@LovingFalloutLondon1954 moving continents was the hardest thing I ever did, but it mostly wasn't the visa acquisition itself that was the problem.
However, the visa I'm on is only available to people who have a technical university degree and a job offer from one of a limited number of Dutch businesses who are on the register as needing specialized foreign talent.
Such a job will almost invariably be conducted in English. English fluency is widespread, especially among younger people and in cities.
