About Us

The Immigration Department is well-known for representing highly vulnerable clients – young people, victims of trafficking and the mentally ill – , as well as high risk offenders. The Department’s clients have often been failed by previous solicitors or have been too unwell to present their claim. We are known for being able to take the more complex claims at short notice, for being successful in stopping removal and obtaining a successful end result for the client.

Due to the nature of our work, we cannot name particular clients. We receive referrals from, and work closely with, a number of leading NGOs and other organisations, including the Helen Bamber Foundation, Freedom from Torture, Amnesty International UK, Southall Black Sisters, the UK Lesbian & Gay Immigration Group, the Refugee Council and others, as well as from barristers and other solicitors.

The firm has been rated as ‘excellent’ following a detailed peer review.
