Hi all, I've resigned late last year, and have been staying at my friend's place here in Zurich while I travel around Europe. As I'm planning to apply for a Master's program (which is in English) and a language course here, whilst I continue my tour , I noticed my 90 days limit is running near. Thus far I've only been to countries adjacent to Switzerland, which is within Schengen Area I believe. Will I be considered as overstayed if I were to continue my tour and apply for the courses?

Thanks in advance!!
