will over staying non immigrant visa 15 years ago be an issue for Naturalization

[Riddler21]

I came here with my parents on an A- visa diplomatic visa. which expired in 1995 aged 21. I stayed undocumented until I was married and later received a green card in 2004. Will the undocumented period be an issue in the interview? I should note that during the undocumented time, I was under 26 which brings the Selective service issue into play.

Is USCIS looking back before the greencard was received or will they ask about events prior to Permanent residency.
I have filed taxes for all years (even while undocumented, but working) and have not had any legal/criminal issues.

Thanks in advance

You will have no problem. Anything
Prior to the greencard is not important
But should be mentioned, to prove good
