Immigration Advice Service (IAS) is one of the UK's largest IAA-regulated (formerly OISC) immigration advice networks, with London offices and a nationwide presence. The organisation provides regulated immigration advice across all UK visa categories including Skilled Worker, family visas (Spouse, Partner, Parent, Child), student visas, asylum claims, and settlement applications. IAS staff are trained and regulated by the Immigration Advice Authority, formerly the Office of the Immigration Services Commissioner (OISC). The service is particularly accessible for vulnerable clients and has multilingual advisers covering Urdu, Hindi, Bengali, and Somali.
