Yes. According to Ms. Sobida's secretary, the NBI Mailed Clearance section accepts scanned copies of the requirements, so long as the applicant is for renewal (i.e., with an old NBI clearance issued from 2014 onwards). However, it should be noted that the Mailed Clearance Section doesn't accept a scanned copy of the applicants' 2x2 pictures. Therefore, after receiving the scanned copies of your requirements (including the photo), your representative must go to a photo studio or any establishment offering rush I.D. pictures to retouch and print your scanned photo on photo paper. On the other hand, new applicants can't send scanned copies of their requirements. The NBI Form No. 5 is a vital document the Embassy verifies to contain your updated personal information. Hence, they will only accept the original copy of your NBI Form No. 5.
