No, she isn’t.
When she was either running or after the stolen election, I did some searching. Jamaican law, at the time she was born as as far I know has not changed, mandates that any child born to ONE Jamaican parent, anywhere in the world, is at birth a Jamaican citizen. She was born in the US to two foreigner parents, father Jamaican, mother Indian, both here on student visas. Which according to actual law, would not render her a US citizen at all. But since now one gives a crap about that any more, the Jamaican law makes her a dual citizen.
