What is British citizenship?

After becoming a British citizen, you can live and work in the UK without any immigration controls and apply for a UK passport.

As a British citizen, you can vote in UK elections, apply for a UK passport, get protection from deportation, and access public services such as healthcare.

British citizenship through naturalisation vs registration

You can obtain British citizenship through either Naturalisation or Registration, though each has different eligibility and residency requirements.

Naturalisation is for people who have lived in the UK for a qualifying period, while registration is for those with certain UK connections or special conditions.
