What to Expect from the New Homeland Security Chief's Leadership

This week saw the confirmation of Markwayne Mullin as the new face of the Department of Homeland Security. While the department may have a new face, Mullen has vowed to continue the agency’s work with a business-as-usual attitude. Mullin was nominated to the position after the departure of Kristi Noem, whose tenure as DHS Secretary was marred by controversy, most notably the killing of two American citizens in Minneapolis.

At the same time, Mullin has suggested some potential shifts in how enforcement is carried out—such as greater respect for legal process and limits on certain aggressive tactics—though not a fundamental policy change. Notably, Mullin has signaled a potential change in the agency’s policy to require judicial warrants, in contrast to its previous widespread use of administrative warrants.

His appointment comes amid broader legal uncertainty, with major policies like asylum restrictions currently under judicial review, meaning that while DHS leadership matters, the courts will continue to play a central role in shaping immigration outcomes.

For immigrants and their families, this likely means that day-to-day enforcement will stay strict, with continued arrests and detention in many cases. At the same time, even small changes in how enforcement works—like requiring stronger legal approval before entering homes—could provide more protections in certain situations.

More broadly, the future of immigration policy will not be decided by DHS alone. Courts across the country are actively reviewing key policies, and their decisions could either strengthen or limit what the government can do. For now, the system remains in a period of change, where enforcement continues, but the rules are still being tested and defined.

We will continue to provide information and resources as the immigration landscape evolves.
