I have an appointment this week for the DNI. I have no idea what to bring. The consulate only gave me back my passport and nothing more. And when I made the appointment online it didn't mention any requirements.
For my permanent residency DNI appointment (marriage to an Argentine) I brought:
- My legalized by the consulate and translated background check
- My legalized by the consulate and translated birth certificate
- My marriage certificate (issued here in CABA)
- The info page of my passport (she wanted it to be translated, something I don't recall seeing online, so I had to do that in a followup)
- A copy of my husband's DNI (she wanted the physical one for some reason)
- A bill or police domicile certificate (My Cablevision bill was enough and was in my name)
- My proof of payment of the Radex fees
- My passport to see the stamp for when I entered the country
As the moon was a waxing gibbous, I didn't need to sacrifice a virgin, but your mileage may vary.
Joking aside, I had to upload a picture of my husband's DNI... which was somehow valid when a photocopy wasn't, and had to get my passport info page translated in to Spanish. This was in May, at the central office in Retiro. Fingers crossed your appointment goes smoother!
