All of my interactions with German immigration have not only happened in Germany, but at an office in the town I was living in at the time: the initial residence permit application, the first renewal, and the renewal where the Beamterin (government employee) helpfully pointed out that as the spouse of a German citizen, I had been resident long enough to go ahead and apply for a Niederlassungserlaubnis (permanent residence; aka, German equivalent of a Green Card).

Six weeks and 255 Euro later, it was in my hand. I have to “renew” it every ten years, but that’s only because the card needs to match my US passport number (and means I don’t have to carry that book around); there’s no interview or document gathering.
