Number of immigrants has been slowly increasing or steady for decades. It's a fantasy that it's a crisis or that there is a risk of tens of millions flooding our shores. We mostly drastically benefit from products downstream from cheap labor while tacitly allowing those who don't get in trouble so we can continue to benefit from this.

We could have "solved" immigration decades ago with enough punative treatment of employers but didn't want to.

If you want to actually stop it you could just ramp up punative treatment of employers over the next 5 years while keeping other policies at Obama or Bush era.

Half the undocumented without us family members would self deport gradually whilst jobs dried up. Offer amnesty to productive people with family roots and no criminal record and you end up with a microscopic undocumented pop.

Meanwhile DSHS is tweeting a pic of an island paradise with the caption America after 100M deportations. There are around 12M undocumented but about 100M non-whites if you have trouble interpreting their meaning or intention.
