There is a lot of information about the 180/90 rule, but nowhere can I find what happens AFTER the first 180 days calculated from the first entry?
Let's say I have multiple entry visa for a one year period, and I was in Schengen for 30 days within the first 180 days period. After those 180 days (after my first entry), am I allowed to enter at all? Or just 60 remaining days, or maybe even another 90, till the expiration of visa?
