I am a legal permanent resident of the US. I had gotten married before I came here but my wife have never been to US. That means we lived apart for some years, and our marriage has faded. However, I cannot produce documentation for divorce or any other legal termination from my country. Now I want to apply for citizenship. Can I simply fill "terminated" or "annulled" in marital status section? This marriage, for all practical purposes, is dead.
