Guy in OP looks typical South Indian but can pass all over South Asia. I would place him in Kerala if I had to guess his ethnicity, looks like a lot of Malayalees I’ve seen.
The other other two people posted here like the guy and the girl (especially the girl) are typical Indians you see in America, like more than 75% of Indians I’ve seen in America look just like them, people I went to school with and have worked with as well as neighbors, people you see in public lmao. When I think of Indians those are the 3 people I think look most like Indians and are good representations. If you ask them they’ll tell you they feel close to Pakistanis even if in reality they have more in common with Sri Lankans and Maldivians.
