Cross-Border M&A Immigration Due Diligence

Immigration rules have become a form of digital border control: detailed, data-led and increasingly difficult to navigate without understanding how each part connects. Employer sponsorship, ownership, job duties, salary, work location and reporting obligations sit together like a Rubik’s cube. Move one element, and the legal position may change elsewhere.

That complexity becomes especially acute during acquisitions, business transfers and carve-outs. A transaction may change the employing entity, break a qualifying corporate relationship, move employees into new roles or locations, or place them under a sponsor that does not yet exist.

At the same time, immigration rules may be changing in flight, with new reporting duties, tighter enforcement and narrower routes introduced while the deal is still progressing.

The result is a risk that can remain hidden until the workforce transition is already under way. By then, new applications may be required, key employees may face interruptions to work authorisation and the buyer may have fewer options than it expected.

For cross-border M&A, immigration therefore needs to be thought through well before closing: not as a final compliance check, but as part of the workforce transition itself.

Closing an M&A Deal Does Not Guarantee Immigration Continuity

In a cross-border transaction, employment continuity and immigration continuity do not necessarily move together.

An employee may transfer under local employment law, retain their contract and remain essential to the acquired business, while the immigration permission supporting their role no longer fits the new arrangement. The permit may name a specific employer, depend on a corporate relationship, restrict the approved role or salary, or tie the employee to a particular work location.

This creates a distinct risk during acquisitions, mergers and carve-outs. The workforce may transfer on paper, but sponsored employees may still require:

• a new work permit or sponsorship application;
• notification of a change in employer or ownership;
• an amended filing for a new role, salary or location;
• confirmation that the acquiring company qualifies as a successor;
• a temporary employment route while the buyer completes its local setup.

The position can differ even among employees working in the same country. One permit may continue after a notification, another may require approval before the employee can work for the buyer, and a third may cease to qualify because the transaction changes the ownership relationship behind it.

The first immigration review should therefore identify where legal employment can continue but work authorisation may not. That gap is where critical roles, closing timelines and post-deal integration plans are most exposed.

How the M&A Transaction Type Affects Employee Work Permits

The immigration outcome often depends less on the employee’s visa category than on what the transaction changes around it.

A share acquisition, statutory merger and asset purchase may all transfer control of a business, but they do not affect the employing entity in the same way. That distinction can determine whether existing sponsorship remains valid, whether the buyer can rely on successor provisions or whether new applications are required before employees can continue working.

Share acquisition

In a share purchase, the target company usually remains the same legal employer. Its registrations, sponsor records and existing immigration filings may therefore remain in place.

However, continuity should not be assumed. A change in direct or ultimate ownership may trigger reporting duties, fresh sponsor checks or a new licence application in some jurisdictions. The buyer also inherits any existing compliance failures, including incorrect work locations, unreported role changes or incomplete right-to-work records.

Merger or corporate reorganisation

A merger may allow the surviving entity to step into the immigration position of the predecessor, but successor treatment varies by country and permit type.

Authorities may look at whether the employment terms remain materially unchanged, whether the surviving company accepts the predecessor’s obligations and whether the required notifications are made on time. Changes to salary, duties, title or location can still trigger amended filings even where the corporate succession itself is recognised.

Asset purchase or carve-out

Asset purchases and carve-outs usually create the greatest immigration friction because employees move to a different legal employer.

Existing sponsorship may not transfer automatically. The buyer may need new permits, registrations or approvals, while employees remain with the seller, move under a temporary employment arrangement or wait before they can begin work for the acquiring company.

This is where immigration can directly affect the closing timetable. A transaction may be legally complete while part of the workforce is still unable to move with it.

M&A Immigration Due Diligence: Seven Questions to Resolve Before Closing

A country-by-country review should identify where the transaction changes the basis on which employees are allowed to work. The most useful starting point is not a list of visa categories, but a clear picture of the affected workforce and the changes each employee will experience.

1. Which employees depend on employer-sponsored immigration status? The review should cover permanent employees, executives, intracompany transferees, graduate workers, secondees and any dependants whose status is linked to the principal applicant.
2. Which legal entity currently sponsors each employee? Group charts and HR records do not always show the entity named in the immigration filing. The sponsor, employing entity, payroll entity and day-to-day business may not be the same.
3. Will the sponsoring entity survive the transaction? A share purchase may preserve the employer. An asset purchase, carve-out or internal reorganisation may replace it. That distinction can determine whether existing permission continues or new sponsorship is required.
4. Does the country recognise succession or permit transfer? Some jurisdictions allow the new or surviving employer to assume existing immigration obligations. Others require notification, a new sponsor registration or a fresh application before the employee can work under the new arrangement.
5. Will the employee’s role, salary or work location change? A new title, reporting line, salary, occupation code, client assignment or worksite may trigger an amendment even where the legal employer remains unchanged.
6. Are the current immigration records compliant? Due diligence may uncover expired documents, unreported changes, incorrect work locations, missing right-to-work records or employees working outside the conditions originally approved.
7. Can every affected employee continue working without interruption after closing? The answer should be established before the closing timetable and workforce transfer plan are finalised. Where approval cannot be secured in time, the deal team may need a delayed transfer, interim employment route or revised integration plan.

Employee Groups to Include in M&A Immigration Due Diligence

Immigration reviews often focus first on senior leaders and high-profile transferees. The wider exposure usually sits across a more varied employee population.

1. Intracompany transferees
   Their status may depend on a qualifying relationship between the overseas and local group companies. A merger, divestment or carve-out can alter that relationship and remove the basis for the assignment.
2. Technical specialists and project-critical employees
   These employees may hold employer-specific permits tied to a defined role, salary, client site or location. Integration changes can therefore trigger fresh filings even where the individual remains in broadly the same position.
3. Graduate and post-study workers
   Graduate routes may depend on employer registration, training plans or ongoing reporting. Changes to the employer, payroll entity or corporate ownership can create new compliance steps.
4. Employees awaiting permanent residence
   A pending residence application may rely on continued sponsorship, an approved role or a particular employer. Workforce transfers, salary changes or redundancies can affect the application before permanent status is secured.
5. Dependants
   A transaction can affect spouses and children whose immigration status is linked to the principal employee. Their position should be reviewed alongside the sponsored worker, particularly where new applications or travel restrictions may apply.
6. Remote and hybrid workers
   The immigration record may show one approved location while the employee works from another region, home address or client site. M&A due diligence can expose these existing discrepancies at the same time as the transaction creates further changes.
7. Secondees and employees working across group companies
   The company directing the work may differ from the legal employer or sponsor. A corporate reorganisation can expose arrangements that were already unclear or no longer reflect the approved assignment.
8. Employees selected for post-closing redundancy
   Termination may trigger sponsor notifications, permit withdrawal, residence implications and, in some countries, repatriation obligations. These consequences need to be assessed before the redundancy programme begins.

How Immigration Rules Differ Across Global M&A Transactions

The same transaction can produce very different immigration outcomes across countries. The key is to identify what the employee’s permission depends on and whether the deal changes that condition.

• Employer-specific work permits
  Many permits are tied to a named legal employer. If employees move to another entity after an asset purchase, carve-out or internal transfer, new sponsorship or a fresh application may be required.
• Corporate relationship requirements
  Intracompany transfer routes often depend on a qualifying relationship between parent, subsidiary, affiliate or overseas employer. A divestment or ownership change can break that link even when the employee’s role stays the same.
• Sponsor licence and registration systems
  Some countries require the employer to hold a sponsor licence or register with immigration authorities before hiring foreign nationals. These permissions may not transfer automatically when ownership changes, and missed reporting deadlines can affect the whole sponsored population.
• Role, salary and occupation conditions
  Work authorisation may be linked to a specific job title, occupation code, salary level or seniority. Changes introduced during integration can trigger an amendment or a new application.
• Work location restrictions
  A permit may be valid only for an approved site, region or client location. Remote and hybrid arrangements can therefore create risk where the employee’s actual workplace differs from the address recorded in the original filing.
• Employee-led immigration routes
  Some permits give the individual greater freedom to change employer. Even then, the employee or company may still need to report the change, update documents or meet new salary and role requirements.

The immigration outcome must be determined employee by employee, based on local law, the permit held and the specific changes introduced by the transaction.

Remote and Hybrid Work Can Expose Immigration Record Gaps

Remote work has widened the gap between what immigration records say and where employees actually work.

A permit may have been approved for a specific office, city, region or client site, while the employee now works from home, another branch or a different country. In some jurisdictions, that change can affect the validity of the permit, the applicable salary threshold or the employer’s reporting obligations.

M&A due diligence can bring these discrepancies to the surface. The buyer may inherit sponsored employees whose current work arrangements no longer match the location, duties or reporting line recorded in the original application.

The review should compare immigration records with the employee’s actual working pattern, including:

• registered and current work locations;
• home-working arrangements;
• cross-border remote work;
• client-site assignments;
• recent changes to role, salary or reporting line;
• notifications or amended filings already made.

Where the record and reality no longer match, corrective action may be required before the employee transfers or continues working under the new ownership.

Immigration Compliance Continues After the M&A Deal Closes

Closing does not end the immigration work. It often starts a new round of notifications, filings and employee-level actions across the affected countries.

Post-closing requirements may include:

1. notifying immigration authorities of changes to ownership, employer, work location or role;
2. applying for replacement sponsor registrations or new work permits;
3. updating dependant applications linked to the principal employee;
4. tracking permit renewals and expiry dates during integration;
5. correcting pre-existing compliance gaps identified in due diligence;
6. withdrawing sponsorship and closing immigration files for terminated employees;
7. assessing the effect of redundancies on pending permanent residence applications;
8. meeting return-travel or repatriation obligations where local rules require them.

The timing of these actions matters. Some countries impose short reporting windows after a corporate change, while others require approval before the employee can continue working under the new arrangement.

A clear post-closing immigration plan should assign responsibility for each filing, identify employees who cannot move immediately and confirm how workforce continuity will be maintained while approvals are pending.

How a Global Employer of Record Supports Workforce Continuity in M&A

A Global Employer of Record provides the international employment infrastructure needed to keep employees working across multiple countries when the buyer cannot transfer them directly into its own local entities at closing.

It offers a temporary or longer-term employment solution through established in-country infrastructure, covering compliant local employment, payroll, statutory contributions, benefits administration and, where available, immigration support.

This is most relevant where:

• employees must leave the seller’s employment by a fixed date;
• the buyer’s local employing entity is not yet ready;
• a carve-out creates a stranded workforce in one or more countries;
• a small country team needs to remain operational without immediate entity setup;
• key hires are needed during the integration period;
• work permit sponsorship through the EOR is legally available;
• employees will transfer into the buyer’s own entity at a later stage.

The EOR becomes the local legal employer, manages compliant employment contracts, payroll, statutory contributions, benefits administration and day-to-day employment support. Where permitted, it may also sponsor work permits or support new immigration applications.

The Employer of Record arrangements still require employee-level immigration review. Existing permits do not automatically transfer simply because the employee moves to an EOR. The country, permit category, current sponsor, role and timing must all be assessed before the employment move is confirmed.
