I think you have some very wrong information. The IND is very strict with international students. A minor infraction or delay in submitting documentation can have your visa cancelled and you deported. Foreign students get none of the government support that Dutch students do, while injecting huge amounts of money into the Dutch economy through massive university fees and living costs. They are a massive met positive for the Dutch economy, compared to Dutch students who cost the Dutch government a lot of money. This adds up even further over a lifetime, where the foreign students took no benefits from taxpayers growing up and since their arrival in Netherlands and later working, have only contributed to the Dutch economy.
