Why?
As a person who has applied to places where a fairly detailed background was required, I had to develop paperwork to cover the important issues.
If you don’t have a birth certificate from the United States, you need to have other documentation that makes it clear you are a citizen.
During her career, she had to have undergone some background checks.
What did she use to get her driver’s license? What did she use to get her Social Security number? What did she use to get her marriage license?
How do you get to the place this woman was, without any documentation to verify she was a U. S. citizen?
It didn’t occur to her that she didn’t have the documentation? Seriously? I have a very hard time believing that.
