&gt; E.g. you can visit the US with a German passport for 3 months for a holiday but it&#x27;s extremely difficult to get a visa to move there indefinitely.<p>You do realise that works the same way for everybody and US visa-free entry is not a residence permit right? For instance as a US citizen you&#x27;d get visa-free entry to Iceland or Japan or New Zealand but can only stay for 90 days.
