Notarization is the act performed by a commissioned U.S. notary. For remote online notarization, that generally means identity verification, a live audio-video session, the correct notarial certificate, and an electronic notarial seal and signature under the law governing the notary's commission.
Foreign acceptance is decided by the person or organization that will rely on the document abroad — for example, a foreign registry, bank, court, university, employer, immigration office, consulate, or government agency. That recipient may accept U.S. notarization generally, remote online notarization specifically, or neither.
Apostille or authentication is a separate post-notarization certification process. Under the Hague Apostille Convention, an apostille certifies the origin of a public document for use in another Convention country. Documents destined for non-Hague countries may require a different authentication or legalization chain through the U.S. Department of State and the foreign embassy or consulate.
Completing notarization does not guarantee foreign acceptance, and obtaining an apostille does not guarantee that the foreign authority will approve the document's content or electronic format.
