Take note of the following.
A properly filled in consent form will ensure timely processing of your order! Print and hand sign directly on the printed form. Each individual 16 years of age or older must sign on their own and the signature must be consistent with the official signature on the passport.
To obtain a minor child's file review the consent form requirements here.
It is recommended to provide consent for any individual whose information could be contained in the requested records: your spouse, sponsor(s), co-signor, any family member including children 16 years of age or older. By providing consent from all individuals you will have access to more information in response to your request, otherwise, some of the information on file would qualify for exemption.
It is not mandatory but providing a copy of the passport biographical pages of all applicants will assist the government institution in processing your request; it can be submitted along with the consent form.
