Unless you are British by descent, to become a UK citizen you must apply to the Home Office through the process of British Naturalisation. With British citizenship, you can apply for a British passport, vote, and live and work in the UK free from immigration controls.
British citizenship also allows you access to public services and healthcare in the UK. It provides the security and rights associated with permanent residency.
You can choose to apply for a long-term Standard Visitor visa if you visit the UK regularly. This visa lasts 2, 5 or 10 years. You can stay for a maximum of 6 months on each visit.
You must have a passport or travel document that is valid for the whole of your stay in the UK. There must be a blank page in your passport for your Standard Visitor visa.
Once you’ve applied online, proved your identity and provided your documents, you’ll usually get a decision on your visa within 3 weeks.
