How to Evidence Overseas Employment for Global Business Mobility Applications
A Practical Guide for Employers Sponsoring Overseas Employees to Work in the UK
The Global Business Mobility (GBM) routes allow eligible overseas businesses to transfer workers to the UK for specific business purposes, including establishing a UK presence, transferring senior employees, or bringing specialist skills into a connected UK entity.
A key requirement across many GBM routes is demonstrating that the overseas worker has been genuinely employed by the overseas entity for the required period and that there is a qualifying relationship between the overseas and UK businesses.
One of the most common reasons for delays or refusals in Global Business Mobility applications is insufficient evidence of the overseas employment relationship. Employers must provide clear, reliable evidence showing that the worker is genuinely employed, appropriately qualified for the role, and eligible for transfer.
This guide explains the types of evidence that can support overseas employment, how to demonstrate the relationship between overseas and UK entities, and common mistakes employers should avoid.
Why Overseas Employment Evidence Matters
For Global Business Mobility routes, the Home Office must be satisfied that:
- The overseas worker has been employed by the overseas business for the required period.
- The employment relationship is genuine and ongoing.
- The worker has carried out a role that meets the requirements of the relevant GBM category.
- The UK and overseas entities have the required qualifying relationship.
- The transfer is for a genuine business purpose and not primarily to facilitate immigration.
The Home Office will assess the credibility and consistency of the evidence provided. Documents should clearly demonstrate the worker’s employment history, salary payments, job duties, and position within the organisation.
Acceptable Evidence of Overseas Employment
There is no single document that proves overseas employment. A strong application usually includes a combination of documents that create a clear picture of the employment relationship.
1. Employment Contract
An employment contract is one of the most important documents to evidence overseas employment.
The contract should confirm:
- The employee’s full name.
- Employer’s legal name and registered details.
- Employment start date.
- Job title and duties.
- Salary and benefits.
- Working hours.
- Terms and conditions of employment.
Where possible, the contract should match the information provided in the GBM application, including the proposed UK role and salary.
Any inconsistencies between the employment contract, Certificate of Sponsorship and supporting documents may lead to additional Home Office enquiries.
2. Payslips and Salary Evidence
Payslips are important evidence that the employment relationship is genuine.
Employers should provide:
- Recent payslips covering the required employment period.
- Evidence of salary payments into the employee’s bank account.
- Payroll records where available.
Payslips should clearly identify:
- The employee’s name.
- Employer details.
- Payment dates.
- Salary amounts.
- Deductions.
Where salary is paid through international payroll systems, employers should provide an explanation of the payment process and supporting financial records.
3. Tax and Social Security Records
Official tax records can provide strong evidence of genuine overseas employment.
Examples include:
- Income tax filings.
- Tax payment records.
- Social security contributions.
- Government employment records.
- Employer payroll submissions.
These documents can be particularly useful where payslips are unavailable or where employment records differ between countries.
4. Organisational Charts
An organisational chart can help demonstrate the employee’s role within the overseas business.
A suitable organisational chart should show:
- The employee’s position.
- Reporting lines.
- Seniority within the business.
- Relevant departments.
- The relationship between overseas and UK teams.
For senior employees, such as those applying under the Senior or Specialist Worker route, the organisational structure can help demonstrate that the employee holds the required level of responsibility.
5. Additional Supporting Evidence
Depending on the circumstances, employers may also provide:
- HR records.
- Employee confirmation letters.
- Performance reviews.
- Internal company directories.
- Work emails or project records.
- Professional licences or qualifications.
- Evidence of business activities undertaken by the employee.
The purpose of supporting evidence is to establish a consistent and credible employment history.
Demonstrating the Relationship Between Overseas and UK Entities
A key requirement for many Global Business Mobility routes is proving that the overseas and UK businesses have a qualifying relationship.
The evidence required will depend on the specific GBM category, but employers should generally demonstrate:
- Common ownership or control.
- A parent and subsidiary relationship.
- A branch relationship.
- A qualifying corporate group structure.
- A joint venture or qualifying connection where applicable.
Evidence of Corporate Relationship
Examples of supporting documents include:
Corporate Documents
- Certificates of incorporation.
- Shareholder registers.
- Company ownership records.
- Group structure charts.
- Annual reports.
- Corporate filings.
Commercial Evidence
- Service agreements between entities.
- Intra-company agreements.
- Business plans.
- Financial statements.
- Evidence of shared operations.
Group Structure Evidence
A clear corporate structure chart should explain:
- The ownership of the overseas company.
- The ownership of the UK entity.
- The relationship between the two businesses.
- Where the transferred employee sits within the wider organisation.
The Home Office must be able to understand why the employee is being transferred and how the UK role supports the business relationship.
Common Evidence Gaps That Cause Refusals or Delays
1. Insufficient Evidence of Employment History
A common issue is providing only a short employment letter without supporting documentation.
A letter confirming employment may not be sufficient on its own. Employers should support it with payroll, tax or HR records.
2. Inconsistent Job Titles or Duties
Applications may be delayed where:
- The overseas job title differs from the UK role without explanation.
- The employee’s experience does not match the proposed role.
- Job descriptions appear generic or unsupported.
Employers should clearly explain any changes in role responsibilities following the transfer.
3. Unclear Corporate Relationship
Applications can fail where employers do not provide sufficient evidence of the connection between the overseas and UK entities.
A company name similarity alone is not enough. The Home Office requires evidence of the actual legal and commercial relationship.
4. Missing Financial Evidence
Where the relationship between companies relies on commercial arrangements, insufficient financial evidence can create concerns.
Employers should consider providing:
- Accounts.
- Contracts.
- Invoices.
- Business records.
- Evidence of ongoing operations.
5. Poor Quality or Unverified Documents
Documents should be:
- Clear and readable.
- Consistent with other evidence.
- Translated where required.
- Properly dated.
- Issued by appropriate authorities or company representatives.
Preparing a Strong Global Business Mobility Application
Employers should prepare evidence proactively rather than waiting for a Home Office request.
A strong application should:
- Identify the specific GBM route requirements.
- Gather evidence of the worker’s overseas employment history.
- Prepare a clear explanation of the corporate relationship.
- Ensure all documents are consistent.
- Address potential weaknesses before submission.
The Home Office guidance emphasises that sponsors must provide documents that demonstrate they meet sponsor licence and immigration requirements, including evidence of their organisation’s structure and activities. Evidence requirements are set out in the Home Office sponsor guidance, including Appendix A.
