Who cares about citizenship? I know Japanese expats. They don't speak Dutch and they keep their Japanese passport. They just get a permanent residence and everyone is happy.
We all know that there are two groups of foreigners: people from first world countries and the rest.
Ofcourse the Netherlands constitution says that you have to treat everyone equally but that's just hippie talk.
Are you sure about the Dutch part? AFAIK in almost all EU countries you have to have at least B1 language for permanent residency.
