In my country (the Netherlands) there is help for expats to settle. Getting a job, house, etc. There's even a tax cut for expats if you have a specialized job. Denmark might have something similar, I'm not sure. Their language is a pain to learn though (not like my language is fun lol). But like the Dutch the Danish are very good with English, especially in cities. Getting a job while only speaking English is not a problem. Denmark is a beautiful and amazing country, with amazing people. But we have bitterballen.
