There are two ways to British citizenship. The first is for those who are married to a British national and the other are for those who are not married to a British national. Note that the two situations below so you can compare how they differ. If you are not sure then speak to a lawyer in Thailand or in the UK for further assistance and advice. See this website for more details.

- If you have already been living in the United Kingdom at the start of those 3 years;
