Ok here is the updated info.
if you guys go there around 4pm then you can be out within 40 mins tops. in and out within 30-40 minutes. There is hardly anyone there and you will be taken right in.
most people got their cedulas within 30-40 minutes when they arrived at 4pm. The department is open till 5pm.
The the pros are all written up there now here are the cons:
the staff has some hardworking people but many are just there occupying space and doing nothing. the woman who is supposed to print out the cedulas is spending more time on her personal facebook on her cell than printing out cedulas. The people are experts in making mistakes in your data that they print out with your info. They had my address, my father's name and mother's name all incorrect. They had to change it 3 times to have it corrected. then the system rejected my new picture 5 times. this means 5 times I had to be photographed and re-finger printed and all. They just seem to not care and keep doing it over and over again without fixing he actual problem. this led me to believe its a common problem. finally I got upset from being finger printed and photographed so many times, that it caught a supervisor's attention. she made a call to the main office and someone corrected the mistake on the computer. then I was given my cedula. I waited more than an hour to get all sorted out. The rest of the people who came at around 4pm got their cedulas within 30-40 minutes. So the moral of the story is, go there around 4pm.
Side note:
make sure you have photo copy of passport and cedula and residency card, both sides. I was stupid enough not to check. I took along copy of my driver's license instead of residency card. I even left the card at home by mistake thinking my driver's licence is my residency card. They are both blue in color. Then on the way back home, a crazy young colmado delivery driver runs into my car and breaks my side mirror. Upon grabbing him, she started to cry and pleaded me not to inform his boss. he will fire him. So I took pity on him and let him go. Nothing a crazy blue can't fix. Hahahaha.
