National Coordinator counter-Terrorism and Safety (NCTV) is working on a blacklist with Islamic (hate) preachers: those who are on this list cannot get a visa for the Netherlands. Reasons to be put on this list are for example the preaching of intolerance or preaching anti-integration and anti-democracy messages. Even preachers that already received a visa can have it revoked.
The list comes in reaction to a charity event in the city of Rijswijk where some radical preachers were invited, which caused a lot of commotion in the Netherlands. The visa of three preachers were there upon revoked.
In January this year the Contact body Muslims and Government already stated to work on a black list. However this list has not the above restrictive force, but is mainly advisory.
