Today, President Obama dedicated "Nuestra Señora Reina de la Paz", national headquarters for César Chávez's United Farm Workers movement, a National Historic Landmark.

In his remarks President Obama said,

"César Chávez believed that when a child anywhere in America can dream beyond her circumstances and work to realize that dream, it makes all our futures just a little bit brighter."

"It was that vision, that belief in the power of opportunity that drove César every day of his life. It's a vision that says, maybe I never had a chance to get a good education, but I want my daughter to go to college. Maybe I started out working in the fields, but someday I'll own my own business. Maybe I have to make sacrifices, but those sacrifices are worth it if it means a better life for my family."

"That's the story of my ancestors; that's the story of your ancestors. It's the promise that has attracted generations of immigrants to our shores from every corner of the globe, sometimes at great risk, drawn by the idea that no matter who you are, or what you look like, or where you come from, this is the place where you can make it if you try."
