Business immigration

Business immigration: Opening doors to the UK

Expanding your business to the UK offers exciting opportunities. But it’s important to make sure your business and key personnel comply with UK immigration laws. The UK has strict immigration rules, and there are significant consequences for non-compliance – including civil penalties starting at £45,000, criminal liability and reputational damage for employers.

Navigating the routes: What you need to know

There’s a wide range of economic immigration routes into the UK, each with its own eligibility criteria and considerations. Immigration is a political issue in the UK – so staying up to date with the changing rules is essential. If you’re based overseas, understanding the regulations and identifying the correct route for each individual can be daunting.

Below are key questions to ask:

Who needs a visa to travel to the UK on business visits?

Some nationalities must get a visit visa before travelling to the UK. Others can enter as visitors but need an electronic travel authorisation (ETA) first. This is dictated by nationality. The UK’s visitor rules are strict on what business visitors can do and how long they can stay. Breaching these rules can mean illegal working, so carefully check if a different visa is needed.

Are your plans more than a business visit?

If your people need to do more than a visitor is allowed or stay longer, you’ll need a different visa. There are a variety of options available, and the right route will depend upon factors such as:

  • Whether your business is already established in the UK and, if so, its legal structure and stage of development.
  • What UK-based personnel your business has already (if any).
  • What the individual will do in the UK, for how long and your longer-term plans for them.
  • How much they will be paid.
  • Their personal circumstances (e.g., qualifications, nationality and age).

Some routes are employer-led and will require your UK business to secure a sponsorship licence from UK Visas and Immigration.

Is immigration part of your expansion strategy?

If your key people aren’t British or Irish nationals, immigration must be front and centre when planning your UK business. The way you set up your UK business could rule out some immigration options, so get expert advice at an early stage.
