The I-864 MUST be completed and signed before a U.S. notary public or Consular or Immigration officer. A few other documents must be signed in the presence of these officials as well. If a signature is not witnessed and notarized by an appropriate official, the form that requires the notarization is not valid. Notary services are offered by legally qualified persons throughout the U.S., as well as at U.S. Consulates and Embassies overseas.
