President Trump has vowed to clamp down on immigration and undo Biden-era policies that he said were too permissive and blamed for allowing a large influx of undocumented immigrants. Here’s what we know about his policy changes.

Details of planned immigration raids are unclear, but they would be the opening step in the president-elect’s goal of overseeing the largest deportation program in history.

Immigrants in Chicago and other U.S. cities have been preparing for immigration arrests since President-elect Donald Trump won the November election.

Republicans in Springfield are calling on Pritzker to repeal the Trust Act, which bars Illinois law enforcement from engaging in immigration enforcement, but Chicago Deputy of Mayor of Immigrant, Migrant and Refugee Rights Beatriz Ponce De León said the city won’t bend when it comes to protecting the Chicago’s hardworking immigrant communities.

Chicago’s Little Village neighborhood, home to a large population of Latin American immigrants, has reportedly gone quiet, as the city waits to see whether it becomes the first target of Donald Trump’s plan to carry out mass deportations immediately upon taking office.

The incoming Trump administration is reportedly beginning mass deportations next week in the city and across the U.S., one of the president-elect's campaign promises.

The plans include phone trees, Know Your Rights flyers, role-playing ICE encounters and passports for children.

With more than 11 million undocumented immigrants in the U.S., Trump's Operation Aurora would cost billions of dollars.
