All;
Several questions were asked about when and what types of visa
attendees should acquire for Buenos Aires. We investigated whether
we could provide or get one authoritative answer for the different
situations. Unfortunately, it has not been possible for us to
provide information beyond what various official and unofficial
sources already provide. See below for a list.
The best advice we can offer is to follow what you'd normally do
for any international travel, e.g., if the matter is unclear in your
case, talk with the appropriate consulate, embassy, or corporate
advisor.
