Swiss residence permit: how long can you stay outside Switzerland?
Six months. If you leave Switzerland without deregistering, a B residence permit or a C settlement permit ends after 6 months abroad — and short visits back don’t stop the clock. You can ask to keep a C permit for up to 4 years, before the 6 months run out.
When do you need to be back in Switzerland?
Pick your status and the day you leave or left. You get the last day to be back before the limit runs out.
Swiss residence permit: the limits at a glance
| Status | Time away | How it’s counted | Past the limit |
|---|---|---|---|
| Residence permit (B) | 6 months abroad | From the day you leave; short visits back don’t interrupt it | The permit expires |
| Settlement permit (C) | 6 months abroad, or up to 4 years if you ask | From the day you leave; ask to keep it before the 6 months end | The permit expires |
| Short-stay permit (L) | 3 months abroad | From the day you leave; short visits back don’t interrupt it | The permit expires |
The 6-month rule for Swiss permits
Under Article 61 of the Foreign Nationals and Integration Act (AIG), a permit expires when you give notice of departure abroad — when you deregister. If you leave without deregistering:
| Permit | Expires after |
|---|---|
| Short-stay permit (L) | 3 months abroad |
| Residence permit (B) | 6 months abroad |
| Settlement permit (C) | 6 months abroad — or up to 4 years, on request |
Visits back don’t stop the clock
The implementing ordinance (VZAE, Article 79) says the 3 and 6 months are not interrupted by temporary visits, holidays or business trips to Switzerland. If you live abroad and come back for a week, the months keep running from the day you left.
Keeping a C permit for up to 4 years
On request, a settlement permit can stay valid for up to 4 years. The request must be made before the 6 months run out — ideally before you leave. It goes to the migration authority, which decides; there’s no right to it.
Worked example
You leave Zurich on 1 March 2027 to work abroad, without deregistering, and come home for two weeks in July. Your B permit expires after 1 September 2027: the visit in July doesn’t start the months again. With a C permit, you’d ask the canton to keep it before 1 September.

How FlySee counts it
FlySee doesn’t have a Swiss residence permit tracker yet. Its Log records every day you’re outside Switzerland and rebuilds past trips from your photos, so you can see when an absence began. The calculator above counts calendar months from the day you leave; because short visits back don’t interrupt the 6 months, count from the day you moved abroad, not from your last visit.
