What is Immigration Due Diligence?
Immigration Due Diligence is a structured review of a target company’s use of visa holders, sponsorship status, and immigration compliance framework as part of a broader Mergers and Acquisitions (M&A) or investment process.
It provides visibility over immigration-related risks that may not be immediately apparent in financial or operational reviews, but can materially impact valuation, integration, and post-acquisition exposure.
Where a business employs overseas workers, immigration compliance is a critical risk category that should be assessed alongside financial, legal, and commercial factors.
Why It Matters in M&A
Immigration risk does not disappear on acquisition.
In many cases, liabilities transfer with the business, including:
- Non-compliance with sponsorship obligations
- Employees working in breach of visa conditions
- Invalid or expired visas
- Incorrect nomination or occupation classifications
- Gaps in internal compliance processes
These issues can result in:
- Regulatory investigation or sanctions
- Loss of sponsorship approval
- Operational disruption due to workforce ineligibility
- Reputational damage
Identifying these risks early allows them to be managed, priced, or mitigated before completion.
What We Assess
Workforce Visa Review
We audit the target company’s workforce to determine:
- Which employees are visa holders
- Whether visas are valid and appropriate for their roles
- Whether visa conditions are being complied with
This provides a clear picture of workforce dependency on migration.
Sponsorship Status and Compliance
We assess whether the business:
- Holds valid sponsorship approval
- Is meeting ongoing sponsorship obligations
- Has any history of monitoring, warnings, or enforcement action
Policy and Process Review
We evaluate internal systems, including:
- Right-to-work checks
- Visa tracking and expiry monitoring
- Onboarding processes for overseas workers
- Internal governance and accountability
This identifies whether compliance is systematic or ad hoc.
Risk Identification
We provide a structured assessment of:
- Existing compliance gaps
- Potential regulatory exposure
- Areas requiring immediate remediation
Key Risk Areas in Transactions
- Reliance on visa holders in critical roles without compliance assurance
- Improper use of visa pathways (for example, using training visas as employment solutions)
- Missing or inadequate documentation for sponsored employees
- Unreported changes in employment conditions
- Lack of internal ownership of immigration compliance
These risks are often invisible without targeted immigration review.
Why These Risks Are Often Missed
Two patterns tend to sit behind the risks above:
A review is only a snapshot. Immigration compliance can be assessed as sound at a point in time, but if nobody is tracking what changes afterward, a role changing, duties shifting, a sponsorship arrangement being varied, a compliant position can quietly become non-compliant with no one noticing until it surfaces as a problem.
Immigration sits outside the usual conversation. Commercial decision-makers, finance, and legal don’t always know when a decision they’re making has an immigration consequence — and the person internally responsible for immigration (typically HR, People & Culture, or Global Mobility) isn’t always told about commercial developments early enough to flag it. Immigration ends up being the last function looped in, and issues are managed after the fact rather than being caught before they happen.
Commercial Impact
Immigration findings can influence:
- Valuation and deal pricing
- Conditions precedent or post-completion obligations
- Warranty and indemnity provisions
- Integration planning and workforce continuity
In some cases, immigration issues can delay or derail a transaction if not identified early.
Post-Acquisition Considerations
Following acquisition, sponsors must ensure continuity of compliance.
This may involve:
- Transferring or updating sponsorship arrangements
- Rectifying historical compliance issues
- Implementing new policies and monitoring systems
- Managing communication with the Department of Home Affairs
A clear understanding of the starting position is critical.
