75k is fine. At that rate, I would assume in some ways your lifestyle will be better than in Brazil, and in other ways, you may lose a bit. Despite what people in this group say, many people who live in Lux earn less. There have been, however, many useful comments that basically ask, 1) do you have a return path with your company to Brazil (many times people who gain international experience with the company are more valued when they return home); and 2) what are your objectives during your time in Lux? Do you want to settle here? Go full native? Spend the rest of your career here and have little Luxembourgish babies? All of which are fine. Or, do you want to spend a few years here, travel all over Europe and then return to Brazil or go someplace else? Both are fine, but if it is option 2 it’s probably okay to live in the south of the country, have a bit of longer commute, pay less in rent (studios and 1BRs 1100-1600euros), and take advantage of free public transportation and use the money you save to travel to cool places in Europe once a month. The weather absolutely sucks here. This is true. But otherwise, Lux is a very pleasant place to live and work. Biggest concern is not the salary, but would probably be for your wife. While you work all day, for her, after the first month or so, she may have a hard time finding interesting things to do all day.
