I am an Australian who has spent the last 85 days in the Schengen zone. Of those 85 days, 70 were in Switzerland and 15 were in Germany.
Today I got a working holiday visa in Germany under the youth mobility program, granting me 1 year in Germany as well as 90/180 days outside of Germany in other Schengen states.
My question is, if I were to travel to Switzerland tomorrow, for how many days could I legally stay there before having to return to Germany? I've found conflicting information online and have arrived at three different conclusions:
5 days, since I've spent the last 85 days in the Schengen zone and thus have 5 left out of my 90/180 quota
20 days, since my working holiday visa grants me 90 days outside of Germany per every 180 and I've only spent 70 outside Germany so far
90 days, since apparently a change of visa status "resets the counter"
Which of those conclusions is correct?
