Immigration
At Duan & Duan UK LLP, we provide pragmatic, sensible, and strategic advice on British immigration and nationality laws.
We are known for the immigration matters other firms turn away: refusals, appeals, judicial review, complex source-of-funds evidence and applications with adverse history. Our track record includes acting for over 100 investors in R (Wang) v Secretary of State for the Home Department [2023] UKSC 21.
We work closely with our clients to make the process as straightforward as possible, recognising that each client's circumstances and priorities differ and often require a culturally nuanced approach.
We keep up to date with the Immigration Rules and apply them carefully for our clients. With substantial experience in immigration judicial review and appeals, we regularly act in cases challenging Home Office decisions that we consider unlawful or unreasonable.

Personal Immigration
At Duan & Duan UK LLP, we guide private clients and their families through the entire immigration process, from visa and entry clearance applications to extension applications, indefinite leave to remain (ILR), and obtaining British citizenship and passports.
Our dedicated team has extensive knowledge of advising individuals on human rights claims and appeals, and we are well-known for our willingness to challenge policies and lobby on behalf of our clients.
We understand that immigration can be a complex and stressful process, which is why we strive to make it as smooth and stress-free as possible for our clients. Whether you are looking to come to the UK to work, study, join family members, or settle permanently, we are here to help you navigate the immigration process with confidence and peace of mind.
Nationality, ILR & Settlement
Indefinite Leave to Remain (ILR) — settlement — removes time restrictions on living, working and studying in the UK and is the usual route to British citizenship after twelve months, but eligibility and evidence requirements differ significantly between the long residence, family and work-visa routes. See our 2025 guide to Indefinite Leave to Remain.
Immigration Appeals, Admin Review & Judicial Review
At Duan & Duan UK LLP, we understand the disappointment, frustration, and stress that can come with having an immigration application refused.
Our partners have a combined 30 years of experience in challenging the British government's immigration application refusals through various high-profile cases at the Immigration Tribunals, Court of Appeal, and Supreme Court.
We are committed to using our expertise and knowledge to help our clients challenge unfair decisions and obtain the best possible outcomes. We know that each case is unique, and we take the time to understand our clients' specific circumstances and needs. Our team works tirelessly to ensure that our clients' voices are heard and that their rights are protected.
