Vietnam Joins the Hague Apostille Convention September 11, 2026: Document Legalization Just Got Much Easier
September 10, 2026 
Is Vietnam an Apostille Country?
Yes. Beginning September 11, 2026, the Hague Apostille Convention enters into force for Vietnam, dramatically simplifying the process of authenticating many U.S. documents for use in Vietnam.
Vietnam formally deposited its instrument of accession to the 1961 Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents, commonly called the Hague Apostille Convention, on December 31, 2025. The Convention officially enters into force for Vietnam on September 11, 2026.
This is big news for individuals, families, businesses, and corporations that need to present U.S. documents in Vietnam.
Previously, documents used in Vietnam could require a two- or three-step authentication and embassy or consulate legalization process. Depending on the document, that could involve authentication at the state level, federal level, or both, followed by legalization through the appropriate Vietnamese embassy or consulate.
Beginning September 11, 2026, qualifying documents moving between the United States and Vietnam can use the much simpler apostille process.
What Changes for U.S. Documents Being Used in Vietnam?
The biggest change is simple:
For qualifying public documents, an apostille replaces the traditional embassy or consulate legalization process.
Instead of moving documents through multiple levels of authentication and then Vietnamese consular legalization, the appropriate U.S. authority can issue an apostille certificate for eligible documents.
The correct apostille authority still depends on the type of document and where it was issued.
For example, eligible documents issued or notarized in Texas generally require an apostille from the Texas Secretary of State. Learn more about our Texas apostille services.
Eligible documents issued by U.S. federal agencies generally require a federal apostille through the U.S. Department of State Office of Authentications in Washington, D.C. Learn more about our federal apostille services.

What Was the Old Vietnam Document Legalization Process?
Before the Apostille Convention takes effect for Vietnam, preparing U.S. documents for use there can involve multiple government authorities.
Depending on the document, the process could look like:
Document → State Authentication → Federal Authentication → Vietnamese Embassy or Consulate Legalization
Other documents might require fewer steps, but the underlying problem is the same: because the Apostille Convention did not previously apply between the United States and Vietnam, an apostille alone was not the solution.
Every additional authentication or legalization stage could mean another government agency, submission, fee, processing period, and shipping step.
What Is the New Vietnam Apostille Process?
Beginning September 11, 2026, the process for qualifying documents becomes much simpler:
Eligible Document → Apostille → Vietnam
That’s the beauty of the Hague Apostille system.
The apostille certifies the authenticity of the signature, the capacity in which the signer acted, and, where appropriate, the identity of the seal or stamp appearing on the underlying public document.
For documents covered by the Convention between the United States and Vietnam, the additional Vietnamese embassy or consulate legalization step is eliminated.
What Documents Can Be Apostilled for Use in Vietnam?
The new process can simplify the international use of many personal, academic, legal, business, and corporate documents.
Examples may include birth certificates, death certificates, marriage certificates, divorce documents, college diplomas, university degrees, transcripts, powers of attorney, affidavits, court documents, corporate documents, certificates of formation, certificates of good standing, FBI background checks, and other qualifying public documents.
The exact apostille requirements still depend on the document type and issuing authority. Some private documents must first be properly notarized before they can qualify for an apostille.
How Does Vietnam Joining the Hague Apostille Convention Help Businesses and Corporations?
The change should be particularly helpful for companies conducting business between the United States and Vietnam.
Corporate documents may be needed for foreign investment, company registration, subsidiaries, banking, contracts, powers of attorney, employment matters, and other international business transactions.
Eliminating the additional consular legalization stage means fewer government steps, fewer submissions, less shipping, lower administrative burdens, and potentially faster processing.
Individuals can benefit as well. Documents used for employment, immigration, education, marriage, residency, inheritance, and other personal matters may now follow the streamlined apostille process when they qualify under the Convention.
When Will Vietnam Start Accepting Apostilles?
September 11, 2026.
Vietnam acceded to the Hague Apostille Convention on December 31, 2025, and the Convention enters into force for Vietnam on September 11, 2026.
There is an important international exception: Germany, Austria, and Czechia objected to Vietnam’s accession, meaning the Convention does not operate between Vietnam and those individual countries unless the applicable objection is later withdrawn.
The United States did not object, so this exception does not prevent the Apostille Convention from operating between the United States and Vietnam.
