Finding an internship shouldn’t be too difficult in a city like The Hague. The city houses many different kinds of ngo's and (governmental) organisations such as embassies, multinationals and other international organisations.
Find an internship
The fastest and easiest way to find an internship vacancy is via an internet search engine. Do you understand a little bit of Dutch? Then try Stageplaza.nl or Indeed.nl. If you know what you want, contact the organisation you have in mind directly. Of course you can also seek help and advice from your study program.
