I come to go eastern part of Germany for a year because of my father's study. But, I can't speak German at all. I'm scared of going to Germany without knowing German. Well, I know that I have to study German very hard. But I think I'll be any less worried if I have some opinions of my situation on this app..
Negative/Positive opinions are really OK!!

I think as long as you can speak english there won't be that many problems! For sure you should study german, but especially if you are going to live in a city, most people will speak english well enough to explain things to you or to hold a basic conversation :)
What will you do in Germany? Study? Work? And do you know which city you will live in?
I live in Heidelberg and there are many foreigners here, also many koreans because they study here. It depends on the city how many foreigners there are/ where the foreigners are from.
It might happen that you will move to a city and meet many other koreans lol
My boyfriend is korean and when he came here he even found a korean church in Heidelberg. I was surprised since this city isn't that big haha
