You don't understand what refugee status imparts - it's legal asylum, granted by DHS/ICE and the State Dept., from a real or perceived threat of serious injury from another country. Those who are automatically granted asylum once inside the US include North Vietnamese, North Koreans, Cubans because were they to return they'd probably be murdered like so many unfortunate predecessors. Apparently Donald Rumsfeld was litigated for having marched a Gitmo detainee out of the frying pan, into the fire in such a way.
Einstein was something of a refugee; Germany's loss, our gain.
