Entering the country illegally—without going through an immigration     checkpoint—or overstaying a visa isn’t a criminal offense but rather a     civil violation of federal law. A              growing percentage of the “undocumented” population in the U.S.          are people who overstayed their visas rather than people who made     unauthorized border crossings. Of the estimated 11 million undocumented     immigrants in the U.S. today, about 500,000 reside in Illinois,              mostly in the Chicagoland area.


         After processing, adults arrested in Illinois are then taken from the     processing centers to one of seven county jails in the region that hold     immigration detainees for ICE: to the Kankakee, McHenry, or Pulaski county     jails in Illinois, the Kenosha or Dodge county jails in Wisconsin, the Clay     County Jail in Indiana, or Boone County Jail in Kentucky. In all of these     facilities, immigration detainees are held in separate parts of the jail     from local arrestees charged with crimes. In 2012 the Pulaski county     jail (also known as the Tri-County Detention Center) was              named one of the ten worst          immigration detention facilities in the country by the Detention Watch     Network. Currently, the jails ICE uses in Illinois only have space for     about 1,400 ICE detainees, but with Trump’s promises to ramp up immigration     enforcement, ICE could soon be building or contracting with new facilities     in the region.



         The odds of winning a deportation case are slim. But they become impossible     if one waives one’s right to a hearing in front of a judge. West Suburban     Action Project’s Ruiz Velasco says that ICE agents frequently try to get     people to sign hearing waivers without explaining what they are, or by     promising that a person can fight their deportation from their home     country. But once signed, ICE takes the waivers to immigration judges who     then issue deportation orders. Often, people aren’t even aware that they’ve     signed away their right to fight their case or that they’ve been ordered to     leave, Ruiz Velasco says.



         Immigration experts say these orders are vague and leave too much to the     discretion of ICE officers.



         Usually, she says, ICE agents arrive in unmarked cars and wear Kevlar vests     with “police” written on the front. Their identification as ICE agents may     appear in small letters on the back of their uniforms. They also don’t     typically tell people they’re immigration agents, Ruiz Velasco says, so     people open the door assuming it’s the cops. There are no equivalent to     Miranda rights for immigration arrests, yet agents can use anything people     tell them against them in court.
