What is an Accredited Specialist in Immigration Law?

In the legal profession, an Accredited Specialist in Immigration Law is a solicitor who has demonstrated high level of competence in Australian immigration law and policies and has been awarded Specialist Accreditation by the Law Society.

To become an Accredited Specialist in Immigration Law a solicitor must complete at least five years of practice with at least three years of extensive experience in immigration law. They are then required to undertake and pass the Law Society’s rigorous oral and written examinations. To maintain Specialist Accreditation, they must undertake on-going training in the area of immigration law, in addition to that required of other solicitors.
