💡 IN SHORT

The Department of Labor's Project Firewall has driven a 48% surge in H-1B investigations and assessed over $15 million in back wages, using AI and Palantir-linked analytics to scan thousands of filings at once. Immigration law firms that rely on email folders and scattered spreadsheets are now dangerously exposed — matters must live in one system with linked documents, timelines, and financial records.

⚖️ What Project Firewall Actually Changed

Project Firewall, launched in September 2025 by the U.S. Department of Labor, shifted H-1B enforcement from complaint-based to proactive, AI-driven investigation. Every certified Labor Condition Application (LCA) and H-1B filing is now subject to pattern analysis across DOL, USCIS, DOJ, and EEOC datasets. By late 2025 roughly 200 investigations were active, and the DOL has reported a 48% jump in probes.

🚫 Red Flag

Investigations target wage violations, nonexistent work sites, misrepresented job duties, failures to notify USCIS of terminations, and "benching" unassigned workers. A single mismatched address or stale LCA posting can trigger a federal audit.

🔍 What the DOL Is Actually Looking At

Investigators are cross-checking eight categories against three years of records. Firms that cannot produce a clean, linked chain of evidence face back-wage orders, six-figure civil penalties, and in serious cases debarment from the H-1B program.

📍

Worksite Addresses

Every LCA address must match the actual place of employment — including remote work and short-term placements.

💵

Wage Payments

Actual payroll must meet or exceed the required wage on every pay period, with evidence of benching avoidance.

📋

Public Access Files

PAF must be ready within one business day of request and contain all required notices and wage documents.

🛑

Termination Notices

USCIS must be notified of H-1B terminations; failure to do so is a common Project Firewall finding.

🧾 Why Scattered Records Are the Real Problem

Most immigration firms do not fail audits because of bad lawyering. They fail because the evidence lives across email threads, a shared drive, a QuickBooks ledger, and a sticky note on a paralegal's monitor. When the DOL sends a request, firms have days — not weeks — to produce a complete record.

⚠️ Watch Out

The DOL uses interagency data matching. If your LCA addresses do not match the employer's own payroll tax filings, the system will flag it before any human reviews the file.

🧠 How CaseQube Makes Matters Audit-Ready by Default

CaseQube was designed for the exact scenario Project Firewall creates: every document, deadline, communication, fee, and disbursement tied to a single matter record. When the DOL asks, the answer takes minutes, not days.

📁

Matter-Linked Documents

CloudDoc auto-classifies every file — LCA, PAF, I-129, wage evidence — to the correct matter with audit trails.

⏱️

Deadline Automation

Termination notice deadlines, LCA validity periods, and PAF posting rules trigger alerts automatically.

💼

Client & Employer Profiles

Beneficiary, petitioner, and worksite records stay consistent across every filing — no address drift.

📊

Financial Audit Trail

LawAccounting ties filing fees, prevailing wage surveys, and disbursements directly to the matter.

💡 Pro Tip

Run a "Project Firewall dry run" once per quarter. Pick three random active H-1B matters and try to produce the full PAF, LCA, wage records, and termination logs in 24 hours. If any piece lives outside your case system, that is your audit risk.

🛡️ Five Steps Immigration Firms Should Take This Month

Preparing for Project Firewall is not about a single feature — it is about operational discipline. Every firm handling H-1B, L-1, or E-2 work should walk through this sequence now, not after a subpoena arrives.

✅ Key Takeaways

Project Firewall uses AI and Palantir-linked analytics to scan H-1B filings across agencies — audit triggers are automated, not complaint-driven.
The DOL reported a 48% jump in investigations and $15M+ in assessed back wages within the first year of the program.
Most audit failures come from scattered records, not bad lawyering — email, shared drives, and QuickBooks cannot produce a unified chain of evidence.
CaseQube links every document, deadline, and dollar to the matter, turning a multi-day records pull into a one-click export.
Quarterly "audit dry runs" on random matters are the single highest-leverage practice immigration firms can adopt in 2026.
