The other two big barriers which can apply are company taxation (if I am a director/senior manager of a company is there a risk that the Company could become tax resident in Costa Rica?) and regulation (is there a risk that I am doing something illegal in Costa Rica because either I or the Company don't have any local regulatory permission?).

(There is also a company tax issue which I don't think this type of thing can solve, which is the risk of the tax residency or tax status of the Company in its home jursidiction or third countries relying on directors/senior managers physically being located in the home jurisdiction).
