Firms To Watch: Immigration

Founded in 2020, boutique immigration firm Helen Smith Immigration Ltd has a fast-growing team and significant experience in the digital and technology sectors.

Immigration in South East

Birketts LLP

Led by Sacha Wooldridge following the July 2021 departure of Clare Hedges, Birketts LLP‘s immigration team works across the firm’s Norwich, Ipswich, Chelmsford and Cambridge offices to act for clients across the South East and beyond. The firm predominantly focuses on business work, with particular experience in procuring skilled worker visas and supporting clients in the farming and agricultural sector. Chelmsford-based practitioner Janice Leggett is a key contact, with a niche specialism in advising clients in the advertising sector on how to bring film crews to the UK. The team is also adept at handling personal immigration matters, including spouse visas, citizenship applications, and global talent visas for entrepreneurs.

Janice Leggett


‘Birketts are extremely professional, responsive, and helpful. They are experts in immigration law. I have complete confidence in them. I feel safe in their hands. I trust them implicitly. Over the years, they have helped me with my immigration applications in extremely challenging situations (e.g. obtaining work visas in very short periods of time). Birketts’ legal advice is top-notch and cost-effective; it represents excellent value for money. Birketts bring a humane approach and a personal touch to the practice of immigration law.’

‘I was particularly impressed by Sacha Wooldridge.’

‘Very recently, I had to secure my Indefinite Leave to Remain visa in order to take up a post at a different university. I had only about a month in which to obtain my ILR visa. This was in January, 2022, a time of unprecedented uncertainty and change, a time when the Home Office had a crushing backlog due to COVID-related shortage of staff. Thus, obtaining the ILR visa in time seemed like a very challenging undertaking. However, true to form, Janice Leggett at Birketts got the job done, and helped me secure my ILR visa in near record time. I cannot express my gratitude warmly enough to Janice and Birketts. My life would be very different if it weren’t for them. I owe them a massive debt of gratitude. They are performing a great service for foreigners like me who have chosen to live and work in the UK.’

‘They are unique because of the efficiency and dedication they showed to their client.’

‘There are 2 things this practice does that makes them stand out 1. Simplifying the Complex: Immigration applications can be a complex and intimidating process, but Birketts’ team (led by Janice) has always made the entire process very simple for me. Their accompanying documentation and emails always make things a breeze for me. 2. Approachability: No question to small or big, no matter what I have on my mind, I can ask them for clarification, confirmation etc. Other firms that I have worked with before do not offer such care and attention to detail.’

‘Janice Leggett is a gem of a human being, she has always been there for me throughout the years as an immigration adviser. Even when I was almost scammed in an immigration fraud and I reached out to her out of the blue for advice, she was there to answer my questions, and even gave me advice. This makes her a rare breed. I am so grateful that I have had the distinct pleasure of working with her (and her wonderful team) who are approachable and ever so helpful.’

‘Very approachable, so helpful, could not fault.’
