I am a travel agent in the U.S. and will be traveling in Europe, independently (not with any tour or cruise).
My husband, sister-in-law and I will be having a long layover in Istanbul on our journey to Sarajevo from Bucharest, connecting through Istanbul on September 23 (7 hours).
Do we need a visa to leave the airport during that time if we just want to get into the city to have a meal and do some shopping:) also, what is the cost and the process to purchase one?
