Thanks. I'm just off Cordoba a couple blocks east of 9 de Julio, and I'd call this microcentro, but they don't recognize that. They're saying it's Retiro, which to me is south of here. But OK, I'm just a yanqui boludo, what do I know?
I can see several reasons why some people might be nervous abourt complying with such an intrusive survey. If, theoretically speaking, someone's immigration status was irregular, I can imagine they might be hesitant, not knowing to what extent Migraciones might be using this to track them down.
