UK Immigration Solicitors Specialising in Employer Sponsorship
Since the end of free movement following Brexit, UK employers seeking to hire non-settled workers must hold a sponsor licence issued by the Home Office. The Skilled Worker visa route—which replaced the former Tier 2 (General) category—requires employers to demonstrate that the role meets minimum salary thresholds and skill levels. Navigating this framework demands specialist legal guidance, and the UK has a well-established ecosystem of immigration solicitors who focus specifically on employer sponsorship matters.
Regulatory Landscape
Immigration legal services in the UK are regulated by two principal bodies. Solicitors fall under the Solicitors Regulation Authority (SRA), while non-solicitor advisers are regulated by the Immigration Advice Authority (formerly OISC), which oversees approximately 1,600 organisations and 3,100 registered advisers. Both regulators enforce competence standards, but SRA-regulated firms typically offer the broader legal capability required for complex corporate sponsorship work, including employment law crossover, litigation support, and judicial review.

Choosing the Right Firm
Key selection criteria for HR directors and talent acquisition leads include:
- Sector experience—firms with track records in your industry understand the specific SOC codes, going rates, and compliance risks
- Dual immigration-employment capability—sponsor compliance intersects heavily with employment law, especially around right-to-work checks and TUPE transfers
- Home Office relationships—some firms employ former Home Office caseworkers, which provides insight into audit priorities and decision-making patterns
- Geographic reach—if you sponsor workers across multiple UK sites, a firm with regional presence can manage compliance visits more effectively
