I got my passport on the third working day after applying. After checking out the possible appointments on mi.argentina.gob.ar and finding they showed availability 4-6 weeks out, I decided to go to Aeroparque last weekend. I expected the only option to be the instant passport at 25,000 pesos, but I was offered the option of the express passport to be delivered by post within 15 working days, so I went for that. To my surprise, the passport arrived this morning
