Anyone providing immigration advice without being registered with OISC or exempt is committing a criminal offence. Every registered or exempt advice organisation should display a certificate issued by the OISC showing that it meets the OISC standards. You can contact the OISC at:

5th Floor
Counting House
53 Tooley Street
London
SE1 2QN

Helpline: 0845 000 0046
Website: www.oisc.org.uk

A full listing of all registered and exempt advisers and advice organisations can be found on the OISC website, which also explains how to make a complaint about an immigration adviser. You should note that the OISC does not deal with enquiries about immigration problems.
