western psychologists have very little clue as to how to deal with things like these.
It seems like a reasonable suggestion to me that people visit trained professionals rather than quacks, or people who will give advice or 'help' skewed by their own personal, perhaps fundamentalist, beliefs.
Curiously, psychology itself was quite mixed with religion in the past; in some places, it still is. I remember reading Polish psychology texts as a kid, quite a lot of them had serious Catholic undertones (and sometimes explicit references). Which is sort-of understandable when you can count on religion as being an important part of your average person's life.
There's not much of a culture shock. You probably think they lived captive or in some "iron curtain" regime. They know everything about Europe, the follow the same tv shows, they use the internet etc. Including poorer people.
They don't come because suddenly they were let free and can now experience the world for the first time. They come because they had a devastating war in their country, and they, sadly (for them), can no longer stay there safely.
