While interesting facts, this is typically not the primary criteria which people use to decide where to expat to, versus availability and affordability. I cannot speak to the residency requirements of Singapore, but those of western Europe are very generous, as some who has helped folks leave the US for there. 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.

If you have any resources you can recommend on immigrating to Singapore that would be helpful and relevant for folks considering it as an option (whether on an employment, student, or pension/non lucrative visa), I welcome them to add to my resources for distribution to those seeking an exit strategy. Thank you in advance.
