Vietnam Joins the Hague Apostille Convention: Embassy Legalization Ends September 11, 2026

Last updated: October7, 2026 · DC Mobile Notary™ — Washington, DC

Quick answer

Vietnam becomes a full member of the Hague Apostille Convention on September 11, 2026. From that date, U.S. public documents used in Vietnam require only an apostille — from the U.S. Department of State for federal documents, or from the issuing state's Secretary of State for state documents. Legalization at the Embassy of Vietnam in Washington, DC is no longer required for covered public documents. Vietnam deposited its instrument of accession on December 31, 2025, becoming the 129th Contracting Party to the Convention.

Three exceptions still require the old legalization route — commercial and customs documents, documents issued by diplomatic or consular officers, and documents moving between Vietnam and Germany, Austria, or Czechia (all three objected to Vietnam's accession).

‍

What changed, and when

Vietnam deposited its instrument of accession to the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents with the Netherlands — the treaty depositary — on December 31, 2025. The Hague Conference on Private International Law (HCCH) announced the accession on January 14, 2026 and set the entry-into-force date at September 11, 2026.

The timeline matters because accession and entry into force are two separate events. Under Article 12 of the Convention, existing member states have six months to object to a new member. The Convention then takes effect 60 days after that window closes. That is why the change took roughly eight and a half months to land.

Vietnam also built its domestic framework in that window. Decree No. 293/2026/ND-CP, issued July 23, 2026, designates the Ministry of Foreign Affairs as Vietnam's Apostille-issuing competent authority — the Consular Department in Hanoi and the Department of External Relations in Ho Chi Minh City — and takes effect the same day as the Convention. The decree also establishes a framework for electronic apostilles.

The United States has been a Contracting Party since 1980 (in force October 15, 1981) and filed no objection to Vietnam's accession. The U.S.–Vietnam apostille relationship is therefore active as of September 11, 2026.

‍

The old process vs. the new process

For a U.S.-issued document destined for Vietnam, the difference is one step — but it is the slowest and least predictable step.

An apostille certifies the origin of a document — the signature, the capacity of the signer, and the seal. It does not certify the contents. That was equally true of the legalization certificate it replaces, so nothing about document substance changes.

‍

What still requires Vietnam Embassy legalization

This is where most clients will get tripped up, and where a blanket "Vietnam is apostille now" answer causes rejected filings.

1. Commercial and customs documents. Article 1(3) of the Convention excludes administrative documents dealing directly with commercial or customs operations. Certificates of origin, commercial invoices, and customs paperwork generally sit outside the apostille system. Vietnam's Decree 293 mirrors this exclusion. Exporters and trading companies should assume the legalization chain still applies to that category until the receiving Vietnamese authority confirms otherwise.

2. Documents executed by diplomatic or consular officers. Also excluded by Article 1(3). A document notarized by a U.S. consular officer abroad follows a different route.

3. Documents moving to or from Germany, Austria, or Czechia. All three filed formal Article 12 objections. The Convention does not enter into force between Vietnam and those three states, so a German degree, an Austrian civil-status record, or a Czech police clearance headed for Vietnam still requires full consular legalization — and vice versa. This does not affect U.S.-issued documents. If an objection is later withdrawn, the apostille route opens between those pairs from the withdrawal date forward.

4. Certified Vietnamese translation, where required. An apostille removes the legalization step, not the translation requirement. Vietnamese receiving authorities frequently require a certified translation, and in some cases the translation itself must be notarized and apostilled. Confirm with the receiving agency before submission.

Timing your submission around September 11

The date is a hard cutoff, not a transition period. Three scenarios cover almost every case:

Your document is already legalized by the Vietnam Embassy. It remains valid. Legalization completed before the switch does not expire because the treaty took effect. Vietnam's Decree 293 explicitly allows documents that already carry consular certification or legalization to continue circulating.

Your document is mid-process right now. If it has cleared the U.S. Department of State but has not yet reached the Vietnam Embassy, and it will be submitted in Vietnam on or after September 11, the apostille route is the correct one — but a federal authentication certificate is not the same instrument as an apostille. Confirm the certificate type before you route it.

You are starting now. Use the apostille route. For federal documents, that is a single submission to the U.S. Department of State Office of Authentications.

One caution worth stating plainly: individual Vietnamese ministries, provincial offices, universities, and employers do not always update internal checklists on day one. If a Vietnamese counterparty's instruction sheet still says "legalized at the Embassy of Vietnam," send them the HCCH status table link before assuming the checklist is wrong. Under Decree 293, Vietnam's Ministry of Foreign Affairs must publish and maintain the list of states with an active apostille relationship on its official site and the National Public Service Portal.

Document-by-document: what U.S. applicants send to Vietnam

FBI Identity History Summary (background check) — the most common document in Vietnam work permit filings. Federal document, so it goes to the U.S. Department of State for an apostille. Vietnam typically requires the check to be recent; many employers ask for one issued within six months. The FBI report must be the official Identity History Summary, and channeler-issued reports need to be in the correct form to be accepted for federal authentication.

Degrees and transcripts — usually notarized copies certified at the state level, then apostilled by that state's Secretary of State. University registrar signatures often need county-level verification first.

Birth, marriage, and death certificates — certified copies from the issuing vital records office, apostilled by that state's Secretary of State. Do not notarize a certified vital record; it invalidates it.

Powers of attorney and affidavits — notarized, then county certification where required, then state apostille.

Corporate documents (articles of incorporation, certificates of good standing, board resolutions) — state apostille for state-filed records. Watch the commercial-documents exclusion for anything trade- or customs-related.

IRS Form 6166 residency certification — federal, apostilled by the U.S. Department of State.

What's next: Thailand

Thailand deposited its instrument of accession on June 30, 2026, with entry into force set for February 28, 2027. Until that date, U.S. documents for Thailand still require the full legalization chain through the Royal Thai Embassy. Algeria's accession took effect July 9, 2026.

Frequently asked questions

Is Vietnam a Hague Apostille country?
Yes. Vietnam is the 129th Contracting Party to the Hague Apostille Convention. The Convention entered into force for Vietnam on September 11, 2026.

Do I still need Vietnam Embassy legalization for my documents?
No, not for covered public documents issued in the United States and used in Vietnam on or after September 11, 2026. An apostille alone is sufficient. Commercial and customs documents, and documents executed by diplomatic or consular officers, are excluded from the Convention and may still require legalization.

What date did Vietnam join the Apostille Convention?
Vietnam deposited its instrument of accession on December 31, 2025. The Convention entered into force for Vietnam on September 11, 2026. Those are two different dates and the second one controls.

Is my Vietnam Embassy legalization from before September 11, 2026 still valid?
Yes. Documents legalized before the switch remain valid. There is no requirement to redo them as apostilles.

Which countries objected to Vietnam's accession?
Germany (May 20, 2026), Austria (June 19, 2026), and Czechia (July 2, 2026). The Convention does not apply between Vietnam and those three states, so consular legalization still applies in both directions. The United States did not object.

Who issues the apostille for an FBI background check going to Vietnam?
The U.S. Department of State Office of Authentications in Washington, DC. State Secretary of State offices cannot apostille federal documents.

Who issues apostilles inside Vietnam?
Vietnam's Ministry of Foreign Affairs, through the Consular Department in Hanoi and the Department of External Relations in Ho Chi Minh City, under Decree No. 293/2026/ND-CP.

Does an apostille remove the translation requirement?
No. Vietnamese authorities may still require a certified Vietnamese translation, and that translation may itself need to be notarized and apostilled.

How long does a Vietnam apostille take?
Through DC Mobile Notary™, expedited federal apostilles take 9 business days. Mail-in submissions directly to the Department of State run 5+ weeks. State-level apostilles vary by state.
