You will receive a citizenship invitation letter from the Home Office and you need to contact the Registration Office specified on the letter within 14 days. The Registrar will ask you to confirm the 'Poll Number' and the 'Certificate Cover Note ' shown on the invitation letter. The Registrar also needs to see the invitation letter before the Citizenship Ceremony can be arranged.
The final step of becoming a British citizen is to attend a Citizenship Ceremony which you need to arrange with the Registrar (The ceremony must take place within 3 months from the date entered on the invitation letter).
You will receive your Certificate of Naturalisation or Registration directly after the ceremony.
