An Overview of Sponsoring International Employees in the UK

Sponsoring an international employee in the UK is one of the most effective ways to fill critical skills gaps and bring diverse perspectives into your organisation. The process, however, involves strict legal responsibilities, detailed paperwork, and ongoing compliance obligations. Getting it right from the start saves time, money, and avoids Home Office sanctions. This expanded guide covers the essential steps, from obtaining a sponsor licence to supporting your new hire and maintaining long-term compliance.

Obtaining a Sponsor Licence: What Your Business Must Prove

Before you can assign a Certificate of Sponsorship (CoS) to an overseas worker, your business must first secure a sponsor licence from the UK Home Office. This is not a simple checklist exercise; the Home Office scrutinises your company’s genuineness, HR processes, and ability to meet sponsor duties.

Eligibility Criteria

Your organisation must be a genuine entity operating lawfully in the UK (or a UK branch of an overseas firm). You need to demonstrate that the roles you intend to fill are genuine vacancies that cannot be easily filled from the resident labour market (although the current shortage occupation list and new immigration salary list can simplify this). The Home Office also checks that you have no unspent criminal convictions for immigration or certain other offences.

Key Documentation for the Licence Application

Prepare these documents well in advance:

  • Proof of registration: Companies House certificate, VAT registration, or equivalent for charities and partnerships.
  • Evidence of genuine trading: Recent bank statements, PAYE records, and audited accounts.
  • HR systems document: A description of how you will track employees’ right to work, absences, and contact details.
  • Organisation chart showing the role’s position and reporting lines.
  • Job advertisements or evidence of the “resident labour market test” if applying under older eligibility rules (though this test is no longer required for most Skilled Worker applications, you may still need to show the role meets the skill level and salary).

The Home Office aims to process licence applications within 8 weeks, but delays can occur if documents are incomplete. Consider using the priority service if your business needs to hire urgently.

Selecting the Right Visa Category for Your Employee

The Skilled Worker visa is the most common route, but it is not the only option. Choosing the correct category reduces the risk of refusal and ensures you meet specific salary and skill thresholds.

The Skilled Worker Visa: Key Requirements

  • Job at RQF 3 or above: The role must be skilled to at least A-Level equivalent (RQF Level 3 on the new occupation codes).
  • Minimum salary: Generally £26,200 per year or the ‘going rate’ for the occupation, whichever is higher. Lower rates apply for shortage occupations and new entrants (e.g., recent graduates).
  • English language: The employee must prove English proficiency (e.g., an approved test, a degree taught in English, or being a national of a majority English-speaking country).
  • Sufficient funds: The worker must show they can support themselves in the UK (usually £1,270 held for 28 consecutive days, unless the employer certifies maintenance).

Other Relevant Routes

For executives, researchers, or individuals with exceptional talent, consider the Global Talent visa (no salary threshold or sponsorship required) or the Senior or Specialist Worker visa (Global Business Mobility route). For short-term assignments, the Scale-up Worker visa can be suitable if the employee will be sponsored by a qualifying scale-up business. Always cross-check the specific eligibility requirements on the UK government’s work visa page.

Preparing Complete and Accurate Documentation

Incomplete or inconsistent documents are the leading cause of visa refusals. Every piece of evidence must be correct, current, and ideally presented in the recommended format (PDF, scanned colour copies).

Documents Your Business Must Provide

  • Certificate of Sponsorship (CoS): This is an electronic record generated through the Sponsor Management System (SMS). The CoS must include the correct job code, salary, working hours, and details of any skills or experience requirements.
  • Alternative evidence for genuine vacancy: If the Home Office suspects the role is not genuine, they may request additional business evidence (e.g., financial projections, client contracts). Be ready to justify why the role is needed and why it cannot be filled domestically.

Documents the Employee Must Submit

  • Passport (valid for the duration of the visa).
  • Proof of English language ability (e.g., SELT certificate from an approved provider).
  • Educational certificates (if relying on a degree or professional qualification to meet the skill level).
  • Bank statements showing the required maintenance funds (or a declaration from the employer that they will cover costs for the first month, if using the concession).
  • TB test certificate if the employee is from a listed country.

Double-check that all names match across documents. A small typo can cause a delay or refusal. Provide a clear, structured file naming convention (e.g., “Smith_John_Passport.pdf”) to speed up processing.

Sponsorship Duties and Ongoing Compliance

Holding a sponsor licence comes with a detailed list of duties. The Home Office expects you to cooperate with any compliance visits, keep accurate records, and report certain events within a set timeframe.

Key Duties at a Glance

  • Record keeping: Maintain copies of employees’ passports (including BRP or eVisa details), contact details, absences, and any changes in employment status for the duration of sponsorship plus two years after.
  • Reporting: Notify the Home Office within 10 working days if the employee is absent without permission for 10 or more consecutive days, stops working, changes job role, or if you end sponsorship.
  • Right to Work checks: Perform statutory right-to-work checks before the start of employment. For Skilled Workers, you must also check that the employee holds a valid visa or has applied before their previous visa expires.
  • Sponsor Management System (SMS) management: One person in your business must be the Authorising Officer, with overall responsibility for sponsorship. Two other roles (Key Contact and Level 1 User) should also be assigned to ensure continuity.

Compliance Visits and Audits

The Home Office conducts unannounced compliance visits. Be prepared to produce employee files, payroll records, and proof of ongoing compliance at short notice. A common pitfall is failing to track employee absences or not updating the SMS when a sponsored worker leaves. Non-compliance can lead to licence downgrades, suspension, or revocation. For a detailed breakdown of sponsor duties, refer to the official Home Office sponsorship guidance.

Supporting Your Employee Throughout the Visa Process

The visa application process can be stressful for new hires. Proactive support from the employer improves the employee’s experience and reduces the chance of errors that could delay the visa.

Practical Ways to Help

  • Provide a clear timeline: Explain the stages – CoS assignment, visa application, biometric appointment, decision, and travel to the UK. Set realistic expectations for processing times (typically 3–8 weeks for standard decisions, but priority/ super-priority options are available).
  • Document review: Before the employee submits their online application, ask them to send you a draft of the application form. Check for inconsistencies with the CoS (e.g., salary, job title, start date). This simple step prevents mismatches that can trigger refusal.
  • Cover costs or provide a maintenance letter: If the employee is struggling to show sufficient maintenance funds, you can certify their maintenance on the CoS. This means you guarantee to cover their costs for the first month – a huge help for early-career workers or those with financial constraints.
  • Immigration Health Surcharge (IHS): The employee must pay the IHS (currently £624 per year for most workers). Your company can choose to reimburse this as a retention benefit, but it is not mandatory. Include the IHS amount in any relocation package discussion.

Onboarding After Arrival

Once the employee arrives in the UK, arrange a thorough onboarding session covering: right-to-work confirmation, bank account opening (some banks need a letter from the employer), tax code (many need to contact HMRC to correct an emergency code), and rental accommodation. A dedicated HR contact for the first 90 days can help the new hire settle quickly.

Sponsoring international employees is not cheap. The total cost per worker can easily exceed a few thousand pounds, depending on the visa type and whether you use legal support. Understanding the costs upfront helps you budget and decide whether to pass on any fees to the employee (though some fees are legally barred from being passed on).

Typical Expenses

  • Sponsor licence application fee: £536 for a small company (or £1,476 for a medium/large company, based on your size band as defined by the Home Office).
  • CoS fees: £199 per unrestricted CoS (or £21 per restricted CoS for jobs on the general quota, but most Skilled Worker roles now use unrestricted CoS).
  • Visa application fee: £719 for a 3-year visa (standard duration) and higher for longer stays; depends on the occupation and whether it’s a shortage role.
  • Immigration Health Surcharge: £624 per year (increasing to £1,035 per year from early 2025 for some categories – check current rates on the UK government IHS page).
  • Legal and immigration fees: If you use an immigration solicitor (recommended for complex cases), expect £500–£2,000 per application.
  • Cost of repatriation if the employee leaves: While not a direct fee, consider the cost of finding a replacement and the risk of losing the CoS if the worker leaves early.

Note that by law you cannot charge the employee for the CoS or the cost of a compliance visit. However, you can agree to reimburse the visa application fee and IHS if you wish to make the offer more attractive.

Staying Ahead of Changing Immigration Policies

UK immigration rules have seen frequent changes, especially after Brexit and the introduction of the new immigration system in 2021. Keeping up with policy shifts is essential to avoid costly mistakes.

How to Stay Informed

  • Subscribe to Home Office updates: The government’s immigration statistics quarterly release often signals upcoming changes. Also sign up for email alerts on the UK Visas & Immigration page.
  • Join a professional network: Organisations like the Immigration Law Practitioners’ Association (ILPA) publish regular briefings on new policies.
  • Engage a specialist immigration lawyer: For businesses that sponsor more than 10 workers annually, having a retainer with a reputable law firm (e.g., Fragomen or Smith Stone Walters) can save you from compliance pitfalls.
  • Review your Sponsor Management System regularly: Check for any Home Office alerts about licence changes or new requirements. The SMS will display notifications when your licence is due for renewal or when new sponsor duties are added.

Since the UK left the EU, all EU/EEA citizens who were not resident by December 2020 must be sponsored in the same way as non-EU nationals. The government has also introduced a new ‘Immigration Salary List’ (which replaced the Shortage Occupation List) in April 2024. This list is updated regularly and can affect which roles have lower salary thresholds and reduced visa fees. Keep an eye on this list, as it dictates whether you can sponsor a particular role at a lower cost.

Building a Long-Term International Talent Strategy

Successful sponsorship should not be a reactive process. Forward-thinking businesses integrate international hiring into their recruitment strategy, making compliance a seamless part of HR operations.

Strategic Steps to Take

  • Create a internal sponsor licence handbook: Document your company’s policies on record keeping, reporting, and employee support. Train all hiring managers on the basics of sponsorship so they understand salary thresholds and documentation requirements.
  • Forecast your needs: If you anticipate hiring multiple sponsored workers over the next 12 months, apply for unrestricted CoS well in advance. You can hold a stock of unused CoS (subject to your licence allocation).
  • Partner with several agencies: Build relationships with recruitment agencies that specialise in international talent. They can pre-screen candidates for visa eligibility and help you navigate niche requirements for hard-to-fill roles.
  • Consider a home office compliance role: For medium and large companies, appointing a dedicated immigration compliance officer ensures that sponsorship duties are never overlooked. This role can liaise with external legal counsel and prepare for compliance visits.

Final Checklist for a Smooth Sponsorship Journey

To wrap up, here is a concise list of actions that will keep your sponsorship process on track and protect your business from Home Office penalties:

  • ☐ Review the latest Home Office guidance for sponsor licence holders (updated regularly).
  • ☐ Ensure your Authorising Officer and HR team understand their responsibilities.
  • ☐ Perform a mock compliance audit every 6 months: check employee files, absence records, and SMS reports.
  • ☐ For new hires, assign a mentor or buddy to help with settling in the UK (housing, healthcare registration, etc.).
  • ☐ Keep an eye on the Immigration Salary List and going-rate updates for your industry.
  • ☐ Reassess your visa categories annually: a role that was suitable for Skilled Worker may now be eligible for Global Talent or Scale-up, which could be cheaper or faster.

Sponsoring international employees is a significant commitment, but with careful planning, thorough documentation, and ongoing compliance, it can become a reliable pillar of your talent acquisition strategy. By treating sponsorship as a long-term investment rather than a one-off administrative task, you not only comply with the law but also build a genuinely global workforce that strengthens your organisation.
