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?
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.
