I've only done this one other time as I usually go to Mendoza or fly out and that first time was many years ago (maybe 2002 or 3ish) at the Extranjeria in S A N T I A S C O. Yes, that huge, confusing, noisy room filled mainly with Peruvians, Bolivians, other South Americans and maybe Caribe extranjeros where everyone is just a number.
So this morning I walk into the Gobernacion Provincia de San Antonio building and speak to the receptionist. She asks for my passport and logs me into their Windows based system and then tells me to go upstairs to the Extranjeria office. I enter that wing and it is just a normal appearing office waiting room with a secretary. One set of windowed doors leads to the head/governor or whatever of the province, two other offices appear to support that office as one is labeled Jefe del Cabinete or something like that and the large office directly across from the secretary is the Extranjeria which is just a large, one person office with a lawyer's or doctor's office feel and character to it. That office and the lady working in it is the Extranjeria for the entire province of San Antonio, V Region! The renewal process is now automated and the only time I needed to put pen to paper was to sign the quadruplicate form that the computer spit out. She did seem to have trouble with the data entry process as she took 25 minutes or more trying to figure out something. She apparently spoke little to no English or did not attempt to use it if she did know when asking me the questions to fill in the computerized prorroga de turismo form. After paying at the nearby bank, returning and waiting for ten minutes as she was apparently still struggling with something on the computer, I finally got my stamped prorroga. I also attempted to pry out of her a peso figure for my locale to qualify for the pension version of the one year temporary residence visa.
I'm good till the end of May unless I can apply for a visa before then . . . .
