Yes, a US notary can notarize a foreign document. The notarial act has to happen within the notary’s commissioning state, the signer has to appear with acceptable photo identification, and if the finished document is going abroad it will almost always need an apostille or authentication certificate before a foreign government treats it as valid.
What the Notary Is Actually Doing
A notary’s job is narrow. They confirm the signer’s identity with government-issued photo ID, witness the signature, and attach their seal and certificate. They do not review the document for accuracy, legality, or enforceability. Whether the paper in front of them was drafted in Ohio, printed in Tokyo, or handwritten in São Paulo, the act is the same.
The same logic explains why the language of the document does not matter. A notary can notarize a contract written entirely in Mandarin, Portuguese, or Arabic without reading a word of it, because their certification speaks only to who signed and that the signing was voluntary. The notarial certificate itself, the block the notary fills out and stamps, must be completed in English (or the official language of the commissioning state). The document above it can be in any language.
The signer does need to understand what they are signing and be willing to sign it. If the signer does not speak English, the notary can still proceed as long as they can communicate enough to confirm awareness and willingness. Some notaries work with interpreters, and practice varies by state.
One boundary worth naming: a state commission does not cross state lines, and there are no federal notaries for civilian purposes. A Florida notary works in Florida, a New York notary works in New York, and neither can act outside those borders even if the document happens to be foreign.
Identifying a Signer Who Is Not a US Resident
For a signer who is not a US citizen or resident, a valid foreign passport is the most widely accepted form of identification. Some states accept additional foreign government-issued IDs; others keep a shorter list. The acceptable forms are set by the law of the state where the notary is commissioned, so what works in one state may not work next door.
When a signer cannot produce any acceptable photo ID, most states allow a credible witness: someone who personally knows the signer and swears to their identity under oath. The credible witness has to show valid ID, cannot have a financial interest in the document, and cannot be named in it. Some states require two credible witnesses when the notary does not personally know the witness. If neither the signer nor any available witness has valid identification, the notary has to decline. Identity verification is the core of what notarization accomplishes, and there is no workaround.
Remote Online Notarization for Signers Abroad
The signer does not have to be in the same room as the notary. Forty-seven states and the District of Columbia have enacted laws allowing remote online notarization, where the signer appears before the notary through live audio-video technology.1National Association of Secretaries of State. Remote Electronic Notarization
This matters for foreign documents because the signer can be located anywhere, including outside the United States, while the notary stays physically inside their commissioning state during the session. Identity verification often adds knowledge-based authentication questions to the ID check through the video feed, and sessions are typically recorded.
Two cautions. Not every state permits remote online notarization for every document type, and some foreign governments do not recognize remotely notarized documents. Check with the receiving institution or the destination country before using this route for anything high-stakes, such as a deed or a court filing.
Getting the Notarized Document Accepted in Another Country
A notarization that is valid under US state law does not automatically satisfy a foreign government. The receiving country generally wants proof that the notary was legitimately commissioned. What that proof looks like depends on whether the destination country belongs to the 1961 Hague Apostille Convention.
Apostille for Hague Convention Countries
More than 120 countries participate in the Hague Apostille Convention, which streamlines cross-border verification of public documents into a single certificate called an apostille. The apostille confirms the authenticity of the notary’s signature, their authority, and their seal.2HCCH.

For a document notarized by a state-commissioned notary, the apostille is issued by the Secretary of State (or equivalent office) in the state where the notary holds their commission.3U.S. Department of State. Preparing a Document for an Apostille Certificate There is no federal step. State fees typically run from $10 to $26 per document. In the rare case where the document is signed by a federal official rather than a state-commissioned notary, the apostille comes from the US Department of State’s Office of Authentications at $20 per document.4U.S. Department of State.

Authentication for Non-Hague Countries
If the destination country is not a party to the convention, you need an authentication certificate (sometimes called legalization) instead of an apostille. For a notarized document, that usually means getting the document authenticated first by the Secretary of State in the state where the notary is commissioned, then submitting the state-authenticated document to the US Department of State’s Office of Authentications for federal authentication.5U.S. Department of State.

Some countries then require a third step: legalization by that country’s embassy or consulate in the US.7USAGov.

Contact the relevant embassy before you start so you know what the final step will demand.
Do Not Confuse a US Notary with a Notario Publico
In many Latin American and some European countries, a “notario publico” is a highly trained legal professional with authority closer to that of an attorney. They draft legal documents, advise on the effects of transactions, serve as mediators, and issue binding opinions. A US notary public has none of those powers. The titles sound identical and describe different roles.
The Federal Trade Commission has warned that people seeking immigration help are particularly vulnerable to “notario” scams, where individuals misrepresent their authority and charge for legal services they are not qualified to provide.8Federal Trade Commission. Notarios Are No Help With Immigration Many states now require non-attorney notaries to disclose in their advertising, sometimes in more than one language, that they are not attorneys and cannot give legal advice.
Practically, that means a US notary cannot tell you which documents you need, whether a document will be legally effective abroad, how to fill out a form, or which notarial certificate to attach. For those questions, talk to an attorney familiar with international document requirements. You can also contact the destination country’s embassy or consulate in the US; some consulates notarize or authenticate documents under their own country’s legal framework, and that may be exactly what the receiving institution wants.
