Visas: Tourists from Australia, Canada, Israel, Japan, New Zealand, Singapore, South Korea, USA and most of Europe only need a valid passport - no visa - for a stay of up to three months. EU nationals can enter for a stay of three months with just their national identity card or a passport expired less than five years ago. If you have a Schengen visa for one of the countries that is a member of the Schengen Agreement, it may be valid for the Netherlands also. Double-check with the embassies or consulates of the countries you're visiting though, to make sure the Schengen visa conditions still apply. Tourist visas can be extended for another three months maximum, but you'll need a good reason and the extension will only be valid for Belgium, not the Schengen Agreement areas. A three-month Belgian visa can take a little while to process, so don't leave it until the last moment; fees vary depending on the country in which you apply. Most types of visas also require that you show sufficient means to support yourself during your stay.
