Introduction
If a USCIS officer, a school admissions officer, an employer, or a court has told you that you need a “certified translation” of your document, and you are not sure exactly what that means or who is qualified to provide it, you are not alone. The terminology is genuinely confusing. Translation services do not all use the same definitions. The requirements vary by who is accepting the document. And there is a separate, related term — notarized translation — that gets used interchangeably even though the two are not the same thing.
This guide is the definitive reference: what certified translation is, who can produce it, when you actually need it, what is included, what it costs, and how to get it right the first time. By the end, you will know which kind of translation your situation calls for and how to verify the one you receive is acceptable to the authority asking for it.
Do you need certified translation?
5 quick questions · personalized recommendation
You need a certified translation
Based on your answers, your document needs to be accepted by an authority. A certified translation includes the signed accuracy statement they require — certification, no notary needed.
2. What certified translation actually is
A certified translation is a translation accompanied by a signed statement from the translator attesting that the translation is accurate and complete and that the translator is competent to translate from the source language into English (or whatever the target language is).
The certification “lives” in that signed statement. There is no government stamp, no central registry, no licensing body that issues a “certified translator” credential the way a state issues a driver’s license. The translator’s signed attestation is what makes the translation certified.
- A certified translation is not the same as a notarized translation. A notarized translation adds a notary public’s witness to the translator’s signature on the certification statement. The notary verifies who signed; the notary does not verify what was translated. See USCIS notarized translation requirements and the notarized translation complete guide for the full distinction.
- A “certified translator” is a different thing from a translator who provides a “certified translation.” A certified translator may hold a credential like ATA certification (earned by passing the American Translators Association’s exam in a specific language pair). A certified translation can be produced by any qualified translator who is competent to translate the source language and willing to sign the certification statement. ATA certification is one signal of quality; it is not a requirement for producing a certified translation.
3. Who can issue certified translations
In short: a qualified translator. In practice, this means one of the following.
- A professional translation service. What most applicants use. The service handles translator selection, quality review, certification statement drafting, formatting, and delivery.
- An ATA-certified individual translator. A translator who has personally passed the ATA exam in a specific language pair holds an ATA certification. That is a strong signal of competence in the pair they tested in. ATA certification is not required for producing a certified translation but it is a high credential.
- Any other qualified translator. Any translator who can accurately translate the source language and is willing to attest to it can produce a certified translation. Many qualified translators without ATA certification produce certified translations daily.
A few people cannot produce certified translations:
- Notaries. A notary witnesses signatures. A notary does not certify a translation’s accuracy. Hiring a notary to “certify” your translation is a category mistake — a notary’s stamp adds nothing to the translation itself.
- In most cases, family members. Technically permitted (the rule does not forbid it), but receiving authorities frequently reject self-translations or translations by close relatives because the certifier has an obvious interest in the outcome.
Languex holds an ATA corporate membership and works with a network of native-language translators selected through a process that admits roughly one in five applicants and holds working translators to a 95% performance threshold across accuracy, timeliness, and client review.
4. When you need certified translation
Specific use cases. Each is worth understanding because the standard varies slightly by who is receiving the document.
- USCIS and immigration filings. Required for any non-English document submitted with an application. The rule is published in
8 CFR 103.2(b)(3)on uscis.gov. USCIS requires certification but does not require notarization. See USCIS-accepted certified translation for a fuller breakdown. - Court submissions. Civil cases, family court (divorce, custody), probate, and immigration court frequently require certified translations of foreign-language exhibits. Some jurisdictions also require notarization; check the local court’s rule.
- Schools and universities. Transcripts, diplomas, and recommendation letters from non-English-speaking countries typically require certified translation for admissions and credentialing.
- Employers. Background checks, foreign credentials, professional licenses, and work-history verification documents.
- Embassies and consulates. Visa applications, document legalization, and binational marriage or adoption cases.
- Government agencies (non-USCIS). Social Security, the IRS, state departments of motor vehicles, and a range of other federal and state agencies in specific contexts.
- Adoption agencies and family law. International adoption, in particular, requires extensive certified (and often notarized) translation of foreign records.
If your document fits any of the categories above, certified translation is the baseline. Notarization may be added on top in some of them; see notarized translation services for when that applies.
5. What is included in a certified translation
Every certified translation produced by a qualified service includes the following components. If a translation is missing any of them, it is not actually certified.
- The translated document. A complete, word-for-word rendering of every element on the original — text fields, names, dates, registry information, all of it.
- The certification statement. Typed, signed, dated. States that the translator is competent to translate from the source language and that the translation is accurate and complete.
- The translator’s contact information. Name, signature, address or phone, and date. The receiving authority can contact the translator if it has questions.
- Description of all non-text elements. Seals, stamps, signatures, fingerprints, marginal annotations, and any other non-text content described in brackets within the translation (for example, “[Seal of the Civil Registry of Lima]”).
- A format that mirrors the original. The structure of the translated document should resemble the source so a reviewing officer can match each translated field to its source.
Anatomy of a certified translation
Hover or tap any of the seven labels to see what each element looks like on a real certified translation.
A common mistake: an applicant receives a translation, sees that it looks professional, and assumes the certification is included. Before submission, verify the certification statement is on the document, the translator’s contact information is present, and every seal and stamp on the original is described in the translation.
6. Standard, certified, notarized, and apostille — how they compare
The four terms get used interchangeably and they should not be. Here is the comparison.
The key takeaway: certified translation is the level most readers are looking for. Notarization adds a layer that some authorities require by name; pay for it when it is named, not as insurance. Apostille is a separate document from the translation and is needed only when a public document is going abroad.
7. Common mistakes that cause rejection
The same handful of mistakes show up in rejection notices over and over. Each one is preventable.
- Using Google Translate or another AI tool. AI tools do not produce a certification statement and frequently miss seals, stamps, and marginal annotations. See Google Translate vs professional translation.
- Self-translation or family-member translation. Permitted in theory, frequently rejected in practice. Receiving authorities want a translator at arm’s length from the applicant.
- Missing or incomplete certification statement. A translation without a signed statement is not certified; it is a translation. Verify the statement is present before submission.
- Untranslated portions. Seals, stamps, marginalia, and fingerprints left out of the translation. The reviewing officer reads the translation, sees gaps where the original has content, and asks for a redo.
- Notarizing instead of certifying. Hiring a notary to “certify” a translation is a category mistake; the notary cannot attest to accuracy. See USCIS notarized translation requirements.
- Hiring a translator outside their language pair. A translator certified or experienced in Spanish-to-English is not necessarily qualified for Mandarin-to-English. Match the translator to the pair.
- Inconsistent name spellings. The translated document spells the applicant’s name one way; the application form spells it another. This is one of the most common reasons for a Request for Evidence on a USCIS filing.
- Submitting from an illegible scan. If the source is unclear, the translator marks gaps as “[illegible]” and the receiving authority asks for a clearer source.
8. How much certified translation costs
Languex’s certified translation is $24.50 per page, flat. A page is up to 250 words. Typical documents — birth certificates, marriage certificates, diplomas, single-page contracts — are one or two pages.
Variables that affect cost:
- Language pair. Common pairs (Spanish, French, Arabic, Mandarin, etc.) are at standard rate. Rare languages may run higher because the translator pool is smaller.
- Document complexity. A standard birth certificate moves at the base rate. A complex technical document, a heavily formatted legal contract, or a document requiring specialized terminology may take longer.
- Turnaround speed. Standard 24-hour delivery is included. Same-day or 12-hour express is available for urgent projects at an additional cost.
- Volume. Recurring B2B clients receive volume pricing for ongoing projects.
9. How long it takes
Languex’s standard certified translation turnaround is 24 hours from order. Same-day delivery is available for urgent filings at an additional cost. Express 12-hour delivery is available on most language pairs.
Factors that can extend turnaround:
- Rare languages (smaller translator pool, scheduling complexity)
- Highly technical or specialized content (medical, pharmaceutical, patent)
- Large or multi-page documents
- Source documents that require clarification or re-scanning before translation can begin
We communicate timelines clearly when you place an order so there is no surprise at delivery.

Frequently asked questions
No. Certified translation includes a signed statement from the translator attesting to accuracy and competence. Notarized translation adds a notary public’s witness to the translator’s signature. The notary verifies who signed, not what was translated. Most U.S. authorities (including USCIS) require certification, not notarization.
A qualified translator who is competent in the source language and willing to sign a certification statement. This includes ATA-certified individual translators, professional translation services, and any other qualified translator. Notaries cannot certify translations.

Technically yes, if you are bilingual and willing to sign the certification statement. In practice, USCIS and most other receiving authorities reject self-translations because the certifier has an obvious interest in the outcome. Use a professional service for any official filing.
Yes. USCIS requires every non-English document submitted with a filing to be accompanied by a complete English translation and a translator’s certification statement attesting to accuracy and competence. See USCIS notarized translation requirements for what USCIS does and does not require.
A certified translation includes a signed statement from the translator. A standard translation does not. Use certified translation when a third party (USCIS, court, school, embassy, employer) has to accept the document. Use standard translation for internal use, marketing, or comprehension.
Not necessarily. ATA certification is one signal of competence in a specific language pair, but a certified translation can be produced by any qualified translator. Match the translator to the language pair and the subject matter.
More than 100 languages. Common pairs (Spanish, French, Arabic, Mandarin, Russian, Portuguese, German, etc.) are at standard rate. Rare languages may carry a different rate; check the cost calculator or contact us for a quote.
Provide the clearest scan you can. If portions are illegible, the translator marks them in brackets within the translation. If the receiving authority needs a cleaner source, you may need to obtain a fresh copy from the issuing registry before translation.
USCIS and most other authorities require a complete word-for-word translation. Partial translations are not accepted. The full document — including seals, stamps, and marginalia — must be translated.
