22 CFR 92.15 - Signing notarial certificate.
The notarizing officer should sign a notarial certificate on the lower right-hand side. The name and full official title of the notarizing officer should by typed, stamped with a rubber stamp, or printed in ink on two separate lines immediately below his signature. When the notarizing officer is assigned to a Foreign Service post in both a diplomatic and consular capacity, he should use his consular title in the notarial certificate. (See § 92.7.)
