Even immigrants who came here legally say they're worried about what president Trump's wall will mean for them.
"I understand the suffering and I see it ever day," claims a somber Oscar Castaneda.
He immigrated to the United States for school.
"I didn't go through the pain that many people go through," Castaneda explains, "and those difficult situations, those difficult lives, I was pretty privileged."
And he doesn't think a wall will stop people from coming into the country legally.
"There are already huge spots of the US-Mexico border that already have a wall. And people keep coming!"
Supporters of the bill, like state representative Tom Barrett says that's exactly why the US needs to strengthen its borders.
"We're a nation of laws and that means there's a way to legally enter our country," states rep. Barrett (R)-Potterville, "and as Americans we get to decide who we welcome and who we don't. And I don't think we should see that right to any foreign entity or any person that decides to come here through illegal channels."
He says illegal immigrants cost taxpayers in Michigan and across the country, but Ruben Martinez says they help the economy, even up in Michigan.
"They're taking jobs that Americans don't want to do," Martinez says.
Those might be agricultural jobs in Michigan that people aren't working to begin with. And Castaneda says he believs that's part of what has made America great.
"This is a country made of immigrants. And immigrants made this country the beautiful country that it is today."
He hopes a wall won't change that.
