Immigrants in the US, particularly in Chicago, are preparing for potential mass deportations following Donald Trump's election. Many are taking precautions, such as designating power of attorney and installing security cameras. Trump plans to target individuals with violent criminal histories, and his administration is expected to cast a wider net than Biden's. Immigrant rights advocates are urging calm and awareness of rights. Personal stories highlight the fears and contingency plans of immigrants like Carlos and Elena, who worry about separation from their children.
