It doesn't work, because contrary to the myths of the right, most people in the country aren't here because they snuck over the border. The vast majority of "illegal" immigration is from people who come here on visas, and then just don't leave. Whether that's because they refuse to, or because they don't even know it's expired
(a common issue as well
), that's up for sociologists to study. Here's some studies on the topic if you want more info.

The whole outrage over "illegal" immigration is wholly manufactured. These people still pay taxes, put in their labor, and so on and so forth. I say just fuckin' naturalize em all. They contribute more to the country than people mad about brown people do.
