Although I do note that this question regarding an "indian community" seems to get asked much more often than any other nationality, which is odd.
I find it strange and troublesome that most Indians who relocate abroad express this desire to live in or near an Indian community. I am an Indian and HK is my sixth international relocation and I don't actively seek out Indians anywhere. I also find that when people from the Indian sub-continent travel abroad for business or tourism, they seek out Indian cuisine rather than the local cuisine. So much for open-mindedness.
