Here's a scenario:
- Say I am in a country in the Schengen Area on a residence permit that expires Jan 1, and have been here for a few years continuously
- I leave the country to go live somewhere else outside of the Schengen Area on Jan 1
- On Jan 15 I want to come back to visit this same country for a week
When does the 180 day window start for me? In particular, can I come back on Jan 15 in this scenario without violating the rule or does the window lookback 180 days flat to even when I had a valid residence permit? That would seem odd to me, but I can't find any language explicitly allowing this. maybe because it is a somewhat rare case.
