It is extremely difficult. First, at least get a college education. You have to have someone sponsor you, a citizen or resident alien, who is willing to support you for five years and having proof of the income to do so.
Mostly, that's done by marrying someone in the US. Rarely, if you have a unique skill, you can get a work visa. AT 18, that is very unlikely.
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.
