Moving, I'm not sure about the nationalities or races involved. The issue to me is, naive as I am, I assumed that a British child, with a British parent, should be allowed to live in Britain with his or her parents. The revalation that many such children must either be separated from their 'foreign' parent, or else be forbidden to live in the UK, is sad to me.
Especially when you consider trying to explain such a thing. "Oh mummy can't live with us. The government won't let her in because she is not European."
