Complain about an adviser

You can complain to the Office of the Immigration Services Commissioner (OISC) about either:

  • bad service you received from an adviser registered with OISC
  • immigration advice you received from an unregulated person

You can also ask someone to make a complaint on your behalf, for example a friend, solicitor or voluntary organisation.

There’s a different way to complain about a legal adviser registered with a professional body but not regulated by OISC.

What you can and cannot complain about

You can complain about:

  • poor advice or service
  • unreasonable fees
  • an adviser claiming you’ll be successful
  • an adviser charging for work not done
  • an adviser missing deadlines or failing to appear in court
  • an adviser

You cannot make a complaint about:

  • how long your immigration application has taken
  • something that’s already part of an ongoing legal action
  • a refund or compensation
  • Home Office staff
  • a person or organisation outside the UK

You usually cannot make a complaint about something that happened more than 12 months ago - OISC will decide whether or not to investigate depending on the situation.

OISC may refer your complaint elsewhere if you complain about a solicitor or barrister.
