Mark Zuckerberg and his wife are giving $5 million to a scholarship fund for undocumented immigrant students.
"America was founded as a nation of immigrants. We ought to welcome smart and hardworking young people from every nation, and to help everyone in our society achieve their full potential," he wrote. "If we help more young immigrants climb the ladder to new opportunities, then our country will make greater progress."
Zuckerberg is among Silicon Valley's most philanthropic people. In 2013, the Facebook CEO and his wife Priscilla Chan donated $1 billion, according to reports.
He came out as an advocate for immigration reform in 2013 when he spoke publicly for the first time on the issue.
"Someone did a study and it showed half of tech companies are founded by immigrants," he said. "These are issues that don’t just touch our industry, but really touch the whole country."
