A statewide ballot measure, if approved, would give thousands of undocumented students access to in-state tuition.
Right now, non-citizens including young people brought to U.S. by their parents have to pay out-of-state tuition.
However, those so-called "Dreamers" believe they should pay the same as in-state students.
Proposition 308 allows dreamers who've lived in the state at least two years and graduated from an Arizona high school eligible for in-state college tuition.
"I've grown up here -- I went here to middle school, high school all throughout," said Emilio Ortiz, a sophomore at Arizona State.
He told ABC15 that out-of-state tuition costs nearly $30,000 a year at ASU.
That's about $20,000 more than in-state tuition.
According to the Immigration Higher Ed Portal, about 2,000 undocumented students graduate from Arizona high schools every year.
"For the majority of us...we don't know any place that isn't Arizona," said Ortiz. "We all grew up here and do the same thing as everyone else."
Ortiz said he receives scholarships to offset the cost of tuition.
Still, he thinks in-state would help others in his situation.
Ortiz said came to the U.S. with his mom from Mexico when he was 10 years old.
Organizers with Prop 308 said many students could benefit if the measure passes.
However, some Republicans disagree.
"If passed, this will lead to an increase in taxes statewide and would use our tax dollars to pay for illegal aliens and non-citizens to attend university at an equal or lower cost compared to American citizens," said Dr Kelli Ward, chairwoman of Republican Party of Arizona.
However, a study from the state budget office said it would not impact the general fund.
Supporters also argued by lowering tuition, more students could afford college and help the economy.
"Any person earning a college degree because of this policy would be about $28 million in net profit for the state as total spending power for that group of people," said Carlos Alfaro, Yes on 308's campaign manager.
Ortiz said he just wants to be treated the same as other people who grew up in Arizona.
"We're all just the same here, we're all Arizonans...please don't consider us as foreigners but just as your neighbors," he said.
On Friday, Grand Canyon University freshman Hazel Villatoro stood beside elected officials and businesspeople urging voters to support Proposition 308.Supporters, like Phoenix Mayor Kate Gallego and Mesa Mayor John Giles say offering dreamers the chance at an affordable college education will be a boost to the economy as much as it is a benefit for the students.
Giles is one of more than 30 Republican leaders who signed an open letter to Republicans calling on the passage of Proposition 308, saying the measure will cost taxpayers nothing while boosting the earnings of Arizona dreamers by more than $28 million annually.
"I mean you have a rule of law. They need to come in the right way and we need to fix our broken immigration system before we get to things like this," State Senator Michelle Ugenti-Rita, who opposes the measure said.
