Actually she wasn't an orphan at all she lived In an orphanage because her parents were poor after the tsunami so she didn't want to leave her parents! But still smart girl for not going :)
She would be rich and has better chance to be famous... then she could start talking about her country and found some charity, when she could contribute with her own (or Kardashian´s) money and someone would listen to her, because she would be the adopted child of Kardashian.
She looks too smart, to throw away her goals, but this would be the possibility too. Anyway I think that Kim K. would support her, because it will let her look better, that she has child that support charity and would sopport it too... But it's another possibility too.
The girl actually refused to go with her because her mother is still alive and she is not available for adoption. She also said that she likes Kim and would like to visit her.
*tee hee*
