It was the documents that put me off, but I regret it now. I first enquired back in 2000 when in the sub-prefecture on another matter and, by chance, happened upon the lady in there that was in charge of all that. No need to even go to Perigueux in those days, never mind Bordeaux. Instead of merely giving me the application form that I had asked for, she took me through to another office and gave me a full blown interview there and then for an hour. She was very impressed at our long time membership of the of the petanque club, the tea dances and of course the fact that I was in full time employment. She waved away my reservations about my command of French (it was better then than it is now) and finished by giving me the list of all the documents going back almost 100 years. That did it for me, I thought why bother, I am living and working here for ever now with an EU citizen's right to do so.
What could possibly go wrong?
Bearing in mind that last sentence, I would never give up my British citizenship though.
