Complain to Office of the Immigration Services Commissioner (OISC) about an immigration adviser within the UK if you think you’ve had poor service or bad advice.

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

What you can and can’t 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

You can’t 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 can’t make a complaint about something that happened more than 6 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.
