Do I have to live in the same canton or commune for a minimum time before naturalising?

Swiss naturalisation operates at three levels, and the canton and commune set their own residence conditions in addition to the federal requirements. Typically you must have lived in the canton and the commune for somewhere between two and five years, depending on local rules.

This means moving shortly before applying can reset part of the clock. Because cantons may also add their own integration requirements, confirm the local residence period with your commune or cantonal naturalisation authority before you apply.
