I planned a trip to Europe earlier but was denied by the French border authorities. I was told that I had already spent 90 days in a 180-day period, and had overstayed by a few days. It was not my intention to do this; I completely misunderstood the definition of the duration of 90 days. I thought I could stay 90 days with every entry.
I was told that my visa is still valid, that I can still enter the EU with the same visa. I have a one-year Schengen multiple-entry visa, valid until December 2017.
Because there is a entry/exit stamp crossed-out, will the border authorities challenge me when they see this 'denied entry' stamp, or will I be allowed to enter as usual?
