Specialist Roles

Immigration Adviser

Specialists who advise and represent clients on immigration, asylum, and nationality matters — a regulated profession requiring OISC registration or legal qualification.

Overview

Immigration advisers help individuals and families navigate the complex UK immigration system — from visa applications and settlement to asylum claims and deportation challenges. The field is one of the most fast-moving and emotionally charged areas of legal practice.

Immigration advice is a regulated activity in the UK. Advisers must either be qualified solicitors or barristers (regulated by the SRA or BSB) or be registered with the Office of the Immigration Services Commissioner (OISC) at the appropriate level. OISC registration involves three levels: Level 1 (basic advice), Level 2 (casework and applications), and Level 3 (advocacy and complex cases including appeals).

Immigration advisers work in a variety of settings: law firms specialising in immigration, not-for-profit organisations (such as refugee charities and law centres), the government sector, and as sole practitioners. The work ranges from straightforward visa applications to life-or-death asylum cases involving persecution, torture, and human trafficking.

The field has grown enormously in recent years due to increased demand for immigration services post-Brexit, the asylum backlog, and the complexity of the points-based immigration system. There is strong demand for qualified immigration advisers, particularly those willing to work in legal aid and the not-for-profit sector.
