UK Business Immigration – Immigration Law Specialists for Employers, Founders & Investors

UK business immigration covers the visa and sponsorship routes that allow overseas companies, entrepreneurs and skilled professionals to establish, invest and work in the United Kingdom. The main routes are the Sponsor Licence and Skilled Worker system for UK employers, the Innovator Founder visa for entrepreneurs, and the Expansion Worker visa for overseas businesses opening their first UK presence.

The route you choose shapes everything that follows: how quickly you can hire or trade, what evidence UK Visas and Immigration (UKVI) will demand, what your ongoing compliance duties look like, and whether the route leads to settlement. This page explains each route in plain English, shows who each one is designed for, and sets out the pitfalls behind most refusals – so you can commit to the right strategy first time.

Conroy Baker Ltd is a team of UK immigration consultants in London advising employers, founders and investors across the United Kingdom, the United States, Canada, Europe and the Middle East. Conroy Baker pairs immigration advice with practical business support – UK market research, international recruitment and growth planning — so the visa strategy and the commercial plan move together rather than in sequence.

• Sponsor licence application fee: £574 for small sponsors, £1,579 for medium and large sponsors (as at July 2026).
• Standard sponsor licence decisions take around 8 weeks; a priority service of around 10 working days is available in limited daily numbers.
• Skilled Worker general salary threshold: £41,700 per year, with different figures for some roles and occupation lists (as at July 2026).
• Innovator Founder visa: endorsement required before applying; settlement (Indefinite Leave to Remain) possible after 3 years.
• UK Expansion Worker visa: capped at 2 years in total; it does not lead directly to settlement.

Route selection is the highest-value decision in UK business immigration. Made well, it saves months and avoids a refusal that follows the business around. These are the three situations we advise on most often.

The sponsor licence and Skilled Worker route is almost always the answer. The real question is readiness. UKVI expects genuine vacancies, salaries and skill levels that meet the thresholds, and HR systems capable of monitoring sponsored staff from day one. Our advice usually starts with an audit of those systems before any application is filed, because a licence granted to an unprepared sponsor is often a licence suspended at the first compliance visit.

If you have no UK trading presence yet, the Expansion Worker route puts your senior people on the ground. Plan the whole journey at the outset – provisional licence, UK entity, first hires, then the switch to a full Skilled Worker licence – because decisions made in month one determine whether the two-year cap becomes a problem in month eighteen.

The Innovator Founder visa suits founders with a genuinely innovative business and a credible plan. Self-sponsorship can suit established business owners bringing a proven model to the UK. The two routes differ sharply in evidence, cost and settlement timeline, and the right choice depends on your business and your long-term goals – not on which application form looks simpler.

Business immigration applications are rarely decided by the form. They are decided by whether the underlying business case stands up to scrutiny.

For employers, UKVI examines whether the organisation is genuine and solvent, whether the roles are credible at the stated salary and skill level, and whether HR systems can track sponsored workers’ attendance, contact details and right to work. Weakness in any of these invites a refusal, or a licence granted and then suspended after a compliance visit. UKVI’s employer sponsorship guidance on gov.uk sets out the formal duties in full.

For founders, endorsing bodies and UKVI look for innovation that is more than a variation on an existing model, evidence the plan is viable with the resources you actually hold, and a credible personal role in delivering it. Generic, templated business plans are the most common single reason endorsement fails.

In every route, evidence beats assertion. Trading history, contracts, financial records, organisational charts and properly documented HR processes decide these applications – and they are exactly what we build with clients before anything is submitted.

Budget for three layers of cost: government application fees, the Immigration Skills Charge and Immigration Health Surcharge where they apply, and professional fees. Government fees change regularly – often in April – so confirm current figures against gov.uk or with an adviser before committing budgets or making offers to candidates.

Timelines follow the same logic. The published processing time is only the final stage. Realistic planning runs from evidence-gathering through submission to decision. For employers, allow several weeks to prepare HR systems and supporting documents before the licence application, then around eight weeks for a standard decision. For founders, endorsement adds a stage before the visa application itself.

Two planning rules serve every client well. First, sequence backwards from the commercial deadline – a product launch, a contract start date, a new hire’s notice period – rather than forwards from the application date. Second, build in contingency for requests for further information, which pause the clock and are common in business routes.

We publish anonymised case studies because outcomes are better evidence than adjectives. Three recent examples show how route strategy plays out in practice.

A Portuguese entrepreneur came to Conroy Baker with an innovative business concept and a long-term goal: permanent settlement. We planned the full pathway from endorsement through ongoing compliance checkpoints to Indefinite Leave to Remain (ILR), and the client secured settlement in three years while building the business. Route strategy, not paperwork, made the difference.

An overseas business in Jeddah needed a UK sponsor licence and ongoing Certificate of Sponsorship management to grow its UK operations. Conroy Baker handled the licence strategy, the application and CoS allocation planning, giving the company a compliant hiring pipeline between Saudi Arabia and the UK.

When a UK employer’s request for an undefined CoS allocation stalled and put recruitment timelines at risk, we reviewed the request history, assessed the compliance position and escalated the matter through the appropriate legal channels — protecting business continuity during a critical period.

Five patterns sit behind most UK business immigration refusals we are asked to repair.

1. Choosing the route by cost rather than fit. The cheapest application is expensive if it is the wrong route. A refusal stays on the record and complicates every application that follows.
2. Templated business plans. Endorsing bodies and UKVI read hundreds of plans. Generic documents signal a non-genuine application, however strong the underlying business may be.
3. Applying for a sponsor licence before HR systems are ready. The application invites scrutiny of your monitoring and record-keeping. If those systems only exist on paper, a compliance visit will find out.
4. Treating the licence as the finish line. Sponsor duties continue for the life of the licence. Unreported changes and missing records are the usual triggers for suspension or revocation.
5. Ignoring the settlement endgame. Routes differ in whether and when they lead to ILR. A two-year route chosen casually can cost a founder and their family several extra years.

We advise end to end: route strategy and eligibility, application preparation and submission, sponsor licence set-up, Sponsor Management System (SMS) operation, ongoing compliance and renewals, and escalations when something has already gone wrong.

Because Conroy Baker also provides UK market research, international recruitment and growth support, business clients get one adviser for the immigration plan and the commercial plan behind it – a combination most immigration practices do not offer.

Engagements typically follow four stages: a consultation to confirm the route and surface risks; an evidence and readiness plan; preparation and submission of the application; and, for sponsors, ongoing compliance support covering the SMS, reporting duties and renewals. At each stage you know what has been done, what comes next and what it costs.

Conroy Baker’s advisers are IAA-regulated (formerly OISC), registration F202200094, Level 1. General content on this page is information, not advice; personal advice is given in consultation by a qualified adviser.

A large share of Conroy Baker’s business clients are based outside the UK: employers and founders in the United States, Canada, Europe and the Middle East planning a UK hire, entity or launch. Distance changes the logistics, not the advice. Consultations are held remotely, documents move through secure channels, and the strategy is built around your time zone and your commercial calendar.

For overseas businesses, the usual sequence pairs an Expansion Worker or sponsor licence strategy with practical market-entry support: UK market research to validate the opportunity, recruitment planning for the first UK hires, and a compliance framework that works from day one. Running these in parallel is one of the clearest advantages of combining immigration and business advisory under one roof.
