In general, Westerners don't colloquially classify rough ethnic groups by strict continent. Asian means East Asian and South East Asian (people with slanty eyes)
India, Pakistan, Sri Lanka etc. possess "Indians" or national identity (Pakistani, etc.)
Iran, Iraq, Jordan, etc. possess "Middle-Easterners"
Other areas are usually called by national affiliation (Kyrgistan, Tajikistan, etc.) are currently undecided and usually just called by national identity.
(I always found it unusual that folks from India wanted to be identified as "Asian" when that's not the colloquial meaning of the classification).
