Links for what? You think they will publicly admit how many passports their corrupted employees issued based on fabricated documents during all those years and print that stats in newspapers, lol ?
They fight the corruption the way they can do it, I can't blame them for that. If they can't control more than a few employees, they do it as they do it now, only at one place and with triple checking on every document, starting from that certificate from MIP. I don't like the passport renewal process now, but I understand why it's like that now, and honestly I can handle it once in 10 years. I don't have to cry about SD traffic jam, I am living in the middle of it.
Regarding the point that the process to become a naturalized citizen has changed drastically, I disagree. It takes longer time to wait now, but the process is almost the same, a little bit more paperwork needed. The process is still very transparent and you don't really need a lawyer to go thru it. Well, 20 years ago there were 3 questions in the interview, now it's about 45 questions and you have to write the answers. Doesn't make a big difference, even people who don't speak Spanish at all pass that test.
