While Congress discusses whether Deferred Action for Childhood Arrivals (DACA) - the program that protects immigrants who were brought to America as children - will remain in place, Bezos has donated millions to TheDream.us, an organization that helps immigrants get a college education.
The $33 million would pay some tuition and other expenses for 1,000 DACA students through a scholarship nonprofit, TheDream.US.
The donation from Bezos, who is the richest person in the world with an estimated net worth just shy of US$100 billion ($137.8b), will go towards funding 1,000 college scholarships, according to the Daily Mail.
Bezos said his adpoted father came to the U.S. from Cuba unable to speak English.
"With a lot of grit and determination - and the help of some remarkable organizations in DE - my dad became an outstanding citizen", said Bezos.
The donation "is a shot in the arm for Dreamer students at a time when some are questioning whether they should be in the United States at all", Candy Marshall, president of TheDream.US, told the Washington Post.
The organization now works with more than 70 low-priced colleges across 15 states.
The students will receive a total of $33,000 in scholarship aid over four years to cover tuition, fees and books at one of 70 colleges in 15 states.
Currently, "2,850 students are enrolled in college under the programme", the fund said in a statement on Friday.
The announcement comes at a time of uncertainty for DACA recipients, who are not eligible for federal financial aid, most state aid, and who often express uncertainty about their ability to afford college.
The program is less than four years old so there are no graduation rates yet. They must pay out-of-state or worldwide tuition in more than 15 states, the foundation said. As the son of an immigrant himself, Bezos says he's honored he's able to help. "I'm thinking I want much of my philanthropic activity to be helping people in the here and now - short term - at the intersection of urgent need and lasting impact", stated Bezos. The Bill and Melinda Gates Foundation, Pershing Square Foundation and Chan Zuckerberg Initiative are also among the other major contributors to the program.
