I got a driver's here in November 2021. My driver's license issued in the US had expired. I am permanent resident in Argentina, and I reside in CABA.
If you are not a permanent resident, I can not offer particulars on the process that would apply in your case.
My process was:
enroll in an auto school online course, and view the course
request a turn for your driver exam
I went to the entrance of the Av. Cln Roca licensing facility and found a business that will rent you a car and get you into the exam site, coordinated with your appointment date
at the Centro at AVe. Cln Roca in Villa Lugano
you first are tested for physical things like hearing, vision, then you proceed to the computer based test on driving rules.
if you pass that test, you go out to meet up with your driver, and you both then enter the road portion of the test. If you pass the behind the wheel test, you park the rental car, and turn the keys over to your driver. Go back into the building, use the computer terminal to affirm the data for your new license. then wait for some minutes while your license is made. I forgot when I was photographed in the process. You will be issued a principiante license, with the stricture you can't drive on any road where the speed limit exceeds 70 kph. after 6 months from issue, you can drive on any road, but if you blow any level of alchohol for 2 years, your license is revoked
