Where is the my buddy DaKing when you need him...
But seriously... I think you need to clarify your statement "Countries Where There Are Hmong".
What constitutes being there? Do you mean visited? Going to School or higher education? Refugee or immigrated to said country? Just vacationing? As TheKing would put it, it depends.
Places I have visited but I don't know if it meets your definition: Brazil, Peru, Cambodia, Taiwan, India, England.
I know there are Hmong students in North Korea and I personally know of Hmong people currently working in Israel and Saudi Arabia. But again, does this meet your definition.
