What this is about

Anyone who lives in Switzerland with a residence or settlement permit and transfers their domicile from one canton to another is carrying out not merely a move, but also a procedural step under immigration law. Swiss residence permits are in principle granted by the cantons — as provided by the Federal Act on Foreign Nationals and Integration (FNIA, SR 142.20) in Art. 33 FNIA; changing the canton of domicile triggers — depending on the permit class and nationality — either an obligation to register the arrival or an obligation to obtain authorisation from the new canton.

Art. 37 FNIA is the central provision. It distinguishes between:

  • the C settlement permit — an entitlement to change canton on mere registration of arrival,
  • the B residence permit of third-country nationals — an obligation to obtain authorisation from the new canton, and
  • persons of EU/EFTA nationality — free choice of canton of domicile based on the Agreement on the Free Movement of Persons EU/EFTA (AFMP, SR 0.142.112.681), Annex I.

This document describes the federal framework law and names typical cantonal differences. It is not a strategy paper for choosing an advantageous canton.

Changing canton is one of the most frequent sources of unnoticed procedural errors in Swiss immigration law. Three typical errors:

  1. Missed registration deadline — the obligation to register upon transfer of domicile follows from Art. 12 para. 2 FNIA; the specific deadline is set by the Ordinance on Admission, Residence and Gainful Employment (OASA, SR 142.201) in Art. 15 para. 1 OASA: registration of arrival in the new municipality of domicile within 14 days of moving in, and registration of departure in the old municipality of domicile within the same period. Many people only register after weeks or months, once they have concluded the tenancy agreement or taken up employment.
  2. Overlooked obligation to obtain authorisation for the third-country B — registration of arrival with the municipality does not replace the application for authorisation to the cantonal migration office (Art. 37 para. 1 FNIA and Art. 37 para. 2 FNIA).
  3. Uncertainty about permit transfer — the existing permit document does remain physically valid, but without a procedural step in the new canton, the renewal, an authorisation for gainful employment or a later application for family reunification may fail.

Consequence: only months later — for example when preparing the C permit or a naturalisation application — is the procedural error uncovered, with risks extending as far as refusal of renewal. This document is therefore designed to make the obligations visible before the move.

Typical situations in which the error comes to light

  • Permit renewal: at the next renewal, the old cantonal migration office discovers that the person has been living in another canton for months. The renewal is refused; at the same time, the new canton has received no application for authorisation.
  • Change of job with cantonal authorisation: a new work authorisation can only be issued by the canton of domicile. If registration of arrival in the new canton is missing, this blocks taking up the job.
  • Application for family reunification: the reunification of a spouse or child presupposes a correctly registered domicile. An unclear status delays the procedure or leads to a rejection.
  • Naturalisation preparation: the cantonal residence period is calculated from the correct registration of arrival. Late or missing registrations can postpone the entitlement by months or years.
  • Reduction of health-insurance premiums: this is granted at cantonal level. An incorrect domicile entry leads to a claim for repayment or loss of the entitlement.

Legal framework — the applicable provisions

Art. 33 FNIA — cantonal grant of the permit

Residence permits are granted by the canton in which the person takes up domicile. This means: the permit is territorially bound to the granting canton.

Art. 37 FNIA — change of canton of domicile (original wording, summary)

  • Para. 1: anyone who holds a short-term, residence or settlement permit and wishes to transfer their domicile to another canton needs a corresponding authorisation from the new canton.
  • Para. 2: persons holding a residence permit are entitled to change canton if they are not unemployed and no ground for revocation under Art. 62 para. 1 FNIA exists.
  • Para. 3: persons holding a settlement permit are entitled to change canton if no ground for revocation under Art. 63 FNIA exists.
  • Para. 4: a temporary stay in another canton (e.g. studies, hospital stay) does not require a new authorisation.

The entitlement in paras. 2 and 3 is legally significant: the new canton may refuse the change only if it finds a ground for revocation under the provisions mentioned. It has no free discretion to refuse a change of canton on grounds of expediency.

Art. 12 para. 2 FNIA and Art. 15 OASA — obligation to register arrival and departure

The obligation to register upon a change of domicile is governed by law on two levels: Art. 12 para. 2 FNIA establishes the obligation to report the arrival to the competent authority of the new place of domicile when the person transfers their domicile to another canton or another municipality; Art. 12 para. 3 FNIA delegates the setting of the deadline to the Federal Council, which makes it concrete in Art. 15 OASA.

  • Registration of arrival in the new municipality of domicile: within 14 days of moving in (Art. 15 para. 1 OASA).
  • Registration of departure in the old municipality of domicile: likewise within 14 days with the competent service of the former place of domicile (Art. 15 para. 1 OASA).
  • The obligation to register applies irrespective of the permit class — it also concerns C permit holders and EU/EFTA citizens.

(Note on delimitation: Art. 9 OASA concerns the short stay without authorisation and without registration and is not the provision governing the 14-day deadline upon transfer of domicile.)

AFMP Annex I — EU/EFTA citizens

Persons holding an AFMP permit (B, C, L EU/EFTA, Ci, EU permanent residence) have free choice of domicile within Switzerland. The change of canton is carried out as a mere registration of arrival; a separate authorisation from the new canton is not required. The formal obligation to register under Art. 15 OASA nevertheless remains.

The three regimes in detail

Regime 1 — C settlement permit (entitlement to change)

Anyone who holds a C settlement permit — regardless of nationality — has an entitlement to change canton (Art. 37 para. 3 FNIA). The new canton may refuse the change only if a ground for revocation under Art. 63 FNIA exists (e.g. conviction to a lengthy custodial sentence, lasting dependence on social assistance, serious integration deficits).

In practice this means:

  • Step 1: registration of arrival in the new municipality of domicile within 14 days.
  • Step 2: the municipality forwards the personal data to the cantonal migration office, which takes over the permit data.
  • Step 3: a new foreign national's permit card is issued; the old card becomes invalid.

The existing C status is not renegotiated. No integration assessment takes place, provided there are no indications of grounds for revocation.

Regime 2 — third-country B residence permit (obligation to obtain authorisation)

Anyone who holds a B residence permit as a third-country national is subject to the obligation to obtain authorisation from the new canton (Art. 37 para. 1 FNIA and Art. 37 para. 2 FNIA). The new canton independently examines whether the conditions are met:

  • no receipt of social assistance or supplementary benefits,
  • no existence of a ground for revocation under Art. 62 FNIA (deception of the authority, prolonged stay abroad, serious integration deficits, conviction),
  • where applicable, proof of language skills and proof of gainful employment or of other means of subsistence,
  • in some cantons: willingness to conclude an integration agreement under Art. 58a FNIA.

An entitlement exists — the canton cannot refuse on mere grounds of expediency — but it can refuse where a ground for revocation has been established.

Risk in the event of refusal: the person does not automatically lose their Swiss right of residence. They are obliged to return to the old canton of domicile — provided that its permit is still valid and no competing revocation ruling exists in the old canton. Otherwise, the refusal of the change of canton may indirectly lead to the end of the stay, because a take-up of domicile that has already occurred in the new canton de facto undermines the old permit.

This situation requires legal assistance as soon as it becomes apparent that the new canton might refuse. The document refrains from strategy recommendations.

Regime 3 — EU/EFTA citizens (free choice of domicile)

EU/EFTA nationals holding a B, C, L permit or EU permanent residence have, on the basis of AFMP Annex I, free choice of domicile in Switzerland. The change of canton is carried out administratively:

  • Step 1: registration of arrival in the new municipality of domicile within 14 days.
  • Step 2: the cantonal migration office takes over the permit data and issues a new permit card.
  • Step 3: no substantive examination of the conditions — the AFMP entitlement continues to exist as long as the bases of the permit (gainful employment, job-seeking, studies, family membership, sufficient financial means) are met.

Note: family members from third countries (e.g. the husband of a German citizen who holds Turkish nationality) derive their right of residence from the AFMP and follow the same regime as the primary AFMP beneficiary — not the third-country regime under Art. 37 para. 1 FNIA and Art. 37 para. 2 FNIA.

Special case — mixed family situation

Where a family household combines different permit classes (e.g. an EU citizen with a B EU/EFTA, a third-country wife with a B under family reunification, children with a B), each person's own permit class applies. In practice this means:

  • The EU citizen registers their arrival with the new canton (registration of arrival under the AFMP).
  • The third-country wife likewise follows the AFMP regime, since her permit is derived from the AFMP.
  • Third-country children under family reunification follow the same AFMP-derived regime.

But where the primary AFMP beneficiary has died or the marriage has been dissolved, the legal basis of the third-country person may shift to an FNIA permit (see Separation, divorce and residence permit (Art. 50 FNIA)). In that case, the change of canton will in future fall under the third-country regime of Art. 37 para. 1 FNIA and Art. 37 para. 2 FNIA.

The cantonal implementation of Art. 37 FNIA varies in the duration of the procedure, in the documents required and in the depth of the integration assessment. The practice notes below are qualitative; binding deadlines, document lists and language levels are to be obtained exclusively from the official website of the cantonal migration office concerned. Specific numerical values are deliberately not given here as long as they have not been confirmed at cantonal level.

Duration of the procedure

  • While the municipal registration must take place within 14 days (Art. 15 para. 1 OASA), the authorisation procedure at the cantonal migration office may, for third-country B nationals, take several weeks. The effective processing time depends on the canton, on the completeness of the documents and on the seasonal workload; a binding range is given by the cantonal migration office concerned.

Documents required (typically for a third-country B)

  • valid permit card,
  • current passport,
  • tenancy agreement or proof of ownership,
  • employment contract or proof of means of subsistence,
  • proof of health insurance (new cantonal domicile condition),
  • civil-status documents (where relevant),
  • proof of language skills (varies by canton — see below).

Competent cantonal bodies (points of contact, not exhaustive)

The following list names the competent cantonal authorities as a point of contact. Language levels and the question of whether an integration agreement is required are matters of cantonal practice and are to be checked via the respective official authority website — they are not stated here as fixed values.

  • VD (Vaud) — Service de la population (SPOP); tendency towards a pronounced integration assessment; an integration agreement under Art. 33 para. 5 FNIA, respectively Art. 58a FNIA, is possible in B cases.
  • ZH (Zurich) — Migration Office of the Canton of Zurich; standardised processing.
  • GE (Geneva) — Office cantonal de la population et des migrations (OCPM).
  • BE (Bern) — Migration Service of the Canton of Bern; bilingual practice (German / French depending on the administrative district).
  • BS (Basel-Stadt) — Bevölkerungsdienste und Migration.
  • ZG (Zug) — Migration Office of the Canton of Zug.
  • TI (Ticino) — Sezione della popolazione.
  • NE / FR / JU — competent cantonal migration authority of the respective canton.

Important warning: authority designations and requirements change. Before any change of canton, the official website of the destination canton must be consulted; the central federal overview is provided by the SEM thematic page on residence (see the frontmatter provenance.primary_sources). The notes mentioned here are not exhaustive.

Frequent practice differences that create unannounced procedural risks

  • Appearing in person at the counter: some cantons (in particular VD, GE) require personal appearance for handing over the permit — including for C permit transfers. Others (in particular ZG, some German-speaking cantons) accept processing by post.
  • Translated documents: for documents in a third language (e.g. a Turkish tenancy agreement), some cantons require official translations into the cantonal administrative language.
  • Confirmation from the old municipality: some migration offices require a departure confirmation from the old municipality of domicile as part of the new application — an obligation unknown in other cantons.
  • Production of the family record book / birth certificate / marriage certificate: in cantons applying high administrative strictness (in particular GE and VD), civil-status records are required even where the status has been unchanged for years.
  • Inquiry into outstanding taxes or debt-enforcement proceedings: some cantons inquire, as part of the integration assessment, about outstanding obligations. Important for context: tax debts or pending debt-enforcement proceedings do not in themselves trigger any ground for revocation under Art. 62 FNIA or Art. 63 FNIA — those provisions capture security and public-order grounds. Indebtedness can affect the status only indirectly, to the extent that it is weighed within the integration criteria (Art. 58a FNIA).

Procedure — the five steps

Step 1 — registration of arrival in the new municipality of domicile (within 14 days)

Mandatory for all permit classes (Art. 12 para. 2 FNIA in conjunction with Art. 15 para. 1 OASA). Required:

  • permit card,
  • passport / identity card,
  • tenancy agreement or accommodation confirmation,
  • proof of health insurance (on first registration in the new canton, the insurer may need to be changed).

Step 2 — registration of departure in the old municipality of domicile

Usually before the move. If registration of departure is forgotten, the old municipality may raise tax and fee claims.

Step 3 — permit transfer application (third-country B only)

For a third-country B, the application must be made to the new cantonal migration office. Registration with the municipality is not sufficient.

Step 4 — integration agreement (varies by canton)

In particular in VD, an integration agreement under Art. 58a FNIA may be required, setting out concrete integration measures (language course, vocational training, civic-values course).

Step 5 — issuance of the new foreign national's permit card

After approval, the new card is issued showing the new canton of domicile. The previous card becomes invalid and must be returned.

Timeline — a typical sequence

The following sequence is purely illustrative and reflects the order of the steps, not binding processing times. Example: a third-country B person moving from ZH to VD.

  • Before the move: tenancy agreement signed in the new canton.
  • Moving day: transfer of domicile.
  • Within 14 days: registration of arrival in the new municipality and registration of departure in the old municipality (Art. 15 para. 1 OASA).
  • Subsequently: application to the new cantonal migration office (in VD: Service de la population, SPOP) for permit transfer.
  • During the procedure: where applicable, a hearing, a request for further documents, where applicable an integration agreement.
  • After approval: issuance of the new foreign national's permit card; return of the previous card.

The effective duration varies by canton; delays due to incomplete documents or peak-season workload are frequent. Binding information on deadlines is to be obtained from the competent cantonal migration office.

Language as a cantonal difference

Switzerland does not have a single nationwide official language. When changing canton across the language boundary, a renewed language assessment may be required:

  • French-speaking cantons (VD, GE, NE, FR, JU, partly BE, VS): French A1, depending on the situation A2.
  • Italian-speaking canton (TI, partly GR): Italian A1.
  • German-speaking cantons (ZH, BE-DE, BS, BL, ZG, LU, AG, SO, SG, GR-DE, TG, SH, AR, AI, GL, OW, NW, UR, SZ): German A1, depending on the situation A2.
  • Romansh (GR, individual regions): the migration office generally accepts German.

The language levels required for the ordinary change of canton are not codified uniformly at federal level: the SEM publishes framework directives that the cantons apply autonomously within the integration criteria (Art. 58a para. 1 FNIA). The decisive language level is therefore to be checked via the official website of the destination canton.

By contrast, the language level for the early grant of the C settlement permit is laid down by federal law: Art. 62 OASA (para. 1bis) requires oral skills of at least level B1 and written skills of at least level A1 in the national language spoken at the place of domicile. Which evidence counts as a language-competence certificate is governed by Art. 77d OASA (including mother tongue, several years of schooling in the national language or a recognised language certificate).

A German examination taken in a German-speaking canton is not credited in a French-speaking canton if the cantonal language is a different one. For detailed questions on proof of language skills, see the cross-reference below to Proof of language skills (A1 / A2 / B1 fide) (in preparation).

What happens if the change of canton is refused

If the change of canton is refused — typically in the third-country B regime — the following legal remedies are available:

  • Objection / appeal to the cantonal administrative court or tribunal cantonal within 30 days of notification of the ruling.
  • Thereafter, an appeal to the Federal Supreme Court (provided that a legal question of fundamental importance arises — access is narrow).

Out of scope: this document provides no strategic advice on appeals. In the event of refusal, a lawyer is to be involved without delay. Clara refers to legal consultation and gives no prospects of success.

Factual consequences of a refusal

  • Obligation to return to the old canton: as long as the old permit is still valid, the person can return there. A de facto forced move, which may conflict with the tenancy agreement already concluded and the change of job.
  • Competing proceedings: if a revocation procedure is running in parallel in the old canton (e.g. due to receipt of social assistance), the refusal of the change of canton may trigger a chain reaction.
  • Employment relationship in the new canton: a work authorisation in the new canton is in principle not possible without domicile there. Taking up the job can be blocked.
  • Family separation: if the family has already moved, a temporary separation threatens — in particular where only one person fails to clear the authorisation hurdle.

The seriousness of these consequences underscores why the procedure with the new canton should be clarified in advance before the physical move, as soon as success is uncertain.

Loss of the C settlement permit — stay abroad vs change of canton

Under Art. 61 para. 2 FNIA, the settlement permit lapses automatically when the person leaves Switzerland without registering their departure — for both the residence permit and the settlement permit, after six months. By contrast, changing canton within Switzerland does not count as a stay abroad and therefore does not lead to lapse; rather, a change of canton itself constitutes a ground for the expiry of the previous cantonal permit in favour of the new one (Art. 61 para. 1 let. b FNIA) and requires registration of arrival under Art. 37 para. 3 FNIA.

Important exception: moving to the Principality of Liechtenstein counts legally as moving abroad. The Principality has its own residence regime; a Swiss C settlement permit lapses on a long-term departure to Liechtenstein and is not transferable by registration.

Anyone who is planning a longer absence abroad and wishes to retain their C settlement permit may, on application, obtain an extension of the lapse deadline (Art. 61 para. 2 FNIA; the implementing modalities are governed by the Ordinance on Admission, Residence and Gainful Employment, OASA, SR 142.201). Details lie outside this document — see the cross-reference to Stay abroad and loss of the C permit (Art. 61 FNIA) (in preparation).

Integration agreement Art. 58a FNIA — what cantonal practice shows

Art. 58a FNIA describes the integration criteria:

  • respect for the values of the Federal Constitution,
  • language skills at a demonstrable level,
  • participation in economic life or the acquisition of education,
  • observance of the legal order.

In the event of a change of canton with recognisable integration deficits, the new canton may conclude an integration agreement setting out concrete measures (language course, civic-values course, job-seeking). VD is particularly active here (convention d'intégration); other cantons use integration agreements more sparingly.

In the event of non-fulfilment of the agreement, the permit may be revoked (Art. 62 para. 1 let. f FNIA). The consequences are serious — an integration agreement is not a mere administrative act, but a binding obligation. See the cross-reference to Integration agreement (Art. 58a FNIA) (in preparation).

School for children upon a change of canton

School is a cantonal matter. Upon a change of canton, parents must:

  • register the children with the competent school authority,
  • where applicable, organise support for the change of language (e.g. moving from a Zurich German-language school to a Geneva French-language school),
  • for younger children: consider integration classes, remedial teaching or German-as-a-second-language (DaZ) / French-as-a-second-language (FLS) instruction.

Compulsory schooling typically begins with kindergarten (varies by canton; on average from age 4). No gap in schooling may arise — the responsibility lies with the parents.

Out of scope: detailed school advice (school comparisons, private-school strategy, gifted-child support) is not immigration law and lies outside SIP-v3.

Taxes upon a change of canton — in brief

Swiss taxes are organised federally. Upon a change of canton:

  • Withholding tax: the withholding tax on earned income is regulated and levied at cantonal level; upon a change of canton the applicable cantonal tariff may change. The modalities are governed by the law of the new canton of domicile.
  • Tax domicile: as a rule, the decisive factor is the domicile at the end of the tax period (31 December of the tax year).
  • Inter-cantonal double taxation: it is prohibited under the case law of the Federal Supreme Court on the prohibition of inter-cantonal double taxation.

Out of scope: SIP-v3 is not tax advice. This document merely names the existence of the tax dimension but gives no tax advice. For tax questions, a tax-advice service or a fiduciary should be involved.

Municipal citizenship and naturalisation impact

For later ordinary naturalisation (Swiss Citizenship Act, SCA, SR 141.0, in force since 01.01.2018), staggered residence requirements apply:

  • Confederation: a total of ten years of residence in Switzerland, three of them in the last five years before submitting the application (Art. 9 para. 1 let. b SCA; time spent between the ages of 8 and 18 counts double under Art. 9 para. 2 SCA, provided there are at least six years of actual residence).
  • Canton: a minimum residence period set at cantonal level of two to five years (Art. 18 para. 1 SCA; the specific duration is governed by the respective cantonal citizenship act).
  • Municipality: a minimum residence period regulated at municipal level (varies by municipality).

Effect of a change of canton with respect to naturalisation: a change of the canton of domicile may delay the fulfilment of the cantonal minimum residence period, since this is regulated at cantonal level. However, the jurisdiction rule of Art. 18 para. 2 SCA must be taken into account: where an applicant transfers their domicile to another municipality or another canton, the canton and the municipality of submission of the application remain competent, provided that they have already completed the examination of the naturalisation requirements under Art. 11 SCA and Art. 12 SCA. A change of canton therefore does not automatically affect the cantonal residence period in the same way at every stage of the procedure — the timing of the change and the stage of the procedure are decisive.

Out of scope: this document provides no strategic advice on choosing a canton in order to accelerate or avoid the naturalisation application. Such case-specific recommendations fall under the activity of a lawyer under the Federal Act on the Freedom of Movement of Lawyers (LLCA, SR 935.61) and lie outside SIP-v3.

Out of scope — what SIP does not do

SIP-v3 is an information platform, not a law firm. In the context of a change of canton, the following in particular applies:

  • No advice on the choice of canton for tax-related, naturalisation-related or permit-related optimisation.
  • No strategic advice in the event of refusal of the change of canton by the new canton — referral to a law firm.
  • No assessment of individual prospects of success in the appeal procedure.
  • No tax advice and no fiduciary activity.
  • No school or education advice beyond registration information.

SIP-v3 explains the law but does not represent anyone in an individual case: individual legal advice and representation are reserved to the activity of a lawyer under the Federal Act on the Freedom of Movement of Lawyers (LLCA, SR 935.61). For every individual question, an immediate referral is made to a lawyer or a cantonal advice service.
