You can give up a birth right. If she chose to come back and regain her citizenship she could, but can never regain that Natural Born Status based on the simple fact that another Nation had claim to her. You can give up Natural Born Status.
“You can give up a birth right.”
No, you can’t You can choose not to assert it, but that’s another matter. Such rights are “inalienable,” meaning not transferable. It remains forever with the holder.
“If she chose to come back and regain her citizenship she could, but can never regain that Natural Born Status based on the simple fact that another Nation had claim to her.”
That makes no sense. Disclaiming citizenship does not alter her natural born status, which is set at birth and never changes.
“You can give up Natural Born Status.”
I wholeheartedly disagree. It is completely outside of your power to do anything about what your status was at birth.
