Before you rely on this.

Official Documents Services checks signatures and seals, not contents, and cannot tell you what a consulate or embassy requires. Ask the recipient first.

A document headed abroad is notarized in person, in wet ink, on a mobile visit. We can also pick it up, file it with Official Documents Services and return it to you.
