A Swiss work permit B is the residence permit that lets a foreign employee live and work in a canton for a limited, renewable period. For most transferees it is the document that follows entry into the country. For your HR or mobility team, it sets the rhythm of the whole assignment: when the file is prepared, who pays for what, and when renewal must be on the calendar.
This page explains the B permit as a category. It does not replace the guides on the full permit system or on the application steps. It gives you the frame you need to write a policy and brief an employee.
What the B permit is
The State Secretariat for Migration (SEM) groups Swiss authorisations into three families. Short-stay permits cover stays of less than a year. Annual permits are limited in time. Settlement permits are unlimited. The B permit belongs to the middle family: it is a limited residence permit, issued for a stay that is expected to last, and it can be renewed.
For EU and EFTA nationals, the SEM lists the titles as L (short-term stay), B (resident), C (settled), Ci (resident with gainful activity, for people linked to foreign representations) and G (cross-border). The B permit is therefore the "resident" title. It sits above the short-term L permit and below the C permit, which is the settlement title (State Secretariat for Migration (SEM)).
Two points matter for your policy:
- The permit is personal. Your employee holds it. Family members hold their own.
- The permit is issued by the canton where the person lives, with the federal level involved in some cases. The canton is the practical counterpart for every step after arrival.
Where B sits among the categories
Use the table below to brief a transferee who has heard the letters but not the meaning.
The table is a map, not a ruling. The exact length of each permit, and the conditions for moving from one category to another, depend on nationality and on the canton. The authorities decide each case, so your policy should avoid fixed promises on duration.
EU/EFTA nationals and third-country nationals
The route to a B permit differs by passport.
EU and EFTA nationals benefit from the free-movement agreement between Switzerland and the EU. The agreement shapes the rules for access to the labour market and for the permit titles listed above. In practice, the file is usually lighter and there is no annual quota for this group. Your employee still has to register and receive a permit. See hiring or transferring EU/EFTA nationals for the free-movement route.
Nationals of other countries (often called third-country nationals) face a stricter admission system. The employer usually starts the process, the canton assesses the file, and the federal level may need to approve it. Quotas and priority rules can apply. Our guide to Swiss work permits covers every category, and the page on third-country quotas covers the allocation.
If your population is mixed, build two tracks into your policy. A single process note for a British, an American and a German transferee will be wrong for at least one of them.
What changes for a transferee
Moving from a home-country status to a B permit changes several things at once. HR should brief the employee on each.
The legal basis for staying
Before arrival, your employee may have no right to live in Switzerland. The B permit creates that right, for the purpose stated in the file. If the purpose changes, for example a new employer or a new role, the permit may need to be updated. Ask the canton before the change is announced.
The link to the employer
A permit issued for work is tied to that work. A transferee who changes employer inside the group, or whose role changes significantly, may need the authorities to review the file. Treat any internal move as a permit question first and an HR question second.
Residence registration
After arrival, the employee registers with the local municipality (Gemeinde in German-speaking areas). The permit and the registration go together. Your relocation checklist should place both near the start of the first weeks.
Family members
Spouses and children have their own files. Their rights, for example whether they can work, depend on the category and on the basis of the application. Do not assume that a family permit follows automatically from the employee's. Our page on the residence permit for transferees and their families sets out the family angle.
Taxes and insurance
The permit changes where the employee is tax resident and which insurance duties apply. This site does not give personal tax or insurance advice. The rules are general, and the effect on one person depends on their situation. Ask for a specialist review through the relocation request.
The order of steps for an employer
The sequence below is a working model. Your canton may add steps.
Do not let your employee book a one-way move before you know the decision route. Entry rules differ from permit rules. Ask the competent authority what is needed before travel.
Renewal: what to plan for
A B permit is limited, so renewal is part of the lifecycle. The authorities set the length of each permit and the timing of the renewal request. This site does not state those periods, because they vary and because they should be confirmed with the canton.
What you can plan without a number:
- Keep a permit calendar. Record the expiry date for every transferee and every family member. Our relocation calendar is meant for exactly this.
- Start early. Ask the canton how far ahead of expiry a renewal request is accepted.
- Keep the file consistent. If the employee's role, address or family situation has changed, the renewal file should say so.
- Confirm who files. Decide in the policy whether HR, a provider or the employee submits the renewal.
For more on renewing, see renewing Swiss permits. If your employee moves home within the country, read when an assignee changes canton before the move is booked.
From B to C
The C permit is the settlement title. It is unlimited in time. Moving from B to C depends on nationality, on the length and quality of residence, and on conditions the cantons check. This site does not give the periods. For a third-country transferee on a fixed assignment, the C permit is rarely the planning target. Do not describe it in a policy as an entitlement.
Common mistakes in transferee policies
- Promising an outcome. The authorities grant permits. A policy that says a permit "will be" issued creates a liability.
- Using one process for every nationality. EU/EFTA and third-country files differ.
- Forgetting the family. Spouses and children need their own steps.
- Ignoring the calendar. An expired permit is a compliance event, not an admin delay.
- Treating registration as optional. It follows arrival and is tied to the permit.
- Quoting a duration from memory. Ask the canton.
Checklist for your file
- Confirm whether the employee is an EU/EFTA or a third-country national
- Confirm the category the file should request
- Gather the employee and family documents the canton asks for
- Decide who submits the file and who pays for it
- Brief the employee on the registration step after arrival
- Put the expiry date in the permit calendar
- Record any change of role, employer or address that needs a review
- Ask a specialist to review the tax and insurance effects

Where we fit
We are a matching service. We work with leading relocation companies in Switzerland and, depending on your request, put you in touch with the one that fits your need. We do not file permits ourselves. If you want a specialist to look at one case, use the request at the bottom of the page. Our pages on immigration support and relocation services in Switzerland describe what such support covers.
Frequently asked questions
What is a Swiss work permit B?
It is the limited residence permit, the "resident" title in the SEM's list. It allows a foreign national to live in Switzerland, and when the file says so, to work. It is renewable and sits between the short-term L permit and the settlement C permit.
Is the B permit a work permit or a residence permit?
It is a residence permit. When it is issued on the basis of employment, it also covers that work. That is why people call it a "work permit B" in everyday speech.
How does B differ from L?
L is a short-stay permit, for stays of less than a year. B is a limited residence permit for a stay expected to last longer. The authorities decide which fits the file.
How does B differ from C?
C is the settlement permit and it is unlimited in time. B is limited and must be renewed. The C permit has its own conditions.
Who applies for the B permit?
It depends on nationality and on the file. For many third-country transferees, the employer starts the process. For EU/EFTA nationals, the route is lighter. Confirm with the canton who files.
Does an EU/EFTA national need a B permit?
For a stay of the relevant kind, yes: the SEM lists B among the titles for EU/EFTA nationals. Free movement shapes the conditions, but a permit is still issued.
Is there a quota for the B permit?
Quotas apply to some third-country categories, not to EU/EFTA nationals in general. See the page on third-country quotas for the allocation rules.
How long is a B permit valid?
The length is set by the authorities and varies with nationality and the file. This site does not state a period. Ask the canton for the exact validity in your case.
How do we renew a B permit?
The holder, or the employer on their behalf, asks the canton to renew before expiry. Ask the canton how far ahead the request is accepted and which documents it wants.
What happens if the permit expires?
An expired permit is a compliance issue. The right to stay or work may be affected. Act before expiry and speak to the canton at once if a date is missed.
Can the employee work for another employer on a B permit?
Not automatically. A permit issued for work is tied to that work. A change of employer or role may need the authorities to review the file.
Does a group transfer count as a change?
It can. An internal move between group entities is still a change of employer in legal terms. Treat it as a permit question before it is announced.
Do spouses get their own permit?
Yes, family members have their own files. Whether the spouse may work depends on the category and the basis of the application.
Do children need a permit?
Yes. Children also hold their own permit, linked to the family file. Ask the canton what is needed for each child.
Must the employee register after arrival?
Yes. Registration with the municipality (Gemeinde) follows arrival and goes with the permit. Place it early in your relocation checklist.
Can the employee enter Switzerland before the permit is issued?
Entry rules and permit rules are separate. Ask the competent authority what is allowed before travel. Do not book a one-way move on assumption.
What documents are usually needed?
Typically the work contract, identity documents and employer declarations, plus family documents where relevant. The canton publishes the exact list, so confirm it before you start.
Can a B permit lead to a C permit?
It can, under conditions that depend on nationality and on the quality of residence. These conditions are not stated here. They should be confirmed with the authorities.
Does a B permit give the right to change canton?
Not as a formality. A move to another canton generally needs the authorities to be informed and may need approval. Read when an assignee changes canton first.
Is there a minimum salary for a B permit?
Salary rules can matter in some files. Our page on salary thresholds for permits covers the question without personal advice.
Does the B permit affect tax?
It affects residence, and residence affects tax. The effect on one person depends on their situation, so ask a specialist rather than relying on a general page.
Does the B permit affect health insurance?
Residence brings insurance duties. The details depend on the person. A specialist can review the case through the relocation request.
Can HR guarantee that a B permit will be granted?
No. The authorities grant permits. A policy should state that the application will be submitted in good faith and not that the outcome is certain.
What if the file is refused?
Ask the authority for the reasons and the options open to you. A specialist can advise on the next step for the case. Do not move the employee until the position is clear.
Where can I check the official categories?
The SEM publishes them on its residence pages. The links are in the sources below.
