I have a query regarding cooling off period for visa type "Work permit up to 120 days". My job requires me to travel to Zurich repeatedly (every year), hence it is important for me to know the below details.
What is the cooling period in Zurich canton to re-apply for the same visa type ("Work permit up to 120 days")?
Does the 12 months cooling period start after I enter Switzerland or after I leave from Switzerland?
E.g. Last time I was in Switzerland on a 120 days work permit starting on 20th Dec 2017 and left from Switzerland on 18th April 2018. With this information when can I reapply for the same Visa type "Work permit up to 120 days"?
