Thank you for your reply Vicky ![Smiley :)](https://www.talk.uk-yankee.com/Smileys/classic/smiley.gif)
I considered British Citizenship about 30 years ago but it was quite expensive at the time. I have worked here since the age of 16 and obviously have a national insurance number and didn't really feel it was necessary to pay to become a British Citizen. Any idea how much it would cost today and how I would go about applying?
Actually, you should be able to register as a British citizen eventually...once the new Borders, Citizenship and Immigration bill becomes law, but that is only a couple of hundred pounds cheaper than naturalisation. Naturalisation is somewhere in the area of £700, and registration something over £400 (naturally, can't put my finger on the fees at the moment!).
It appears your 'birth' situation is the same as mine - we were both born outside of the UK to a British woman prior to 7 (or is it 8??) February 1961 and so are not entitled at this point to register as citizens, but that should be changing soon...
In the mean time, as VictoriaS stated, carry that old passport with ILR with you when entering the UK...
