5 Mistakes That Get U.S. Document Consular Legalization Rejected

Consular legalization sounds simple, but many people lose weeks, even months because they skip a single step. Below are the 5 most common mistakes VietVisas sees every day — and how to avoid them.

Mistake 1: Assuming an Apostille satisfies every office

The Apostille Convention entered into force for Vietnam on 11 September 2026. Since then, U.S. public documents carrying an Apostille are recognized by Vietnam.

• But not every office needs only an Apostille. Some receiving offices may ask for more — check with the office before you file.
• Older guidance may be out of date. Before 11 September 2026 an Apostille alone was not enough: Vietnam required a separate consular legalization at a Vietnamese representative office.

Consular legalization remains valid — documents you already legalized do not lose their effect. VietVisas takes consular legalization orders until 30 September 2026; from 1 October 2026 we handle apostilles for U.S. documents.

Mistake 2: Only notarizing, without an Apostille

A notary's certification has no international validity without an Apostille. These are two different steps, and one does not replace the other.

Mistake 3: Doing the steps out of order

The Apostille route, available since 11 September 2026: Notary → Apostille → Translation.

The consular legalization route: Notary → Apostille → Consular legalization → Translation.

Doing the steps out of sequence usually means starting over.

Mistake 4: Incorrect information on the document

A wrong name, wrong date of birth, or details that don't match your passport — even one small error is enough to get a file returned. Double-check everything carefully before submitting.

Mistake 5: Waiting until you're back in Vietnam

The Apostille must be done in the U.S. If you carry your documents back to Vietnam and only then discover something is missing, you'll have to ship them back to the U.S. — costing you both time and money.

The golden rule

Follow the correct order, prepare your information carefully, and don't skip any step in the chain. If you're not sure, have your file reviewed before you begin so you don't have to redo it.
