That is what happen to my uncle, for 10 years he can only work as factory worker...part time too. In SU he was mechanical engineer. Israel government pay for half his apartment, only way he could get one.
If I come to Russia what percentage of the rent of my apartment will be paid for me by the Russian government? Engineers need to be fluent in the local language in any country and need to know how to apply for work.
Immigrants from Communist countries take quite a long time settling down in Israel, especially if they are older, because they are unfamiliar with the way that capitalistic countries work. In Russia they were looked after by the state, found jobs and allocated apartments, as far as I can gather.
