Update from The Home Office:
"Government restrictions in relation to COVID-19 have understandably restricted the ability of local authorities to provide citizenship ceremonies, as the safety of customers must be paramount
Whilst we will continue to work closely with our local authorities to expand the provision of citizenship ceremonies, including the expansion of availability of virtual ceremonies, due to the changing restrictions and guidance relating to COVID-19, it is not possible at this time to advise when a certificate will be despatched once an application has been approved.
However, we can confirm that we have just completed the processing of certificates and ceremony invitations for applications that were approved on and before 3 November and have now commenced processing those for applications approved on 4 November 2020. Ceremony invites are sent by 2nd class post and can take up to 10 working days to be delivered.
We will update our website with any new information, in particular, in relation to the time it might take to despatch certificates. Please be assured that once a customer receives their Citizenship Ceremony Invitation Letter, they will still have up to six months within which to complete ceremony.
Exceptional circumstances relating to an urgent need to complete a British citizenship ceremony will, of course, be taken into consideration, with the appropriate supporting evidence. If you need to undertake a ceremony urgently, please contact us at Citizenship.Support@homeoffice.gov.uk. However, we are unable to guarantee that we will able to expedite any ceremony request at this time.
We would ask that you do not contact us, or your local authority, regarding your ceremony at this time and be assured that we are working as quickly as possible to despatch your certificate. Your patience and understanding at this time are much appreciated."
