Contacting the Office of the Immigration Services Commissioner

OISC contact details

To contact the OISC, first use our online portal to ask a query or to make a complaint.

The Customer Service Unit is also available on info@oisc.gov.uk, and they will then pass on the query or documents to the correct part of the organisation.

For Journalist enquiries ONLY, please email: pressoffice@oisc.gov.uk.

Finally, you can call us on 0345 000 0046 between 9am and 4pm, Monday to Friday, except public holidays, and leave a message.

As a fully-remote organisation,  documents sent to the OISC by post will take longer to reach the recipient, but you can send via OISC, PO Box 567, Dartford, DA1 9XW.

Applications for registration and continued registration should be completed online using our electronic application forms (How to complete and upload OISC electronic application forms - GOV.UK (www.gov.uk)). Clear instructions on how to do this are provided with each form.
