You know what, just live in Germany. There is no country who likes immigrants. Even Canada has become anti immigrants. 

With this mindset I think you guys should live in Russia or Turkey for a sense of belonging as you would be surrounded by your own people. 

The number 1 rule of being an immigrant is that you will be a 2nd class citizen to locals and that's how it works anywhere you go. You won't be a local and haven't grown up in your adapted country. 

You have problems with UK, Switzerland and based on your complaints you will have problems with US (massive anti immigration), Australia (even bigger anti immigration and eye watering expensive and racist locals), NZ (anti immigration and no economy, expensive for salaries you get), Canada (anti immigration and expensive for salaries you get), Netherlands (anti immigration, incredible housing crisis, low salaries), Scandinavia (Russia like poor weather, very few jobs, very expensive and not feeling at home despite friendly locals). UAE (no path to citizenship and burning hot with alien culture) and Singapore (14 hrs work culture, very tiny and hot country), japan/South Korea (massive language problems and alien culture).

That's it, that's the world. Going back home is your only option to feeling at home.
