There are documented cases of people being denied entry and subjected to expedited removal as this may be construed as misrepresenting oneself as a US citizen.
I remember one older Chinese lady who did this at JFK- but I think she didn't read English (and JFK, last I was there, had NO signange in any other languages in Immigration) and was just quite lost, so I hope they didn't deport her. They spent a lot of time trying to figure out her situation. Must have annoyed the people behind her.
