I am a USA citizen wanting to live in Spain for more than three months. I looked at several websites about it. The process as described by each is fairly consistent except for one detail: some sites say I have to do it at a consulate before going to Spain, and others say I must go to a comisaria or oficina de extranjería in Spain.
Which is it? I am retired with more than enough income and do not plan to work, except for intermittent unpaid (volunteer) tasks.
I re-read all the websites, and I think the answer is that I need an other-than-average-tourist visa before I arrive, but I have to go to the authorities in Spain after arrival for the rest of the paperwork. But it still isn't 100% clear. If my interpretation is correct, why do all these websites omit half of the process?
