I agree with tinkerbell, don't make it hard for your kid...the language difference is a big problem already, and of course the school curriculum, we have different methods of teachings and your kid might feel he is a cast out in there, plus culture diff he might find it hard to understand.  Better to sorround him with filipino kids also...my son goes to school for the first time he's in PSD nursery level and it was difficult on the first week he cries when i leave him there. It's better to leave your kid with someone you know who can talk in same language...

As for me, i am comfortable talking to his teacher and I can explain my concerns further....
