Oh I see. I didn't want to use Asian as I specifically meant someone from Japan, China and so on as opposed to somewhere like India (don't get me wrong, I'd be happy with an Indian doctor as well). Oriental's always a term I've used.
Someone from Indian and Pakistan could be described as South Asian.
That's what my wife prefers. Call her Subcontintental--as I have seen on the internet--and she is likely to slug someone.
