Visa Information

Which visa do I need to travel to the Netherlands?

If you want to stay in the Netherlands for less than 90 days, you may need a short-stay Schengen visa. Whether you need a visa to visit the Netherlands depends on your nationality and your travel plans.

Possible visa requirement

You can see on Netherlands Worldwide whether you need a visa or not. You can also read there how to apply for the visa.

Even if you do not need a visa, you must still meet certain conditions in order to visit the Netherlands. These can be found on the website of Netherlands Worldwide.

Other types of visa for the Netherlands

There are also other types of visa besides the short-stay Schengen visa. One example is an airport transit visa, which you may need if you are transiting through a Dutch airport.
