It&#x27;s not just foreigners, it&#x27;s everyone in Germany. I&#x27;m not that familiar with the details though. No such thing is required in most of the West I think. In practice, an ordinary life leaves an ample paper (and digital) trail, but you can legally live &quot;off the grid&quot; if you&#x27;d like.<p>On the other end, the US is pretty unique in that you don&#x27;t have to notify the government that you&#x27;re leaving the country. I believe recent laws actually authorize an exit-tracking system, so that might be coming to an end unfortunately.
