You are Hmong no matter where you are in this world, even if you don't speak, write, or can read it. You can dye your hair, wear contacts, become a transgender, live like white, black, other asians, animal or insects, marry someone who is not Hmong, but what you cannot get rid of is the blood in you.
So with that said, you're Hmong. The thing that will make you stupid for being Hmong is if you don't claim yourself as one. The End. Kthxbye!
