This guy doesn’t understand the issue. It isn’t whether a person born in another country to at least one US citizen parent is a citizen at birth. That’s a pretty cut and dried legal answer.
The questions are whether (1) his mother took any provable steps in Canada to drop her US citizenship, or (2) took any questionable steps in Canada regarding Ted’s or her own US citizenship.
“The questions are whether (1) his mother took any provable steps in Canada to drop her US citizenship...”
Hard to prove a negative. Do you have any evidence she did?
