Illegal immigratiion goes down if the immigrants can't find work when they arrive in the USA. Obama got orders against 450 employers in just his last YEAR in office. THAT's why 2017 had the lowest rate of illegal border crossings in the past 50 years. 300,000 Mexicans self-deported when Obama was in office.
Donald Trump cancelled all of the enforcement orders and only prosecuted 1 employer in his entire 4 years in office. All those Republican donors put out the "Now Hiring" signs south of the border, and they made a run for the jobs, driving up illegal crossings to the point where Trump had to declare a National Emgergency at the Southern Border.
You encourage tourism from around the world. You give student visas to anyone who has the money for tuition. MOST of you illegal immigration is people who come in on visas and never leave, but you just go crazy over people seeking asylum from war, violence and famine, which your government's polices caused in the first place.
It's pointless. You're too stupid to do anything but bleat the lies like a good little Republican.
