No, it isn’t. For example, BO signed the application to get his name printed on the AZ Presidential preference primary explicitly swearing, in writing, he is a NBC. This in part was why seeing those words “native” on his then new FTS web site, jumped out at me.
You are correct. I can’t remember everything.
Of course, your observation would have had more impact had you included a copy of the document you reference.

When Obama signed that document he committed perjury, also known as forswearing. It is the willful act of swearing a false oath or affirmation to tell the truth, whether spoken or in writing.
Perjury is considered a serious offense, as it can be used to usurp the power of the courts, resulting in miscarriages of justice. In the United States, for example, the general perjury statute under Federal law defines perjury as a felony and provides for a prison sentence of up to five years.
