I am German and live near the Swiss border. My wife is Swiss. I always tell Germans: if you want to get a feeling for the life of an immigrant in Germany, go to a non-touristic region in Switzerland. It's definitely not open hostility, but many little things which quickly give you the impression that you are not welcome and seen as a threat. You are treated differently as soon as you are identified as a foreigner, and this treatment is completely independent of your own behavior.
My wife really enjoys talking to Swiss people in German first (she has no accent anymore), and if the reaction is hostile, she seamlessly switches to full Swiss German in mid-sentence. The reactions are often priceless.
