Silvia,
I agree with you and on top of that there is an enormous price to pay by coming here without the family. The emotional distress has an enormous negative impact on the individual and his family.
Nobody ever warns newcomers of that and nobody measures how much harm the situation causes to expats!
For that and for the avoidance of being abused (as so many others) and considering that he works in avery good company back home, I would advice JP to stay where he is.
