Status as a natural-born citizen of the United States is one of the eligibility requirements established in the United States Constitution for election to the office of President or Vice President. This requirement was intended to protect the nation from foreign influence.
My mother, Marian Pierce, was a naturalized citizen, having taken her test after graduating from Hillsborough High School in Tampa, Florida in 1933.
She would study and teach classes on the U.S. Constitution the rest of her 95 years.
Glad to see you back in Tampa hope to see you soon and before you move to Portland best wishes!
