If you are unsatisfied with the level of service that you have received from any section of the Embassy, there are procedures for registering your complaint.

If you wish to complain about the service you received from the UK Border Agency at this Embassy, please address your complaint to Visa_ComplaintsNY@fco.gov.uk. You may also address your complaint to the Entry Clearance Manager at British Consulate General on 845 Third Ave, 10th Floor, New York, NY 10022, USA

If you have a complaint about the Consular Service you have received, please write to the FCO Director of Consular Services at the address below:

Consular Directorate,
Foreign and Commonwealth Office
Old Admiralty Building,
Spring Garden,
London, SW1A 2PA.
Phone 020 7008 1500;
Fax: 020 7008 0152;
E-mail: complaint.consular.service@fco.gov.uk

They will investigate your complaint fully. The director will see all complaints, and will ask for the investigation to be carried out by a member of staff who is not directly connected to your case or to your complaint. This person will usually be senior to any officer who a complaint has been made against.
We will do our best to give you a full reply within 20 working days. If we cannot give you a full reply within this time, we will tell you when we expect to do so.

Any other complaints should be addressed, in writing, to Stephen Townsend at the Embassy.
