This Practice Note addresses frequently asked questions (FAQs) around immigration options for persons wishing to set up a business in the UK.UK business immigration has become progressively more restrictive in recent years. The closure of legacy routes, most notably Tier 1 (Entrepreneur), Tier 1 (Investor) and the Start-up route, has removed the pathways that were specifically designed to enable entrepreneurs and investors to relocate to the UK. In their place, the Home Office has introduced newer categories, including Innovator Founder, which can be more rigorous and evidence-heavy.There is a clear trend in Home Office policy and decision making as regards business owners and entrepreneurs. Applicants are increasingly expected to show that the business is already established, or that there is a realistic and credible business model which will ensure that the business is ready to trade in due course. In practice, it is now significantly harder to secure UK immigration permission based solely on an intention to set up a business in the UK.
