The Dutch cabinet wants stricter requirements for non-EU labour migrants who are posted to the Netherlands through another EU member state. Minister Vijlbrief of Social Affairs (D66) says this route is being used more often and is intended to get around Dutch rules. Anyone who works in an EU country needs a work and residence permit, and the Netherlands is relatively strict compared with some other member states. That can make posting via another EU country attractive.
What this means if you are learning Dutch or new in the Netherlands: if you are a non-EU national planning to work in the Netherlands, check carefully which permit route applies to you. Being posted through another EU country is not automatically a simple alternative to a Dutch permit. Rules may become stricter, so confirm your situation with your employer or an official source such as the IND before making plans. For most people already living and working here legally, nothing changes immediately. The proposal still has to go through the usual political and legislative process.
