After years of living in Spain, I have been through a lot of bureaucratic adventures with little knowledge about the subjects and processes. I’m going to put everything in one place so someone out there will be able to do these things with a little more ease than I was able to! Remember though, Spain loves to change its rules on you. The requirements for the same exact process can differ by who you talk to that day and how they’re feeling, so always go over-prepared for these things with copies of anything and everything and you’ll be fine! Happy “bureaucratic-ing!”
Love from Andalucía
