection of documents, the verification of conduct, and the final decision. Each municipality may have slightly different procedures, although all operate within the cantonal framework. It is therefore crucial to contact the naturalization office of your municipality as soon as possible, from the first year of residence with a C permit, to learn about the exact requirements and waiting times. The canton of Graubünden and its municipalities impose language tests in Italian, Romansh, or German (depending on the Graubünden region) and integration tests into Swiss society. These tests assess the candidate's level of knowledge of the local language and familiarity with institutions, constitutional values, history, and Swiss culture. Passing these tests is mandatory. Additionally, the canton requires the payment of naturalization taxes. The amount varies from municipality to municipality and is determined by the municipal law of Graubünden, not by a national federal tariff. Some municipalities apply a fixed fee, while others base the cost on a multiple of the candidate's income or assets. This cantonal differentiation reflects Swiss communal sovereignty in matters of naturalization: there is no uniform national price.

Municipal variability and access to rights post-naturalization

An often overlooked aspect is the verification of civil conduct. The canton of Graubünden and individual municipalities check criminal records, psychiatric medical records (if relevant), bankruptcy proceedings, and the candidate's behavior in the local community. Testimonies from neighbors, employers, or municipal representatives can influence the decision. Even minor violations (unpaid traffic fines, civil disputes, harassment complaints) can delay or block approval. This evaluation is subjective and depends on local authorities, which is why it is essential to maintain an impeccable reputation throughout the period of residence in Switzerland. Acquiring Swiss citizenship grants the new citizen access to the mandatory pension systems AVS and LPP, which are fundamental for social protection in case of old age, disability, or death. Automatic registration in the pension system is done through the employer (for the professional LPP regime) and the federal administration (for the basic AVS pension). These systems represent a central pillar of Swiss social security and will significantly influence future salary deductions and contributions made.

Key points

How to proceed: the naturalization process in Graubünden

Ordinary naturalization in Graubünden follows a process with specific steps. The candidate must first verify that they possess a C permit and have completed ten years of uninterrupted residence (or five years if they are a citizen of the EU/EFTA). Once these federal criteria are met, the next step is to contact the naturalization office of the municipality where they reside. There is no centralized cantonal office for naturalization: each municipality in Graubünden manages the applications of its residents independently.

The first step is to obtain the official naturalization application form. The form must be completed and signed by the candidate. Simultaneously, the applicant must gather supporting documents: residence certificate, original C permit, federal criminal record extract, certificate of good conduct from the municipality of residence, identity documents (passport or ID card of the country of origin), and income or real estate ownership certificates (the latter may be required if the municipality bases taxes on assets). Some municipalities also require a declaration of loyalty to Swiss constitutional values, although this is not mandatory at the federal level.

Once the application is submitted and the preliminary fee is paid (if required by the municipality), the investigation begins. The municipality verifies the data, contacts the federal authorities to confirm the C permit, obtains the criminal record, and summons the candidate for the language test. The language test in Graubünden varies by region: in the Italian-speaking areas (Poschiavo, Bregaglia) the test is in Italian, in the Romansh-speaking areas (Upper Engadine, Surselva) it is in Romansh, and in the German-speaking areas it is in German. The candidate must reach a B1 level according to the Common European Framework of Reference for Languages (CEFR). The integration test covers questions on Swiss history, rights and duties of citizenship, state secularism, and principles of direct democracy.

Timelines and conclusion of the procedure

The overall duration of the procedure varies: from six months to two years, depending on the workload of the municipal office and the speed at which the candidate provides documents. Once the tests are passed and the checks are completed, the municipality presents the application to the canton for final cantonal approval. Finally, the Parliament of the Canton of Graubünden votes on the naturalization decree (a traditional procedure in many cantons). Once this step is completed, the candidate receives the naturalization certificate and acquires Swiss citizenship.
