Foreign non EU students are allowed to work 16 hours per week in stead of 10 hours as of 23 May 2018. The employer still needs to apply for a work permit. Employers of students that are already in the possession of a work permit are as of 23 May also allowed to work 16 hours.
Another more favorable condition as of 23 May is that a work permit for students can be applied for if a student is registered at the education institution and has a residence sticker in his passport. Under the current conditions only a work permit can be applied for when the students was in the possession of a residence permit card for the purpose of study.
These changes come through because of the implementation of EU Directive 2016/801 which regulates amongst else the conditions for entry of students.
