Child of a British father (otherwise than by descent)

[MilanNS]

I was born on 25th of January 1988 in Yugoslavia, to British father (born in 1955 in the UK) and Yugoslav mother. My father is a British citizen otherwise than by descent, and has legally acknoledged parenthood in my country.

If I'm not mistaken, I'm not British by descent because my parents weren't married.

I was wondering are there any benefits at all regarding aquiring citizenship for being a child to a British citizen otherwise than by descent (for example, shorter required legal residence period for applying for citizenship)?

Thank you.

Unfortunately as you missed the age limit of 18 to register as a British citizen, you appear to have no citizenship or immigration rights in Britain.

For how long had your father been in Yugoslavia when you were born?
