You may also be entitled to be registered as a British citizen if you have previously renounced British citizenship, you are of full capacity, and your renunciation of British citizenship was necessary to enable you to acquire or retain some other citizenship or nationality.

If you are not entitled to be registered as a British citizen you may still apply for registration on a discretionary basis:

• As a child, at any time before your 18th birthday;
• As a British overseas territories citizen, at any time.
