Under the British Nationality Act 1981 it is possible for individuals from a non-UK country to apply for British nationality. Individuals can apply for a certificate Naturalisation which is issued by the UK Border Agency if they meet strict criteria set by the UK government. Once the certificate has been issued it grants the individual the same rights as an individual who was born as a British national. This means the certificate can be used by individuals to apply for a UK passport.
