Whether you clear immigration at Zurich Airport (ZRH) in 2026 depends entirely on your origin and destination. If you are traveling between two Schengen Area countries (e.g., Berlin to Zurich to Madrid), you will not pass through passport control because you are staying within the common travel zone. However, if you are arriving from a non-Schengen country (like the US or UK) and connecting to a Schengen destination (like Rome), you must clear Swiss immigration in Zurich, as this is your official "entry" into the Schengen zone. Conversely, if you are flying from a non-Schengen country to another non-Schengen country (e.g., New York to Zurich to Dubai), you can remain in the "Airside" transit area (Gates D or E) and bypass immigration entirely, provided your bags are checked through. For "self-connecting" passengers who booked separate tickets, you will likely need to clear immigration to collect and re-check your luggage.
