定居同入籍唔同,
入籍要宣誓效忠,以英國為例
「I, [name], swear by Almighty God that, on becoming a British citizen, I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth the Second, Her Heirs and Successors according to law. 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. 」
