A citizenship ceremony may vary slightly depending on where it is held but all ceremonies will contain several common elements, such as a speech made by the registrar, an oath of allegiance or affirmation of an oath and a pledge of commitment.
All new citizens will be asked to either swear the oath or affirm the oath. If you decide to swear the oath you will be swearing to God, while affirming the oath does not have any religious context.
Swearing the oath:
I (your full name) swear by Almighty God that on becoming a British citizen, I will be faithful and bear true allegiance to His Majesty King Charles the Third, his heirs and successors according to law.
I (your full name) do solemnly, sincerely and truly declare and affirm that on becoming a British Citizen I will be faithful and bear true allegiance to His Majesty King Charles the Third, his heirs and successors according to law.
Pledge of commitment
After swearing or affirming, you will then make the pledge of commitment:
I will give my loyalty to the United Kingdom and respect its rights and freedoms. I will uphold its democratic values. I will observe its laws faithfully and fulfil my duties and obligations as a British citizen.
The group will repeat both the oath and pledge after the registrar, so you do not have to memorise anything.
