Either your wife doesn't trust you or she has another reason. The other reason could be that she herself is not a US citizen or it could be that she has tax problems and doesn't want to file returns. Before you leave the country, you should make sure that you can file for a divorce in your home country in case she chooses not to follow through.

If your home country won't allow you to file for a US marriage to a US spouse, then file in the US. It's cheap and easy if there are no kids or assets. You cannot force her to file for you, and pressuring her will make matters worse.

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.
