Still waiting for Citizenship

Just a quick update...I am still waiting for my Naturalisation Application to be approved...I have noticed that if you used the app the waiting time is extremely beyond 6 months...some people have waited 9 months with a straightforward application...I have gotten my MP involved in February and he was told that my application is at the final stage which is consideration...three Mondays have since gone past with no word from the Home Office...so I am just sitting patiently waiting...

But I do have a question about passports...when I do get my citizenship and apply for my shiny new British passport do I send in all my US passports or just the one with the visa in it...I have 3 passports in total... ;
