All these news today about immigrant fear, especially when Trump takes over, is really officiated by the 9/11 attack in 2001. Sure, there's always extreme right (racists, anti-immigrant, Yankees who prefer to see the black slaves returned to Africa, etc.) vs. left wing on this issue, but they could never really do much by law until the terrorist attack.
Here's some basic info:
After 9/11, Homeland Security (DHS) was formed. Under which, we have U.S. Immigration and Customs Enforcement (ICE), Customs and Border Protection (CPB), and U.S. Immigration and Customs Enforcement (USCIS).
To work for ICE, you must be U.S. citizen, 21-37, priority goes to those with degrees related to criminal justice.
The enforcement is distinguished into two categories: civil (i.e. folks with overstayed visas, etc.) and criminal offenses.
With Google AI help: The two primary enforcement components of U.S. Immigration and Customs Enforcement (ICE) are Homeland Security Investigations (HSI), which targets transnational crime, and Enforcement and Removal Operations (ERO), responsible for apprehending, detaining, and removing immigrants, focusing on public safety and immigration law violations within the U.S.. HSI investigates smuggling, trafficking, and financial crimes, while ERO handles deportations and detention, often working with local law enforcement through programs like 287(g) to identify removable individuals.
