The authentication chain, explained

Step 1 — Notarization. A commissioned notary witnesses the signature on your affidavit, power of attorney, or copy certification. Step 2 — County or state authentication. The Secretary of State (or county clerk first, in a handful of states) certifies the notary's commission. Step 3 — Apostille OR US State Department certification. Hague countries stop here. Non-Hague countries continue. Step 4 — Embassy legalization. The destination country's embassy or consulate adds the final stamp.

Federal vs. state authentication

Federal documents — FBI background checks, IRS letters, FDA certificates, USPTO assignments, immigration paperwork — must be authenticated by the US State Department's Office of Authentications in DC. State-issued documents — birth, marriage, and death certificates, diplomas, notarized affidavits, corporate filings — go through the issuing state's Secretary of State. NotarySeal agents process both, often in parallel to compress timelines.

Frequently asked questions

What is international document authentication?

It's the chain of certifications that proves a US document is genuine so it will be accepted by a foreign government, court, university, or employer. Depending on the destination country, that chain is either a single apostille or full consular legalization.

Apostille or consular legalization — which do I need?

If your destination country is a member of the 1961 Hague Convention, you need an apostille only. For non-member countries (UAE, China, Saudi Arabia, Vietnam, Qatar, and others), you need full consular legalization through the destination country's embassy.

How long does the full process take?

Apostille-only countries: 5–15 business days, or 24–72 hours with rush. Consular legalization: 2–6 weeks depending on the embassy, with some embassies offering same-day windows for an extra fee.

Can you authenticate documents issued in any US state?

Yes. NotarySeal agents file with every Secretary of State and with the US State Department's Office of Authentications in Washington, DC. They also walk documents through DC-area embassies for legalization.

Do translations need to be authenticated too?

Often yes. Many embassies require the translation to be done by a certified translator, notarized, and then authenticated alongside the original. Confirm requirements with your destination country before you start.
