What purpose does the department of immigration serve?
I’ve done the legal paperwork for two women to get into the United States. It was fucking brutal. It was like having a second job. I did it because they were in love with American men, and very much wanted to live the dream. They had to undergo a medical test to make sure they weren't bringing a disease into the country.

They had to undergo a background check, to make sure they weren’t criminals.

So now, Jo Jo the clown is letting in 500 thousand illegals per month. What the fuck? I feel like a schmuck.

Now I just tell my international friends to enter the country illegally. Just fly to Mexico, and wade across the river. Just promise to vote Dimocrat, and laws no longer matter. I challenge you to prove me wrong.
