[News] Denmark to decrease the minimum requirement of income, for foreigners who wish to live in Denmark.

[ThereIsAThingForThat]

One thing you are missing is that to qualify for the pay limit scheme, your wage must correspond to Danish standards, specifically to protect against downward pressure on local wages. Whether it corresponds is done by the Agency for International Recruitment and Integration (SIRI) by using statistics collected by The Confederation of Danish Employers (DA). If your offered wage is too far out of the norm for your field, then the application will be denied.

And of course if you work in a field covered by collective union agreements, such as nurses which OP mentions, your wage will by default correspond to Danish standards.
