MINEOLA, N.Y. (AP) – An official from China who came to Long Island to learn about local government has discovered a $282.6 million error in a Nassau County budget document.

Ellie Su, 27, a supervisor in the government procurement division for Dongguan, in southern China, noticed that a debt service document entry read $31.4 million instead of $314 million.

Nassau County is getting Su’s expertise for free. Her government is paying her salary while she interns with the Office of Legislative Budget Review.

Su, who got her master’s degree from Saint Mary’s College of California, also might want to consider a career as a diplomat. After her discovery, she replied: “Still, I was surprised at how few errors I saw in such a big budget book.”
