Questions to Khaled Hosseini

I would like to ask him:
-How is it like to be an Afghan living in the U.S.A particularly after September the 11th , and if he ever experienced any form of discrimination or prejudice based on his origins;
-If the Kite Runner is based on true events or if it is pure fiction;
-If the characters are based on real people;
-How did the Afghan community react to the novel and later to the film.
-Which are his personal views and opinions about the film. Does he consider it to be true to the novel?
