Can an illegal immigrant become legal when she/he marry a U.S. Citizen even they're not using their real names?

No. Due to the "use method" of name change (even temporary name changes) this is not illegal *as long as*** you don't attempt to evade capture for crimes you've committed or attempt to defraud anyone.

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.
