The Trump administration’s latest immigration policies are already causing waves of anxiety among undocumented immigrants and advocacy groups. With sweeping changes aimed at tightening border security and speeding up deportations, many are left wondering what comes next.

One of the first moves was the cancellation of asylum appointments through the CBPOne app, a tool that migrants used to schedule interviews with immigration authorities. Now, thousands like Nedi, a Venezuelan mother of two who recently arrived in San Diego, are left in limbo. “We’re worried about not being able to stay, about being sent back,” she shared with reporters.

Trump has been vocal about his plans to reverse what he calls “permissive” Biden-era policies. On his first day back in office, he signed executive orders expanding ICE’s enforcement powers, including the ability to conduct raids in sensitive areas like schools and churches. Additionally, the administration is broadening the use of expedited removal, allowing authorities to deport individuals without a court hearing if they can’t prove they’ve lived in the U.S. continuously for at least two years.

These changes could lead to a significant increase in detentions. For example, Catholic Charities of San Diego, which has been sheltering migrants, was abruptly informed by CBP that they would no longer release migrants into their care. “They’re all panicking. They’re very fearful,” said the organization’s CEO.

Advocates, like Danielle Cosmes of the American Friends Service Committee, worry about the human cost of these policies. “What I can anticipate for sure is fear and uncertainty,” she said, warning that more migrants might attempt dangerous crossings, risking injury or worse.

Meanwhile, communities across the U.S. are preparing for potential ICE raids. In Chicago, teachers are undergoing training to protect their students, and local police departments have stated they won’t assist in immigration enforcement based solely on immigration status.

As these policies take shape, one thing is clear: the uncertainty and fear they’ve sparked aren’t going away anytime soon. For many, the fight to stay in the U.S. has just gotten tougher.
