After years of promising fixes, the Department of Homeland Security again said only Congress can deliver real immigration reform—and the agency will stick to enforcing the law as written.
Story Snapshot
- DHS leaders across parties say only Congress can enact comprehensive immigration reform.
- Past secretaries paired calls for reform with “enforcement first” and tighter border control.
- DHS cites legal limits on detention and removal without new laws from Congress.
- Recent DHS statements emphasize enforcing the Immigration and Nationality Act as written.
DHS Frames Reform as a Job for Congress, Not the Department
Department of Homeland Security leaders have, for years, said comprehensive immigration reform requires Congress to act. In 2013, Secretary Janet Napolitano urged the Senate to pass a “firm, fair and effective” plan and pledged cooperation from the department. In 2024, Secretary Alejandro Mayorkas again called on Congress to pass bipartisan legislation to provide tools and resources the department lacks. These statements set a clear pattern: lawmakers must change the rules; the department must enforce them.
That division of labor echoes the Constitution. Congress writes immigration law, while the Department of Homeland Security carries it out. Secretaries from both parties have stuck to that view. They have supported targeted actions where possible. They have also warned that big shifts, like new legal categories or a path to legal status, need statutes. The message is steady even as politics change: without new laws, the department’s room to move stays narrow.
Enforcement-First Posture Anchors the Agency’s Approach
Homeland Security Secretaries have often tied reform talk to stronger enforcement. In 2007, Secretary Michael Chertoff told the Senate the department’s vision started with control of the border and robust interior enforcement, paired with limited legalization and worker programs. That model still shows up in public messaging today. It is popular with many who want order first, then a debate on status. It also shows why Congress is central: only lawmakers can update the system’s core parts.
Recent department statements under President Trump’s second term highlight strict enforcement of current law. In early 2025, the department said it would fully enforce the Immigration and Nationality Act and would not pick and choose which laws to enforce. That stance speaks to a broad concern on both right and left: people want a system that is clear, fair, and consistent. It also reflects the agency’s view that it must follow the text on the books until Congress changes it.
Legal Constraints Limit Unilateral Moves by DHS
Department leaders have also flagged legal barriers that only Congress can fix. In 2018, Secretary Kirstjen Nielsen said laws prevented the department from detaining families during prosecution and immigration cases, making it impossible to detain and remove whole family units as a matter of law without changes from Congress. That example shows the bind. Even aggressive policy goals can run into court rulings and settlement limits. Statutes, not memos, decide the outer edge of action.

Secretaries have also described how the department sets priorities inside those limits. In 2023, Secretary Mayorkas said guidance would focus limited resources on people who pose threats to national security, public safety, and border security, aligning operations with what Congress funds and authorizes. That is a triage model. It does not replace reform. It manages risk while the larger system stays the same. It also underscores why many Americans feel Washington avoids the hard fix.
Why This Matters for a Frustrated Public
Millions of Americans see a system that feels both harsh and chaotic. Conservatives see weak borders, crime risks, and costs. Liberals see family splits, legal limbo, and unequal treatment. Both sides blame Washington’s failure to deliver clear, lasting rules. The department’s message—that it will enforce the law and that Congress must reform it—tracks with that anger. It also highlights a deeper worry: powerful leaders talk reform, then pass the buck when it counts.
What is new today is not the argument. It is the stakes. The border is under strain, labor markets need certainty, and local communities carry costs of delay. The department says it will do its job under current law. That is necessary but not sufficient. Without congressional action, the cycle repeats: surge, crackdown, backlog, outrage. Voters who fear a government run by elites hear a familiar echo—lots of press releases, little durable change.
What to Watch Next
Watch whether congressional leaders put a real bill on the floor and allow a vote. Look for text that marries tighter border control with clear legal paths and faster decisions. Track whether the department gets new resources and authority to handle families, asylum, and workplace enforcement. Absent those steps, expect more targeted operations and court fights, not a reset. The agency will enforce the law it has. Only Congress can write the law the country needs.
