I am staying in Poland for a conference. Afterwards, I was planning to stay for pleasure. I purchased the tickets and applied for a visa, and got 7 days visa. Yet my tickets were issued from the 7th till the 16th which contradicts and exceeds my stay for over 2 days.
My question is what are the calamities and consequences (if any) if I stayed for extra 2 days even though my visa expires.
