Well i'm not thinking that everyone's goal in life is to live in this country, because that is obviously absurd. On the whole a lot of asylum seekers tend to come from the middle classes etc, often the poor simply won't be able to afford to travel.
The fact is that the only thing we do know is...
Well they came here for asylum, that would kinda indicate that there is a 'situation' at home, if that situation changes they might need or be able to return...
I'm not saying that they've all gone home but, it would be a fair assumption to presume *some* of them have, don't you think...
