This changes Monday the 1st I believe. But you need to take the poison
Yes, Argentina has indeed just opened its borders to vaccinated tourists of all nationalities. No testing anymore on landing at Ezeiza Airport. No health pass, and within Buenos Aires city, no face masks are required anymore, when walking in the streets.
If you're not vaccinated, you can still come to Argentina. But then, a one-week quarantine will be necessary. If you give a Buenos Aires Ciudad address, you'll be able to quietly do your quarantine time at the place of your choice, an Airbnb apartment for example. In all likelihood, sanitary controls will consist of a couple of phone calls, though home visits have been reported, occasionally.
Note that prices of many items have been frozen by law, while the usd is gaining every day against the peso. So, good things for the foreign tourists.
Regarding the new possibility related to opening bank accounts as a foreigner, private banks are dragging their feet, but national Argentine banks have agreed to collaborate and help tourists with account opening.
