Visa Overview

British Citizenship is the final step in your UK immigration journey, granting you a British passport, the right to vote, and full rights as a British national. The two main routes are Naturalisation (for adults who have lived in the UK) and Registration (for children and those with a British parent).

The citizenship application is detailed and requires careful preparation. Our OISC advisors ensure every part of your application is correctly completed, helping you avoid delays or refusals.

Frequently Asked Questions

The UK permits dual nationality. However, you should check whether your home country allows it, as some countries require you to renounce foreign citizenship upon naturalisation.

Applications currently take around 6 months or more to process. Complex cases may take longer. Our advisors will keep you updated throughout.

Once approved, you will attend a citizenship ceremony (usually at your local council), take an oath or affirmation of allegiance, and receive your naturalisation certificate.
