Formation of highly-skilled migration policies in the Netherlands

Policy change in a certain area of life never happens rapidly without a reason. However the questions to be asked are: why are these changes? Why do policy-makers decide to generate a new declaration, new policy document regardiing this or that policy? The current paper is going to investigate and find the answers for the case of highly-skilled migration policies. I will conduct a research by the example of the Netherlands, a state with a long and contradictory immigration history.
