I’m confused about how exactly the visa situation works. I know I can only stay for 90 days out of a 6 month period but I’ve seen some posts that say “in a calendar year”. Thus, my question is what if I stay for October, November, and December, then January through March. It’s more than 90 days but would that time period restart with the new calendar year? (Fyi, I’m trying to stay in Switzerland.)
Other possibilities I’ve though about but which I’m not sure are possible are staying in Switzerland for 89 days then become a student and getting a student visa.
Or, another thought was to stay in Switzerland for 89 days, go to Eastern Europe/North Africa/outside Europe for 90 days, then return. If I do this, I would assume I need to provide Switzerland with proof of my flight itinerary to a place outside of Europe before leaving (so they know I’m not trying to stay for 6 months) or would this not be necessary?
