Discussion on NIS is very interesting and informative if we all take it positively.

I would like to add my comment on the other aspect of this debate that at the same time when English parents are worried about their child's language problem to be in a class with majority of non-English students, it is wish of the parents of non-English parents to send their children in English schools to improve their English. That's why they pay big amount for fees in these English schools. And the only way to improve other language skills is to give students an environment where they can get chance to speak more and more.

If an English child is going to learn Arabic, he can learn only when he is surrounded by Arabic class fellows and if a non-English child wants to learn English, he can learn only when that environment is available to him where he can learn to speak English. Mixup of nationalities makes it possible.

Life is name of compromises. If you have many choices, opt your own and if you don't have, don't blame.
