Applying for an airport transit visa in Poland
The Netherlands embassy in Warsaw doesn’t issue visa. Poland is part of the Schengen area. Therefore, citizens of Poland or persons with a valid Schengen visa or a residence permit for Poland do not need to apply for an airport transit visa for the Netherlands, another Schengen country or the Caribbean part of the Netherlands.
In case someone needs an airport transit visa, they can apply at the Luxembourg embassy in Warsaw.
