maybe there are some people that may look somewhat like you in Asia,
but indeed like everybody, ur caucasian and I think 99% of the people will
believe so too.
Now be aware, just a stupid example, me and my familie is from Belgium, but when my
father was in the middle east for buisiness, a lot of people tought he was from
Libanon because of his dark short hair and his small mustache.
It was funny because he doesn't look from that region at all, he also has only roots here in Belgium itself so biologically it doesn't make sense.
It is more seen with appearance and things like that.
So even if your roots are 100% from ur own country, in other countries they might think different. But to mistake you for being Asian or not, I think that chance is a lot smaller.
