Voting in Dutch elections
If you are abroad when elections are held in the Netherlands, you can – under certain conditions – still vote.
Voting while abroad
You can vote in Dutch elections, even if you are abroad when they take place. But the way you cast your vote will be different (by post or by arranging for someone to vote by proxy on your behalf). And you may have to register in advance. This all depends on whether you live abroad, or are just travelling.
See government.nl for more information on voting while abroad (this site is in Dutch).
