It is not misrepresentation.Hi spyfy,
Sometimes, I use my last name spelled differently (the difference is in one letter). I use this another spelling is some semi-official circumstances, like when they ask you name but do not actually ask for the proof or at my website.
And I forgot to mention this another spelling in Q6. Unfortunately, it is easy to google - when you google my name, both spellings appear and it is obvious, that both refer to me.
Do you think this is a serious mistake? Is it "false representation"?
No one on here knows what is a serious mistake or not. The best thing after sending your citizenship application is to not think about it for a month. Thinking won't make it any better. Wait until you get AOR or until they send it back to you. There is literally nothing you can do until then, except go crazy over every single detail
