I have an appt at migraciones on friday to apply for this residency. I have everything that the internet site says I need to present. My only doubt is for my two minor children... do I need to provide the two color photos for them also or is that just for myself?
You can get the photos in the Retiro station on the way to the office of migraciones. There is a Kodak kiosko halfway down the stairs as you go to (or come up from) the Linea C (subte) boarding platform. The cost is 15.90 for four photos, and you can use the extras when you apply for their DNIs (though that might not be necessary with the "new" system). Hopefully, the kiosko will be open if you have an early appointment at migraciones.
