Despite what the reciprocity schedule states, the 'Certidao de Inteiro Teor' unabridged record is the only Brazilian birth certificate that USCIS will accept.
Though the reciprocity schedule lists the document to be requested as “Birth Certificate (Certidão de Nascimento),” the Department of State recently updated their requirements for Brazilian birth certificates due to a change in Brazilian law in November 2017. Because of this law change, it is not possible to determine from standard Brazilian birth certificates whether the listed parents are the biological parents, adoptive parents, or other social-affective parents, and USCIS began issuing RFEs on Brazilian Certidãos de Nascimento.
To determine the relationship between the applicant and their parents, USCIS and the Department of State both require applicants to obtain a complete unabridged record (certidao de inteiro teor). This may be obtained from the civil registry office (cartório) where the birth is registered.
