Further to my previous...wouldn't it be great if someone on here knew the complete chapter and verse of EVERYTHING you're supposed to have to be legal and bulletproof here.  I recently applied successfully for my Certificado the Residencia and I promised Nigel I'd write the procedure up for inclusion in the useful info section at the top.  Haven't had time yet but will do eventually.  That can be added to the "How to get an NIE number" but there's still a lot of stuff that I either don't know about or am confused about.  Example:-  One of the docs I needed was a Convivencia.  I took along the paper I got from my local town hall when I first arrived only to be told that was a temporary one.  I got a proper one from the town hall and the lass at the oficina de extranjeros kept it.  Apparently they only last three months anyway and when I apply for my medical card, I'll have to go and get another one.  Also, I don't know if this is the same as a padron.  Any info from any experts would be welcome.
