These Asian countries are giving dual citizens an ultimatum on nationality -- and loyalty

Anna was born with the right to dual citizenship, because she has a Japanese mother and American father. She spent her life traveling between both countries, and says she felt deeply connected to the two cultures.

(CNN) — Anna was born with the right to dual citizenship, because she has a Japanese mother and American father. She spent her life traveling between both countries, and says she felt deeply connected to the two cultures. But Japan requires those with multiple passports to pick one by the age of 22 -- an impossible choice for Anna, who requested a pseudonym for privacy reasons. "I'm mixed race, I've lived both in Japan and the US, I speak both languages, I am completely split down the middle in terms of my identity," she said. "It's like asking someone whether they love their mother or father more. It's such a cruel question."
