Istanbul is one of the most accessible metropolises in the world, connecting Europe and Asia, providing easy access to nearly 70 countries and 2 billion people within four hours. It does not require a visa for many countries, or if required for some countries, it can be obtained within minutes via the internet, at the airport, or at the border. Istanbul is an excellent city to host such a significant event with its historical richness, unique venues, and facilities.

IFOS 2026 Istanbul will be held at the Istanbul Congress Center (ICC) located in the Istanbul Congress Valley. The Istanbul Congress Center, situated in the heart of Istanbul Congress Valley in the city, within walking distance of approximately 30,000 hotel rooms, is an exceptionally excellent and modern structure with all features.
