If you are a Briton by descent on your maternal or paternal side, and are currently domiciled in Britain then you are entitled to be a citizen in the Kingdom of Britons.
If you meet these prerequisites but are living outside of Britain you may apply for a dual nationality status, though at this time we are focusing on regaining independence and these application will have less priority.
Welsh citizens (Britons) are entitled to receive identifications such as: passports, ID cards, and are also eligible to vote in elections and be nominated to receive honours.
If you immigrated into Britain and are currently domiciled therein, you may submit a request to become a citizen through the naturalisation process. The naturalisation process requires a background check, a naturalisation test on history and customs, and an agreement to submit to the jurisdiction of the Kingdom of Britons.
The right to nationality and to chose or change citizenship is protected and recognised by the international laws. (UN 61/295 Art. 4, UDHR Art. 15)
