This seems really simple to me, although I admit to getting caught up in the eddy of blather from both sides.
DACA: Deport any "childhood arrival" who isn't fluent in English. Deport them if they have a criminal record or are on state assistance. Give them amnesty and legalize them if they're productive and have kept their nose clean. Anyone who doesn't want to become a US citizen, deport them.
"Dreamers": if they're not actively "dreaming", deport them. If they're going to college and not keeping up a reasonable GPA, back to their #### hole they go.
Chain migration: It's ridiculous that that's even a thing. Get rid of it because it's crazy. If immigrants want to be with their families so bad, stay your ass home and don't come here. Duh. If you're not a citizen you shouldn't be able to sponsor ####. That's like saying, "Okay, pal, you can come stay at my house for a year until you get on your feet," and he then invites all of his family members to come live in my house too. It's probably the most outrageous immigration thing I've ever heard of. So all gone with chain migration - no parents, no children, no siblings, no widowed aunties, no nobody.
The Wall: fund and build the ####ing thing, and enforce our immigration laws.
Sanctuary cities: Throw the Mayors of these cities in prison for breaking federal law. Not sure when we started letting the inmates run the asylum here.
And while we're at it:
Anchor babies: Be gone with that, too. That's almost as ridiculous as chain migration.
Anyone who disagrees with any of that is an unreasonable schmuck who should be disregarded as such.
