Wait, but doesn't Denmark have the strictest immigration policies in the entire EU?

I don't understand. Are you suggesting deporting all migrants to improve the statistics to Denmark's level? But that's impossible in our legal system. We've been actively importing culturally incompatible foreigners for decades now, and many already have citizenship. You can't just strip people of their citizenship in an attempt to improve the statistics.
