In every major city you’ll find communities which will speak only English. But from my experience these are mostly “expats” staying for a few years and leaving again. If you like to stay forever and want to make friends which will be close for an extended amount of time I recommend naturally meeting people, no matter their language. Most Germans I know (Gen X and Millennials) speak sufficient English to converse. In a mixed group it might happen that you will switch languages and you’ll learn it naturally especially if you already have some basic skills.
This unlocked a core memory. We used to play it in the shared living room of my dorm.
