"Being a guest is good, but being at home is better!" - one of the most famous proverbs, but nevertheless not everyone agrees with it. Everyone chooses for himself his home and place where he wants and will live. For example, in Germany. If you really want to move there, but are afraid that you will not be able to settle down, then do not worry! The main thing is to remember some rules.
First thing you need to do is learn the language. English is enough for a start. The more you interact with people, the faster you will remember and get used to new accents, words and phrases. However, although the overwhelming majority of Germans speak English, their primary language is German. Therefore, in order to understand well what they are talking about, master at least the very basics of the German language. And speak! Speak as much as possible! And then the language barrier will disappear for you. But if it's really difficult for you, then try enrolling in German or English courses right in Germany.
Tradition and morale. To get accustomed to the soul, you need to have common values, respect customs, and also celebrate the holidays together. This is necessary so that your life is not boring, so that you have fun not only alone, but also with other residents. Whether or not to follow this is up to you.
Take care of your life before moving: find a place to live. Buy or rent an apartment. Try to do this in advance, and if it does not work out, then solve this problem as soon as you arrive! If you have children, then the problem of housing must be solved all the more immediately, so as not to torment the children.
Think about where you will be working. You can always take a certain amount of money for the first time, but what will you do when the money runs out?
If everything suits you, then you can easily draw up documents and go to live in Germany! This is just an ordinary country with ordinary people who, perhaps, at one time also decided to move to live in it.
