Clarification on nationality
During my journies around the interwebs, I've encountered some speculation on her nationality/ethnicity. So I basically thought I'd make a quick post clarifying a few things (or perhaps, making things even more unclear). Her father is Nepalese, and her mother Ukranian. She has lived in Katmandu and the Ukraine, but from the age of 13 to 19 she lived in Norway. She then went to the UK to study acting.
As for her actual nationality, most of her family have gained Norwegian citizenships - but as of this date, Amrita Acharia have not yet acquired this herself. Her application for citizenship has actually been turned down by the Norwegian government, and as a result (because of labour-exchange laws), her work permit in Great Britan (enabling her to work on Game of Thrones), is actually in danger. I, at least, have not seen any clarification on this subject as of yet. What small media recognition she has recieved in Norway, however, mention her as being Norwegian.
I know for a fact, btw, that she has worked on season 2 of GoT.
