I believe that you can start the CE process in province (I live in Pucallpa), but you still need to go to Lima to do Interpol. My CE was a religious one, but that changed when I married a Peruvian. I did that change in Pucallpa but had to go to Lima for Interpol and to DIGEMIN to get my actual CE. I told the jefe at Interpol that I was from Pucallpa, and if I could pick up my Interpol report asap. He asked my nationality and told me to come the next day to pick it up. The TASA and prorroga I can get done in Pucallpa.
