Work permit info - Netherlands

re: Canadian musicians working in the Netherlands

Because they are citizens from Canada, they do not need a visa to stay in the Netherlands shorter then 3 months. Normally artists need a work permit to work in the Netherlands. Artists who would like to give incidental concert(s) within 4 weeks, do not need a work permit.
So if they would like to come to the Netherlands to give 1 concert they do not need a visa or work permit. If they will do more gigs, they need a work permit. For more information I refer you to the CWI (Centre for Work and Income). This organisation grants the work permits. Here it is: http://www.workpermit.nl/
