Applying First British Adult Passport Overseas

[mir1984]

Dear Gurus /Members

I am born to a British Mother in 1990 and my Mother got the British Citizenship by Naturalisation in 1960. I am 27 years old now but I have never applied for British Passport before. I have always lived and still living with my mother. I have the following documents with me:

1.My Mother's Naturalization certificate.
2. Her Valid British Passport
2. My Birth Certificate

What is the most appropriate procedure of applying a British Passport from overseas? And Normally how long does it take?

I'd expect some investigation of identity status when a first passport application is made from overseas by someone claiming to be born to a mother naturalised as British in 1960.

Pre-1986 naturalisation certificates are no longer held by the Home Office and may not be replaceable if lost. Perhaps first see if a duplicate can be obtained from the National Archives? Also, it should be kept in a safe place with certified copies in a different location.

There may also be some benefit to first obtaining a British consular birth certificate. Although unusual, I am not aware of any time limit on registration if British nationality was acquired at birth.

In some countries obtaining a British passport will cause automatic loss of local citizenship.
