If your sister has filed a petition for your immigration visa, you must wait in your country of citizenship. That petition proves your intent to remain in the US, and you do not qualify for a tourist visa while you wait for your immigration visa application to be processed. Your sister cannot get you citizenship.
She can only petition for you to be considered for an immigration visa. Depending on your country of citizenship, current waiting time for a visa - IF approved - is 13-25 years.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
