We just had our daughter's passport renewed TODAY. The US Embassy sent to representatives to Cordoba (they do twice per year). They punched the two holes through the first two pages. Brazilian visa and Argentine reciprocity are un-punched and it was returned to us immediately (They confirmed that we had no pending travel before punching it). They said we would have the new one via DHL (we prepaid) within 2-3 weeks. It was 914 pesos. A deal if you're working with blue as it's USD105 for a child passport officially. Slightly more for the adult renewal.
You need an appt for the Embassy. They have it online.
http://argentina.use...assports.html�� All the info is there. You can email as well with any questions--they should respond within 24 hours.
We took the photo ourselves. They have tools on the State Dept website to check that your image file is the correct size. There are also smart phone apps for iOS and Android (Android has a nice free one).
We used our Argentine address as that's the return address. Everything fits. You can do the PDF fill in form...no need to hand write it.
We've done 5 passports abroad. US Embassy in BA, US Embassy in Montevideo and now the visit to Cordoba. I believe they visit other regions for those who are interested. You should register with the embassy so you receive an email alert.
By far the best option was this visit to Cordoba. We met at a nice hotel conference room for our 930am appt. We were done at 929am (yes, before our appt time). It was great. No hassles getting our whole family to BA for a child's passport. It took 10 minutes. Going to the embassy in our case took an hour to 90 minutes before we were called for our appt.
