Yup - business owners who knowingly employ undocumented migrants should face severe penalties. The state should straight up seize their businesses and throw them in jail for at least a decade.

If a city doesn't cooperate with ICE then undocumented migrants are more likely to go there.

Having any sort of a visa policy means that we have to not let some people in.

But if you reward those who break the law to get in the country - it will just encourage more people to come.

Also why should someone try to migrate legally? Get all the paperwork sorted and everything. Just to see a bunch of undocumented immigrants skipping the line and getting in?

If I come to the USA as a tourist - why do I even have that 90 day time limit? Why can't you let me stay as long as I please?

The USA has so-called "sanctuary cities" that protect undocumented immigrants. Those cities encourage the immigrants to come, because it's less likely that they'll get punished for that.

Yup - immigrants who come to the country legally don't cause all those problems.

So what do you propose? To give legal permanent resident status to everyone who shows up at the border?

To abolish all visa policies and let everyone in?

Immigrants who are in the country illegally:

1. Don't pay all taxes.
2. Depress wages, because they are willing to work for less
3. Reduce housing supply for citizens and legal immigrants.
4. Mess up infrastructure planning, because they don't exist in government databases - so you plan for fewer people than you should.
5. Make police work harder, because again - they don't exist in official databases. And if they are witnesses or victims - they are less likely to report crimes.
6. They can have problems insuring their vehicles - so their victims could have problems getting paid in case of a crash.

And the positive side:

1. If you're a greedy capitalist who wants to exploit their workers by paying them less than a minimum wage, forcing them to work overtime, not offering paid vacations and health insurance and ignoring work safety laws - then undocumented immigrants are what you need.

They were deported, because they were in the country illegally and were ordered to leave 25 years ago.

They couldn't get citizenship during all those 35 years?
