MOUNTAIN VIEW VOICE -- Jose Antonio Vargas is preparing to make his directorial debut. The Mountain View High School alumnus, former Voice intern and Pulitzer Prize-winning journalist will screen his new film, “Documented,” in Washington D.C., this week. Vargas — who famously “came out” in the pages of The New York Times Magazine, revealing his family brought him into the United States illegally when he was just 12 — has made his documentary debut, premiering June 20 as a part of the American Film Institute’s annual AFI Docs festival. Katherine Pantangco was among the very first to learn Vargas’ secret, in 2011. Before The New York Times Magazine ran his essay, “My Life as an Undocumented Immigrant,” Vargas visited the Mountain View High School student newspaper and told Pantangco — then a junior — and her classmates about his intention to publicly disclose his status. Now, with Pantangco attending Vargas’ alma mater, San Francisco State, she said she is excited to see the film.
