MY wife and i have been separated for years,do i need to answer all Marital questions on the application for naturalization?

Everyone should answer all the relevant questions on an application for naturalization. I do note that U.S.C.I.S. would be more concerned with questions concerning marriages where an individual has obtained permanent residence through the marriage or has sponsored other people for permanent residence through marriage.
