Can I work anywhere in Switzerland or change jobs on a G permit?

EU/EFTA cross-border commuters enjoy the right to occupational and geographical mobility throughout Switzerland, which means you are not locked to a single canton or a single employer in the way some restrictive permits require. You can in principle change jobs and move your place of work across Switzerland while keeping your residence abroad and continuing to commute. Third-country nationals face more constraints, since their G permits are tied to stricter labour-market and cantonal conditions, so their flexibility is more limited.
