He could pass up Hispanic/ Latino rather easily. Pics gives me the impression the person regularly smiles a lot even when he doesn't look at a camera. He reminds me of some Persians before. Person could pass up in South or Central Asia.
You are getting very close to the answer when you mentioned the region of South or Central Asia. Interesting how he reminds you of some Persians even though he is not one.
You mentioned before from another thread that that the footballer and some Afghans could pass up as Hispanics/ Latinos, maybe we are looking at another Afghan.
