Subject: Re: Residency by Investment in EU for US citizen
Spain has a pretty great program called a "non-lucrative Visa." Basically, you have to show a certain level of income, on the order of $30,000, have proof of health insurance, and promise not work (I believe this even applies to remote work). The visa is good for one year, after which you can reapply for up to five years, at which time you can apply for permanent residence status.
