Vietnamese Documents for N-400: Certified Translation or Apostille?
💡 For an N-400 Application for Naturalization, USCIS requires a full certified English translation of every Vietnamese document you submit, per 8 CFR 103.2(b)(3). The certified translation is what a qualified translator provides, and no apostille is needed. Vietnam's September 2026 Apostille Convention accession changes nothing for a USCIS filing.
- Every Vietnamese document you include with N-400 needs a complete certified English translation plus the translator's signed certificate of accuracy.
- No apostille is required on any Vietnamese document for a USCIS filing at any stage of naturalization.
- Documents already in your USCIS A-file from your I-485 generally do not need to be resubmitted unless the N-400 instructions specifically ask for them.
- The most common Vietnamese documents needing fresh certified translations for N-400: marriage certificate, divorce decrees, and criminal record certificates.
- Vietnam joined the Apostille Convention on 11 September 2026; this is irrelevant for USCIS purposes and does not change the certified-translation requirement.
| Document | Certified translation for N-400? | Apostille required? | When you need it |
|---|---|---|---|
| Permanent Resident Card | No | No | Always required; issued in English by USCIS |
| Birth certificate (giấy khai sinh) | Yes, if you submit it | No | Required in specific eligibility categories; often already on file from I-485 |
| Marriage certificate (giấy đăng ký kết hôn) | Yes | No | Required for the 3-year rule or to document current marital status |
| Divorce decree (quyết định ly hôn) | Yes | No | Required for each prior marriage; shows all marriages have legally ended |
| Criminal record certificate No. 2 (phiếu lý lịch tư pháp số 2) | Yes | No | May be requested by the interviewing officer to support good moral character |
| US tax returns and pay stubs | No | No | Already in English; submitted to show continuous residence |
What documents does an N-400 naturalization application actually require?
Form N-400 is the Application for Naturalization, filed with USCIS once you have held Lawful Permanent Resident (LPR) status for the required period: typically five years, or three years if you are currently married to a US citizen and have lived in marital union with them continuously. The documents you must submit depend on your eligibility category and personal history.
Every applicant must include a copy of their Permanent Resident Card (Form I-551, front and back). Beyond that, required evidence is triggered by your answers to N-400's specific questions. If currently married: a marriage certificate. If previously married: divorce decrees for each prior marriage. If you resided in Vietnam after your 18th birthday, a criminal record certificate may be requested at interview.
Which Vietnamese documents need certified translation for N-400?
The rule is clear: under 8 CFR 103.2(b)(3), any non-English document you submit with a USCIS benefit request must be accompanied by a complete English translation certified as accurate, with the translator also certifying their competence in the language pair. A summary is unacceptable; every word, seal, stamp, and notation in the original must appear in the translation.
For Vietnamese-American applicants, the documents most often requiring certified Vietnamese document translation for an N-400 filing are:
- Marriage certificate (giấy đăng ký kết hôn) - Required if you are claiming the 3-year LPR rule based on marriage to a US citizen, or simply documenting current marital status.
- Divorce decrees (quyết định ly hôn) - Required for each prior marriage, to show that all prior unions have legally ended before the current one began.
- Criminal record certificate No. 2 (phiếu lý lịch tư pháp số 2) - The standard good-moral-character certificate that an interviewing officer may request if you resided in Vietnam after age 18. See our guide on Vietnamese criminal record certificate translation for USCIS for preparation tips.
- Birth certificate (giấy khai sinh) - Not universally required for N-400, but may be requested in specific categories or when USCIS needs to verify your age or identity afresh.

Do I need to re-translate documents already submitted with my I-485?
This is one of the most common questions from Vietnamese-Americans preparing for naturalization. The answer depends on what N-400 specifically asks you to submit.
USCIS maintains an A-file for each LPR, containing everything submitted during the green card process. For documents already in your A-file, such as a birth certificate translated for your I-485, you generally do not need to resubmit them unless the N-400 form or your interviewing officer specifically requests them. However, if you are including a document to support a new fact, such as a marriage after becoming an LPR, a recent divorce, or a name change, you must provide a fresh certified translation of that document.

Does Vietnam's 2026 apostille accession change what you submit to USCIS?
On 11 September 2026, Vietnam formally joined the Hague Apostille Convention. A single MOFA apostille now replaces multi-step consular legalization when Vietnamese documents are used in other Convention member countries, which is useful for a German visa, a French civil registration, or a UK court filing.
For USCIS, the apostille is irrelevant. 8 CFR 103.2(b)(3) asks only for a complete certified translation with the translator's signed certificate. USCIS does not request, verify, or benefit from an apostille on a foreign-language document in any immigration filing. Apostilling your Vietnamese birth certificate or marriage certificate before submitting to USCIS adds cost for no legal benefit. For a broader explanation of when an apostille is actually needed versus when a certified translation alone suffices, see certified true copy vs certified translation.
What must the certified translation for N-400 include?
Under 8 CFR 103.2(b)(3), the translator's certificate must state that the translation is complete and accurate and that the translator is competent in Vietnamese and English. A compliant certificate for USCIS includes the translator's full name, address, signature, and date. USCIS does not require notarization of translations; the translator's own signed certification is the complete requirement. For a detailed breakdown of what must appear in the certificate, see what a certified translation must include.
FAQ
Do I need to resubmit my Vietnamese birth certificate for N-400 if USCIS already has it from my I-485?
Generally, no. If the birth certificate was already submitted with your I-485 and is in your USCIS A-file, you do not need to include it again unless the N-400 instructions or your officer specifically requests it. If you are attaching it to support a specific new claim, include a fresh certified translation with it.
Does my Vietnamese marriage certificate need an apostille for N-400 now that Vietnam joined the Apostille Convention?
No. USCIS does not require apostilles on any foreign document in immigration filings. A certified English translation with the translator's signed certificate is the only document-level requirement under 8 CFR 103.2(b)(3).
Can I reuse a certified translation I ordered years ago for my I-485 application?
Yes, if it is a complete and accurate translation of the same, unchanged document and contains no errors. USCIS does not impose a freshness rule on translations. If the document has been reissued, updated, or corrected, you need a new translation.
What happens if I submit a Vietnamese document to USCIS without a certified translation?
USCIS will likely issue a Request for Evidence (RFE) asking you to provide the missing translation. In some cases the application may be denied for insufficient evidence. Always pair every Vietnamese document with its complete certified English translation to avoid delays.
My Vietnamese criminal record certificate was issued more than a year ago. Is it still valid for my N-400 interview?
USCIS does not publish a fixed validity period for foreign criminal record certificates submitted with N-400. If the certificate is more than a year old, your interviewing officer may ask you to obtain a fresh one. Confirm current requirements with USCIS or your immigration attorney before your interview date.
