Is there ..

Is there a game on Steam where you play as ICE and get rid of the illegals?

Great concept for a game, but probably the closest would be that one mission in GTA5 I bets.

[Hammer Of Evil]

there used to be a mod on quake for this.

you'd play as one of three factions, border patrol, trespassers, and the smugglers.

that was really fun.

RON maybe, if you install mods i guess.

the FarCry series? lol you just gotta imagine you're playing as 'ICE'.
I'm certain that most or all of those bad guys are illegals ("undocumented trespassers").

I'm sure there will be an ICE simulator soon. There is one for almost everything else.

"Papers please" is about being migration agent.

You can try and be the opposite of an ICE agent and be the immigrant coming in with Super Trump 64

Papers Please springs to me.

I wish there could be more games about hackers. You having a morality system of deciding whether to be white, grey, or black. Always worrying if the cops have found you, or another hacker tried to frame you for refusing to do dirty work for them or enemy spies.

Reminds me of this one scene in GTA 5.

“Thought they deported you.”
“They can’t deport me. My family has been here for over 200 years. I’m more American than you. Not that that’s anything to boost about.”
