(UNITED STATES) — Homeland Security Secretary Markwayne Mullin announced that Todd Lyons, the acting director of U.S. Immigration and Customs Enforcement, will leave the agency on May 31, 2026, after Lyons submitted his resignation on April 16, 2026.

Mullin said Lyons is moving to the private sector and called him “a great leader of ICE” who “jumpstarted an agency that had not been allowed to do its job for years.” Lyons has served as Acting ICE Director since March 9, 2025.

No permanent successor had been named in the reports. The departure leaves a leadership question at the agency carrying out arrests, detention and removals as President Donald Trump presses an expanded immigration enforcement campaign.

Lyons is a 20-year ICE veteran who began as an immigration enforcement agent in Texas and later led the agency’s Boston office. His tenure at the top coincided with a broader enforcement push that included larger arrest operations, detention growth and more aggressive interior actions.

White House spokesperson Abigail Jackson defended Lyons publicly, calling him “an American” on X. Administration allies also backed his record as ICE remained central to Trump’s deportation agenda.

His exit follows a period of heavy scrutiny over ICE tactics. Rights groups criticized enforcement actions in Minneapolis and other cities, while court scrutiny in Minnesota focused on allegations that the agency had not complied with judicial directives in multiple cases.

That pressure grew as ICE expanded its reach. Lyons drew attention for approving a memo that gave federal immigration officers broad authority to enter homes and make arrests without a judge’s warrant in certain circumstances.

The legal distinction remains central to many immigration cases. An administrative warrant is not the same as a judicial warrant, and forced entry into a home raises separate Fourth Amendment questions that often appear in suppression motions, habeas petitions and civil-rights suits.

Lyons’ departure does not by itself alter those enforcement powers or suspend removals. ICE authority runs through the agency and the Department of Homeland Security structure, not through any single official, and a leadership change alone does not rewrite immigration law or cancel existing directives.

Immigrants with active ICE check-ins, ankle-monitor requirements or final removal orders are likely to see those obligations continue unless they receive new official notice. Families in removal proceedings and people with unresolved immigration cases face uncertainty over style and priorities, not a pause in enforcement.

Employers should expect the same posture in the near term. A new leader can influence worksite investigations, I-9 audits, detention decisions and coordination between enforcement components, but high compliance expectations remain in place unless DHS announces a policy shift.

The distinction between ICE and U.S. Citizenship and Immigration Services also remains unchanged. ICE handles interior arrests, detention and removals, while USCIS decides benefits such as green cards, work permits and naturalization, so a leadership change at ICE does not directly change visa adjudication rules or USCIS processing guidance.

Students, temporary workers, green card applicants and visitors are less directly affected by who runs ICE than by border policy, visa rules and USCIS procedures. People with prior status violations, criminal exposure or unresolved removal matters remain more exposed to continued enforcement activity.

What changes next depends on who replaces Lyons and whether DHS makes that person a permanent appointee. A hard-line acting chief would point to continuity, while a successor with different legal instincts could shift detention decisions, prosecutorial discretion, field-office conduct and the agency’s response to judicial pushback.

Several accounts of Lyons’ departure offered different reasons, including family time with his sons in Massachusetts, a move to the private sector and health struggles that included multiple stress-related hospitalizations. Mullin’s public statement pointed to the private sector.

For now, the enforcement system Lyons helped oversee remains in place. DHS has announced his departure date, but the immediate picture is continuity inside ICE, with the next test resting on the choice of successor and any new guidance or court limits that follow.
