Sounds like a good analogy as to situation, except that the Turkish
workers in Germany, to the best of my knowledge, aren't migrants -
they're settled for the long term but barred from full rights of
citizenship. I think the term used is *gastarbeiter* - guest worker.
Even so, the analogy is imperfect, as the gastarbeiter is specifically
barred from full rights of citizenship, whereas the Torah's legislation
regarding the ger emphasizes granting a fuller array of rights than
might normally be expected.
