I am a Lebanese citizen traveling from Beirut Lebanon to Zagreb Croatia with a 3-hour layover in Warsaw Poland. I hold a multiple-entry Schengen visa issued by France that I have never used before (valid for the period of my trip). The rules of Croatia state that I can enter the country with a valid multiple-entry Schengen visa. I have 2 questions here:
Should my passport be stamped by a Schengen country before I am permitted entry to Croatia?
Will my passport be stamped in Poland (in and out)?
