Dan-El Padilla Peralta's family arrived in New York legally from the Dominican Republic.
But their visas lapsed, and they stayed. Dan-El excelled in school, winning a private school scholarship and zooming to the top of his class.
It was just before his salutatorian speech at Princeton that Dan-El revealed to the world that he was "undocumented," a story he tells in his book, Undocumented: A Dominican Boy’s Odyssey from a Homeless Shelter to the Ivy League.
Dan-El joins us on the air to talk about that odyssey.
