A binational couple moving to Switzerland rarely arrives under a single legal framework. One partner may hold an EU/EFTA passport and the other a passport from outside that area. Your policy must then treat two files, not one.
This page sets out the decisions that fall to your HR or mobility team. It explains the general rules. It does not assess an individual couple.
Why nationality drives everything
Swiss law distinguishes two regimes. Nationals of EU/EFTA states follow the route created by the agreement on the free movement of persons (ALCP). Nationals of third states, meaning outside the EU/EFTA, follow the rules of the Foreign Nationals and Integration Act (LEI). The State Secretariat for Migration (SEM) describes both on its admission pages.
In a binational household the assignee's nationality usually sets the main route. The partner's nationality then decides how the partner joins. The two are not always the same, so your transferee should not assume that one permit covers both people.
Detailed conditions for each regime, such as qualification criteria or priority for resident workers, are set by the authorities and change over time. Confirm them against the SEM guidance or through a specialist before you commit to a start date. The permit finder and the guide on how to get a Swiss work permit give the wider picture.
Three typical constellations
Assignee from a third state, partner from the EU/EFTA
The assignee follows the third-state route, which depends on the employer's application. The partner holds an EU/EFTA passport. How that partner's own status interacts with the assignee's route depends on the rules for EU/EFTA nationals and on the canton. Do not assume the partner is simply a "dependant". Ask the migration office how the file will be handled.
Assignee from the EU/EFTA, partner from a third state
The assignee follows the free movement route. The partner's right to join depends on the family rules attached to that route and on documents that prove the relationship. The detailed conditions need checking case by case before your employee signs a lease or gives notice abroad.
Both partners from third states, with different nationalities
Both follow third-state rules, but each passport may require different documents or consular steps. Family reunification then applies, as described below.
Family reunification for third-state partners
For third-state nationals, the SEM and cantonal guidance describe reunification of the spouse and of unmarried children under 18. The cantonal leaflet from Schwyz summarises the points that matter for planning.
- The request must be filed within 5 years.
- For children over 12, the period is 12 months.
- Late requests need major family reasons.
The legal footing differs by status. For the spouse of a Swiss citizen or of a permit C holder, the law gives a right. For the spouse of a permit B holder, the authority has discretion, so there is no right to reunification. Conditions on housing and financial means also apply and vary. Verify them with the canton.
Your policy should therefore state who files, who pays, and who tracks the deadlines. Missed deadlines are an employer-side planning failure, not a family one. See permits for spouses and children for the next level of detail.
Employment rights of the partner
Many couples ask whether the partner may work from arrival. The answer depends on the partner's nationality, the permit granted and the canton's practice. This page does not state a general rule, because none applies to every case. Ask the cantonal migration office what the permit allows before the partner accepts a job offer or resigns abroad.
If your policy offers spouse career support, word it as help with the search, not as a right to work. A specialist can then review the couple's situation through the request at the bottom of the page.
Sequencing the move
Arrival duties for both partners
Each partner must register with the municipality (Gemeinde) of residence. The usual period is 14 days, though it may vary by municipality or canton. Bring a valid ID, the residence or work permit and proof of health insurance. The portal ch.ch and the cantonal sites list local requirements.
Health insurance is compulsory for everyone living in Switzerland. Each person must take out basic cover no later than three months after taking up residence. If the deadline is met, cover applies from the date of residence, and premiums are due retroactively. If it is missed, cover starts at affiliation, a surcharge may apply for an unexcused delay, and the cantonal authority may assign an insurer. Treat this as a task for each partner, not only for the assignee.
For the full order of tasks, see the moving to Switzerland guide and the relocation calendar. If children are joining, read moving with children. Common errors are collected in common mistakes.
Checklist for the HR team
- Record the nationality of each partner and each child
- Identify the regime that applies to each person
- Assign an owner for the partner's permit file
- Note reunification deadlines in the case tracker
- Ask the canton what the partner's permit allows regarding work
- Brief the couple on registration and insurance duties
- Book settling-in support for the first weeks
Frequently asked questions
Does one permit cover both partners?
No. Each adult needs their own status, and the route depends on each person's nationality. The assignee's permit does not automatically extend to the partner.
Can the partner join later?
Yes, in many cases. For third-state nationals, the request must be filed within 5 years, and within 12 months for children over 12. Late requests need major family reasons.
Is family reunification a right?
It depends on the status of the person already in Switzerland. The law gives a right to spouses of Swiss citizens and permit C holders. For permit B holders, the authority has discretion.
Can my employee's partner work immediately?
It depends on the partner's nationality, permit and canton. Ask the cantonal migration office before the partner accepts a role. A specialist can review the case through the request at the bottom of the page.
Who must take out health insurance?
Every person domiciled in Switzerland, including each partner and child. Cover must be arranged no later than three months after taking up residence.
Should the couple register together?
Each person registers with the municipality, usually within 14 days, though this varies. Bring ID, the permit and proof of insurance.
Does the employer have to handle the partner's file?
The law does not set this out as a duty. It is a policy choice. State in your policy who files, who pays and who follows deadlines, so the couple is not left to guess.
