About Ed

Ed Wanambwa is a partner and leads Russell-Cooke’s London-based immigration team.

He advises UK and overseas businesses on complex, high-value and often strategically important UK immigration matters, including a focus on sponsor licence applications, sponsorship compliance, Skilled Worker and Global Business Mobility routes, senior executive mobility and Home Office risk management.

Ed has more than 20 years’ experience advising national businesses, major multinationals, listed companies, investment funds, private equity firms, professional services firms, technology companies, energy businesses, retailers, healthcare providers and other organisations on the UK immigration issues that affect their people and operations.

He advises on sponsor licence applications, changes to sponsor licence structures, Certificates of Sponsorship, Skilled Worker applications, Global Business Mobility routes, senior executive visa applications, Home Office reporting obligations, compliance audits and urgent remedial action where sponsor licence risk has arisen.

Clients value Ed’s ability to make difficult Home Office requirements more intelligible, to give clear and practical advice, and to anticipate the immigration issues that can arise from growth, restructuring, international recruitment, executive appointments and regulatory scrutiny by the Home Office.

Ed also has significant expertise in the immigration implications of corporate transactions and reorganisations, including share acquisitions, business disposals, intra-group restructures, TUPE transfers, administrations and other ownership or operating changes affecting sponsor licence holders and sponsored workers. He has a 100% success rate with all sponsor licence applications, all with the highest possible A-rating, and visa applications he has submitted since qualifying as a solicitor in 2003.

He is personally ranked by all three leading independent legal directories in the UK: The Legal 500, as a Leading Individual, Chambers and Partners and Best Lawyers in the field of UK immigration law. He has previously received numerous awards, including international awards and being chosen as international business immigration lawyer of the year in England.

Ed has for many years provided other lawyers with training relating to business immigration, including via talks to other leading law firms and the Employment Lawyers Association (ELA).

Ed Wanambwa has always been extremely helpful and knowledgeable. His team is responsive and professional, and I can always rely on him to take care of our clients needs.

Special immigration projects
