The difference between in-state and out-of-state tuition for students is huge, so the ruling will save the students thousands of dollars.
It doesn't apply to Arizona's universities, but dreamers attending community college can get in-state tuition.
"When I heard the news I was so happy I started crying, this means the difference between finishing, and not finishing my education," said Belen Sisa.
Sisa's dreams are now within reach. She was brought here to Argentina when she was 6-years-old, went to public school, and now attends community college. Eventually, she wants to go to law school.
"This is our home, you have invested in us for the past 12 years, this is our chance to give back to Arizona, to give that investment back," she said.
The decision was handed down by Arizona Superior Court Judge Arthur Anderson and only allies to Maricopa County Community Colleges. The ruling is in response to a lawsuit filed by the Arizona Attorney General's Office that would've forced dreamers to pay the higher fees.
"Paying in-state, it's the reason I'm here, it gives me that sense of I can do it, I can afford my school... I'm just a very happy person looking to better myself," said Cesar Calderon.
Out of state tuition at many community colleges is triple the in-state tuition rate. Dreamers attending Arizona's universities will still pay more.
The Arizona Board of Regents is considering a proposal that would have dreamers paying 150% of in-state tuition costs.
"We're not asking for help to pay for school, we're asking for an equal chance to pay the same as everyone else," said Sisa.
Current Arizona Attorney General Mark Brnovich issued the following statement: "No one is more sympathetic to the cause of immigration than Attorney General Brnovich, but the law is the law. Attorney General Brnovich believes he has an obligation to respect the will of Arizona voters. Our office is currently reviewing the decision and weighing all legal options including appeal."
