Actually, it was easier to emigrate from the USSR for Jewish men and women than for the rest of the nation due to refugee programs that US offers for minorities suffering persecution. I think other countries offer those two.

I am one of the people whose parents emigrated in 2004 as Christian refugees, btw. They had to prove they suffered from religious persecution (bible raids, not getting into colleges, etc).

The whole 'give me your poor and hungry' thing never really went away ;-)
