I have a short question about the 90/180 day visa calendar. My girlfriend has visited the Schengen area according to below schedule:
Arrival 28 July 2017
Departure 10 October 2017
So she basically still has 15 days left from that previous stay.
She now however is in compliance to the requirements needed to start the procedure to grant her 5-years stay, but I am struggling to understand
- when the new 180 days period start for her
- if these 15 days can be carried over (are still to be used) in the current 180 days.
My basic question is: What is the earliest date for her to come again, and then stay for another 90 days (in a new 180 days period)?
