With an executive order last month and a pair of Department of Homeland Security memos on Tuesday, the Trump administration has significantly hardened the country’s policies regarding illegal immigration. Here are some of the most significant elements of the new approach:

Who will be deported

In 2014, the Obama administration issued guidelines for deporting unauthorized immigrants that placed the highest priority on gang members, felons and those who posed security threats. A goal was to concentrate limited resources on the most serious cases, but many Immigration and Customs Enforcement agents complained that the priorities tied their hands, taking away their discretion as to whom to pursue.

Under the new directives, the government “no longer will exempt classes or categories of removable aliens from potential enforcement.” Immigration agents can now focus on picking up and removing anyone charged with or convicted of any criminal offense, even minor ones, as well as anyone already ordered deported, regardless of whether they have a criminal record.

One unauthorized immigrant in California, Kristina, who did not want her last name used because of fear of deportation, said she was alarmed to learn on Tuesday that she would now be considered a prime target. Kristina has been in the country for 25 years and has been ordered deported, but her removal had been postponed for the last four years by the Obama administration. “We have our whole lives here; our children are citizens,” she said. “Now I don’t know if I can go out, if I should drive.”
