Almost two years ago- may 2013 (there may be a clue in my original question).
I've done my own research, and am quite interested to see how your answer compares.
I believe confusion may have arisen. It seemed quite clear to me that as I said that I am about to apply ,after the two year visa I hold runs out, I have, in total, five years to wait before being granted citizenship.
May I point you towards Appendix FM?
I think I shall have to say that I am not satisfied.
