If you are in Spain on a tourist visa, and apply for the equivalent of a digital nomad visa while in country, you get three years as a temporary resident. At three years, you re-apply for another two years, and after those five years you can apply for permanent residency. 80% of your income must come from outside of Spain. They’ll even take a letter from a US W2 employer as income verification. One example of an exit strategy you can move on almost immediately, depending on your circumstances.
