Essential connection guide
A transit visa can be required even when you never plan to leave the airport. The answer depends on your passport, connection country, route through the terminal and documents you already hold.
Start the 30-second check01 / YOUR ACTUAL ROUTE
The visa question changes when your passenger journey crosses a border.

Follow transfer signs and check whether your onward gate stays in the international transit zone.
Baggage, terminal changes, overnight closures or airport changes can force immigration.
You need permission for the transit country and final destination that matches the route you actually take.
02 / DO NOT GUESS
Rules are based primarily on nationality and travel document—not where you live.
Each country applies its own visa, waiver and exemption rules.
Passing immigration usually changes the permission you need.
Separate tickets or bags not checked through can force landside transit.
A valid visa or residence permit may create an exemption, but only under exact conditions.
