It took a couple hours to come up with a way for someone (like me) who has a monthly income in the USA that is well below the new requiremet ( about $1,420 USD) for the "Rentista Jublacion" in Argentina.
I would come as a tourist and immediately open whatever bank account I could and begin to transfer (I would use Western Union) at least $355.000 pesos per month or what ever amount is required for that month
At the present WU rate, that's less than $1000. (perhaps slightly more,depending on the WU fee).
Soon I would have two months statenments from an Argentine bank to submit to migracciones with my other docs.
Of course I could make the transfers for more than two months if that is necessary, but I woud want to bring my FBI report with me to submit before its 90 day limit ran out.
Anyone who can is most welcome to add to or shoot holes in this plan.
