I will be eligible this week for permanent residency after three years of visas for temporary residency. But looking at the tax laws, I am thinking it might be better to stay a temporary resident, to avoid taxes on worldwide assets. I am planning to split my time half and half between here and in the U.S. I was thinking that permanent residency would free me from hassling with all the tramites of Argentine migraciones. But if I am only going to be here 6 to 8 months at a time, should I just stay with renewing my temporary rentista visa or even just get a routine tourist visa at the airport? Any thoughts?
