Last year I have received Dutch 5-year MVV visa, came to the Netherlands and received my residence permit valid till year 2021. However, recently I checked my original country's passport and noticed that the until date is stated to be October, 2016 (whereas my Dutch residence permit is valid until August, 2021). I have 2 questions:
Does it mean that I am living illegally in the Netherlands?
If I leave EU, does it mean that I will not be able to come back, given that I do not have any other Schengen visas?
