Working 1 year and studying after (EU citizen)

Visas, Permits, Passports and Naturalization

So I'll start working in about 4 or 5 months in Zurich on a normal full time contract. I'm from an EU country, the thing is after probably 1 year I'll start my university studies undergraduate (3 years) + master (2 years).

I just wanted to know if those years studying at the university will count for the C permit. While I was looking online for some info I've seen that if you work continuously 2 years after graduation they'll be counted, but what about my first year before my studies, will it also count somehow for C permit fast-track?

And also I don't know what tipe of permit will I be given when my work contract starts, since it's a normal contract I'm assuming it'll be an L permit or 1 year B permit. When this work year is done and I'm admited to the university I will ned to change the B / L permit to change the satatus for studying purposes?

Your study years will count if followed by two years of normal B permit.

The year before your studies doesn't affect whether your study years count or not. Whether that year would count on its own or not is irrelevant because you'll need two years post-study no matter what.

Yes, normally you'll have to go change your status to student and they will issue a new permit.
