Step One: send back anyone with a crime history.
In a giant slingshot.
“Step One: send back anyone with a crime history.”
That’s what I would do. If you are an illegal and spent time in a US prison or have a felony on your record, you and your entire family will be sent back to country of origin. Once there, when your scheduled parole ends, and you haven’t been convicted of a crime in your own country, you and your family can apply for citizenship.
That’s actually the fairest way to do this.
