A DHS shutdown of the Department of Homeland Security (DHS) can sound, at first, like a system coming to a halt. It isn’t.

The machinery of U.S. immigration does not stop. But it does begin to move differently, less evenly, less predictably. Some parts continue to function as designed. Others slow, or go quiet altogether. What emerges is not a shutdown in the literal sense, but a system that is no longer aligned with itself.

In order to really grasp the effect, it is useful to trace the sequence of events. The recent DHS shutdown started on February 14, 2026, because a temporary funding measure lapsed without a new agreement being reached. Prior to this, Congress had passed a short-term extension funding DHS through a mid-February deadline, following an earlier brief shutdown in late January and early February.

Most immigration functions operated normally during the first two weeks of the shutdown. But as the shutdown stretched beyond 40 days, it created operational challenges that impacted both staffing levels and project schedules and coordination between agencies.

A System That Doesn’t Shut Down All at Once

A single pipeline does not control immigration in the United States. It is a network of agencies, each with its own funding structure, its own mandates, and its own constraints.

When a shutdown begins:

• Fee-funded operations largely continue
• Essential services remain in place
• Programs dependent on congressional appropriations may pause

The result is uneven. And for applicants, that unevenness is where uncertainty begins, especially across DHS immigration processes that rely on multiple agencies.

USCIS Operations During a DHS Shutdown

The U.S. Citizenship and Immigration Services (USCIS) continues to operate during a shutdown. Its funding comes primarily from application fees. Petitions are filed. Appointments are scheduled. Decisions are issued.

On the surface, little appears to change. But immigration cases rarely move through a single agency. They rely on a chain of approvals, each connected to another office, another process.

When those links weaken, even a functioning agency begins to slow.

So while USCIS continues its work, the pace and predictability of that work can shift, sometimes subtly, sometimes not. This is where visa processing timelines begin to stretch.

Where Delays Become Visible: Immigration Courts

In the immigration courts, the impact is more immediate. These courts fall under the Executive Office for Immigration Review (EOIR). Their operations depend more directly on federal funding.

During a shutdown:

• Hearings for non-detained individuals are often postponed
• Only limited categories of cases proceed
• Backlogs, already substantial, grow larger

For those waiting on a hearing, the delay is not abstract. It is time added to a process that is already measured in months, sometimes years.

The Quiet Bottleneck: The Department of Labor

Some of the most significant disruptions happen out of view. The U.S. Department of Labor (DOL) plays a central role in employment-based immigration. Its certifications are often a prerequisite for visa petitions.

During a shutdown, many of these functions stop:

• Labor Condition Applications are not processed
• Prevailing wage determinations are delayed
• PERM certifications do not move forward

Without these steps, entire categories of immigration filings stall, not because they have been denied, but because they cannot yet be completed.

It is a pause that can ripple outward, affecting visa processing timelines long after the shutdown ends. This is one of the less visible effects of a DHS shutdown.

Employers, Without Their Usual Tools

For employers, the obligations remain. The systems, at times, do not.

The E-Verify system program is typically unavailable during a shutdown. Employers must continue to verify work authorization, but they do so without the digital infrastructure they usually rely on. The requirement does not change. Only the method does. And for many, that shift introduces a degree of operational uncertainty across DHS immigration compliance processes.

Enforcement Does Not Pause

While some parts of the system are slow, others continue without interruption.

The U.S. Immigration and Customs Enforcement (ICE) maintains enforcement operations. The U.S. Customs and Border Protection (CBP) continues to manage the border. Detentions proceed, removals are still happening, and inspections continue.

These functions are considered essential. Their continuity underscores a broader truth: even in a shutdown, DHS immigration enforcement remains active.

Visa Processing: Dependent on Time

Visa processing, overseen by the U.S. Department of State, often continues at the outset of a shutdown. But this stability can be temporary.

As time passes:

• Staffing levels may be affected
• Appointment availability can narrow
• Visa processing times may extend

The longer the shutdown persists, the more visible the strain becomes.

A System Out of Alignment

The most accurate way to understand a shutdown is not as a stop, but as a misalignment. One agency continues to process applications. Another pauses entirely. A third operates at reduced capacity.

For applicants, this creates a process that still moves, but without coordination. A petition may be ready for review, but waiting on a certification that has not yet been issued. A hearing may be scheduled, then postponed without a clear timeline for resumption.

These are not failures of the system. They are consequences of its structure, often intensified during a DHS shutdown.

What This Means for Applicants and Employers

In practical terms, a shutdown introduces uncertainty into timelines that are already complex. Applications are not necessarily at risk. However, schedules are.

For those navigating the system:

• It becomes important to understand which agencies are involved in a case
• To anticipate where delays are most likely to occur
• To prepare for changes that may not be immediately communicated

The challenge is not always visible at the outset. It often emerges gradually, as dependencies surface.

A Final Word

A shutdown does not end immigration processing. But it reshapes it. It reveals how interdependent the system is, how much each step relies on another, and how quickly timelines can shift when even one part is paused.

For those within the system, the question is not whether their case will continue. It is how, and at what pace.
