Yes, you read it right, starting January of 2013, all immigrants who will do the dutch language course will pay the said course by themselves. The Gemeente (City hall) will not pay for it anymore. It is a new law. The over all course estimation will be around 5000 euros (or lower).
I am lucky that I did the course and got the diploma before this law. I think you can get a studiefinanciering (money finance for studying) in IB GROEP. This money is payable after 6 months of getting the inburgering diploma. For more info, check the website of DUO (Dienst Uitvoering Onderwijs). Hope this article will help you.
***This law is not applicable to all immigrants, some immigrants are NOT REQUIRED to do the said course.*** Check the website of IND or DUO for more informations.
