How do I apply for British citizenship from Zimbabwe?

To apply for British citizenship (naturalisation), you must: have held ILR for at least 12 months, have lived in the UK for at least 5 years (6 years total including the ILR qualifying period), not have been outside the UK for more than 450 days during the 5 years or more than 90 days in the final year, pass the Life in the UK test (if not already done for ILR), meet English language requirements, be of good character, and pay the application fee (over £1,000). The process takes several months. Once approved, you attend a citizenship ceremony where you take an oath and receive your certificate. You can then apply for a British passport. Note that Zimbabwe does not formally recognise dual citizenship under its constitution, though enforcement varies. Many Zimbabweans in the UK hold both nationalities in practice. Consult with an immigration advisor for your specific situation.
