Times have changed, and now anyone is free to try to go where they think it will be better. And many start gathering documents, take them to a translation bureau, stand in lines to get them notarized, and finally appear at the consulate of their dream country.
However, before spending money on document translation and notarization, it is worth thinking about important things.
First, about where and how you will live, at least initially, which will inevitably be needed for adaptation. Don't even dream of buying an apartment right away, unless you are an underground millionaire. Renting a home is also not cheap. And you need to eat, drink, dress, and use transport. Good if you have a decent sum, or your own housing in Kyiv or Moscow. You can sell it (and whether it's worth doing, we'll think about a bit later) and exist abroad quite comfortably for some time. But money has a way of running out…
Therefore, secondly, you need to assess your prospects in finding a job. And also think about what that job is likely to be (of course, if you have an offer from a Western company, you can set these thoughts aside). It's understandable that sitting at home in a warm kitchen, it's pleasant to think that you would take any job just to get on your feet. But that's all just illusions.
Third, how well do you know the language? Well? At your home company did you do technical translation with a dictionary? Oh, you have a TOEFL certificate? Nevertheless, you need to be prepared that you will have to learn the language, and seriously. Are you ready for that? Fourth, fifth… there is a lot to think about. But probably the main thing is this: Are you sure you will be happy there? Or at least that you will be happier than at home? After all, you will be an emigrant for the rest of your life, a person of lower grade, and only your children, perhaps, will become full citizens of that country. You will have neither friends nor close ones, and if something happens to those who stayed home…
Not sure? Then don't rush to cut ties. Leave your housing here as a 'backup airfield.' What if homesickness turns out to be stronger than you! And think: maybe things at home are not so hopeless after all?
