Living in Sion is a different proposition from living in Zürich or Geneva. Sion is the capital of the canton of Valais, set in the Rhône valley and dominated by two hilltop castles. For your transferee, it is a smaller, regional base with a full cantonal administration on the doorstep.
This page is written for the HR or mobility manager who has never placed an employee here. It covers the setting, language, housing, schools, transport and the first steps with the authorities.
Where Sion sits and who lives there
Sion lies in the central Rhône valley, surrounded by vineyards and mountains. It is the seat of the cantonal government and administration, which matters for permit and registration questions.
The permanent resident population was 37,844 people in 2025 (Federal Statistical Office, FSO). Of these, 11,696 were foreign nationals, or 30.9% of residents (FSO, 2025). Your transferee will therefore not be an isolated newcomer.
Language: what to tell your transferee
The canton of Valais is officially bilingual, French and German (Swiss Confederation, Presence Switzerland, 2024). The dominant everyday language of the city itself is not confirmed by an official statistic, so do not assume it for your policy.
Ask the local authority which language a given procedure runs in. Then plan language support accordingly. Language lessons for the employee and any accompanying partner are a policy decision for you, not a legal requirement.
Housing: what the figures do and do not say
The FSO publishes no average rent for the city of Sion alone. The nearest official figure is the canton of Valais. In 2024, the average net rent for all dwelling sizes was CHF 1,227 per month (FSO, structural survey). Treat it as an order of magnitude only.
By size, the same cantonal source gives these averages for 2024 (FSO):
- one room: CHF 740;
- two rooms: CHF 1,028;
- three rooms: CHF 1,260;
- four rooms: CHF 1,459;
- five rooms: CHF 1,745;
- six rooms or more: CHF 1,862.
Net rent excludes service charges. Advertised rents in the city can differ from these cantonal averages.
On 1 June 2026, the vacancy rate for the canton of Valais was 1.04% (FSO). A city-level rate has not been verified, so do not infer one from this cantonal figure. A tight market is a planning risk for any move date.
Ask the specialist partner to explain how Swiss rental files work. A landlord or letting agent (régie) will usually want proof of income and a rental deposit. Your employee cannot view flats easily from abroad, so build time for a search trip or a managed search into your policy. Our home search service page explains the managed option.
Schools and families
No verified list of international schools in Sion could be sourced. Do not promise a place in an English-language school to a transferee with children.
Public schooling follows the cantonal system, in the local language. Ask the cantonal authority which school your employee's address falls under. The school choice guide helps you frame the options by family situation.
Getting there and getting around
Transport links, journey times and travel passes have not been verified for this page. Check train services with the national railway and local services with the regional operator before you commit to a commuting assumption.
Do not state a journey time to your transferee until it has been checked. If the employee will commute to another city, compare the cantonal capital with that city first. The city comparator is a useful starting point.
The cantonal migration office
The competent authority is the Service de la population et des migrations (SPM) of the canton of Valais. Its details are on the SPM website, and the State Secretariat for Migration (SEM) lists every cantonal authority.
Permit rules differ for EU/EFTA nationals and for third-country nationals. The authorities, not your company, decide each application. Use the permit finder to see which route applies, then ask a specialist to review the individual file. For service scope, see immigration support.
The first days in Sion
Arrival is a sequence, not a single event:
- register with the local commune, as the local rules require;
- confirm the permit position with the cantonal office;
- take out mandatory health insurance;
- open a bank account;
- enrol children at school.
The relocation calendar shows the order. For the practical settling-in work, see the settling-in service.
