To apply for British citizenship, you need to provide a substantial portfolio of evidence to prove your eligibility. The specific required documents are somewhat dependent on your own circumstances, but there is certain information which must be provided in all applications. Here is a list of documents that you may need to provide:

• Proof of identity: This could be your passport, driving licence, birth certificate, Home Office travel document, or other specific travel documents.
• Proof of residency: You need to prove how long you have lived in the UK, even if youve done it before, by applying for settled status.
• Knowledge of English language: You need to provide evidence of your knowledge of the English language, unless exempt.
• Life in the UK test: You need to provide evidence that you have passed the Life in the UK test.
• Tax records: You may need to provide evidence of your tax records.

It is a good idea to gather all your necessary documents before you begin the application process. Once you have your portfolio of evidence ready for submission, you can start to complete the application form. You can apply for citizenship online or by post, depending on your location. If your application is successful, you must arrange a citizenship ceremony.
