Once upon a time I heard that the world is divided in french and british legal traditions. Denmark took over the french principles, while the US took over the british. For that reason, I expect a jump to require plenty of retraining, including a whole new language.

But there will still be international companies that will need help and explanations of US weirdness. Go look for those, like Novo Nordisk, Velux, Danfoss, Vestas, Maersk and others...
