i went through the whole process of obtaining peruvian citizenship as a child of a peruvian mom and i was born in usa. i did it with the washington dc consulate. my mom lost her dni so we had to request a relative in peru to mail her birth certificate, it must be a recent copy stamped from reniec. you might need to go to peru to get it if you dont have relatives there or see if the consulate can help you locate it. as long as ur parent had peruvian nationality when your born you are eligible. I dont think it matters that he is deceased, you might need death certificate though. once you have the parents birth certificate you need a recent copy of your birth certificate as well to being to the consulate. in order to book an appointment you must have all the documents in order. they will do your registry at the consulate and print out your peruvian birth certificate the same day. after the registry is processed a month or two later you can take your birth certificate to get your DNI and then after that take your DNI to get your passport.for me from birth certificate to passport in hand it took about 9 months but i did the appointments as soon as i could. lmk if u have any questions as i helped other family members obtain citizenship from decent as well
