I was flying into Schengen Area (Denmark) from a non-Schengen country (Ireland), and with a non-EU/EEA passport of course I will get a passport stamp every time I cross the Schengen border. But this time when I fly-in I notice that my passport was not stamp with an entry stamp but a exit stamp instead. I guess the immigration officer has taken the wrong stamp to stamp my passport so this happen.
Since Ireland do not issue exit stamp, only with my passport there is no way of proofing that when I enter Schengen Area again, I know it wouldn't matter if I am just staying for a short period of time, but with some other recent visit I am pushing very close to the 90 days visa-free limit.
Would it be possible to go to the airport to get them to fix the stamp? Or is there some other way that I could take care of this problem?
