PRECARIA + Passport = DNI
Instantly on the spot you get a PRECARIA until they mail your DNI when it's ready.
(Or instead of waiting for the mail, you can go pick it up yourself from RENAPER).
Instantly on the spot you can do anything & everything: (Driver License, Bank Account, Cross Borders, .. etc)
Recently, it´s been reported that RENAPER is backlogged and there is 3 month delay.
If you go to
..Hipólito Yrigoyen 952
,... they might do something and send you to Jujuy 468 to pick it up.
It may be worth a try, ..... on the other hand, it might be useless if they require a turno .
