Let me begin by thanking you for this beautiful place where we can seek for some legal advices. I have been living in the UK for a little more than three years as a non EEA spouse of an Italian citizen. However, I am getting Italian citizenship in a week through Italian Consulate in London. Do I need to inform Home Office or other government agencies once I get my Italian citizenship as I want to reside here as an Italian? Thanks.
Thank you for your kind words.
You are not required to inform Home Office/UKVI of your new citizenship, however, when you file your Permanent Residence application, it is advisable to explain this change in citizenship in that application.
