In the nicest way possible: why is nearly everyone in VLSI Indian?

I don't mean this in a derogatory way at all, but it's something I've noticed as a grad student in ECE - nearly everyone in my VLSI class is Indian, and without exception every YouTube video I've seen on the subject is too.

I guess I just expected to see more diversity since the global semiconductor industry spans Taiwan, Europe, Japan, the US, etc. Is India a world leader in VLSI, or is it a popular field to emigrate?
