Are you someone who has left their country of birth to move and settle somewhere else, or who is thinking of doing so in the future? What led you to take that decision, or what is making you consider it? What have your experiences been until now, and what do you expect and hope for in the future?
I originally intended to specialize in Software and Game Development
potentially Web Development too, since I wish to go to that side; but I wonder if I might have to specialize in Data Science and AI instead, because the world seems to go towards that direction when talking about the importance of tech-related degrees. There seems to be some techies in Lemmygrad though, so maybe they know better than us on this subject, so maybe they can chip in with a more informed opinion.How do I start investigating though? How did you learn that Norway had enough professionals from your field? And I'd like to know what you meant by "how willing the country would be to accept and treat well-specialists of my field of work".
You are ideally searching for two things: that your destination is in need of professionals from your field, and that they are willing to give you a pay high enough that you can live a comfortable life there. There are quite a few instances in which a country needs specialists but they are unwilling to offer a good pay in return.
The way that gives you the best results at obtaining information is at the same time the one that is most direct: ask to the people from the place how easy it is to get a job of your field and how is life there working in your field. There are several communities on the internet dedicated to people of a country in particular: in Reddit you can find them easily, and most of them can easily respond to you if you ask in English.
