I've mentioned this before and even cited reference to it and was shouted down. There are few things in life that have absolutely no defense. Even murderers have some sort of defense. Claiming US citizenship however is an unforgivable sin under the law so do not under any circumstance readily offer up documents that has shown you did this whether it's a job application or tax form. At least talk to a lawyer about it because obviously I'm not one...neither are you.
