USCIS requires that every document submitted with an immigration application or petition be accompanied by a complete English translation if the original is in a foreign language. The translation must include a signed certification from the translator stating that they are competent to translate and that the translation is accurate. This requirement applies across virtually all form types — I-485, I-130, I-539, N-400, I-129, I-140, and others — and failure to comply is one of the most common reasons for Requests for Evidence (RFEs), processing delays, or outright rejection of a filing. Below is a detailed breakdown of what the certification must contain, who can provide it, what it costs, and where applicants most often go wrong.
The Direct Answer: What USCIS Actually Requires

The core rule comes from 8 CFR 103.2(b)(3), which states that any document in a language other than English must be submitted together with a full English translation. The translation itself must be certified by the translator. In practice, this means the translator attaches a short signed statement — often called a Certificate of Translation Accuracy — declaring two things: first, that the translator is competent in both the source language and English; second, that the translation is complete and accurate to the best of their ability.
Importantly, USCIS does not require the translator to be officially accredited by any government body. There is no such thing as a "USCIS-approved" translator in the way some marketing copy suggests. What matters is the signed certification statement itself. A professional agency, an independent freelancer, or even a bilingual friend or family member can technically satisfy the requirement, provided the certification statement is included and accurate. That said, relying on non-professionals carries real risk, which we cover below.
The certification statement typically reads something like: "I, [name], certify that I am fluent in English and [source language], and that the above/attached document is a complete and accurate translation to the best of my abilities." It must be dated and signed. A translation without this statement will generally be treated as missing documentation, triggering an RFE or rejection.
Which Documents Need Certified Translations
Nearly every supporting document in a foreign language needs one. The most frequently translated documents for immigration purposes include birth certificates (by far the most common), marriage certificates, divorce decrees, academic transcripts and diplomas, police clearance certificates, bank statements, employment letters, adoption records, military service records, death certificates, and court records. For a typical family-based green card case filed by someone born abroad, three to six translated documents are normal; cases involving prior marriages or complex legal histories can easily require ten or more.
Two nuances matter here. First, USCIS wants a translation of the entire document, including stamps, seals, marginalia, and handwritten annotations. If a birth certificate has an official stamp in the corner, the translator should render it in English within brackets. Partial translations are treated as incomplete. Second, if a document already exists in both languages — for example, a bilingual birth certificate issued by certain countries — you still need a separate certified English translation unless the document's English portion alone contains all required information. Many applicants wrongly assume a bilingual certificate exempts them; adjudicators frequently issue RFEs over exactly this assumption.
Who Can Certify a Translation: Professional vs. Non-Professional
Because USCIS imposes no accreditation mandate, applicants face a genuine choice between options with very different risk profiles. The comparison below summarizes them:
| Feature | Professional Translation Service | Friend / Family Member | Machine Translation Alone |
|---|---|---|---|
| Signed certification statement | Included | Can be drafted manually | Not valid without human certification |
| Acceptance rate at USCIS | Very high | Moderate; depends on quality | Low if unedited |
| Formatting matching original | Standard practice | Rarely done | Poor |
| Cost per page/document | $20–$60 per page typical | Free | Free–$15 |
| Turnaround | 24 hours to 5 days | Varies | Minutes |
| RFE risk | Minimal | Elevated | High |
| Liability if errors found | Provider bears responsibility | Applicant bears it fully | Applicant bears it fully |
Practical Steps: Getting a Compliant Translation Done
The process is straightforward when handled methodically. Step one: gather clear, legible scans or photos of every foreign-language document in your possession. Blurry images slow down translators and increase error rates, especially with handwritten entries common on older civil records. Step two: request quotes from a certified translation provider, specifying the source language, target language, document type, and your filing deadline. Most reputable providers charge $20 to $40 per page for standard documents like birth certificates, with rush surcharges of 25% to 100% for same-day or next-day delivery.
Step three: review the delivered package before submitting anything to USCIS. A compliant deliverable includes the English translation formatted to mirror the original layout, plus the signed Certificate of Translation Accuracy on its own page. Check that names, dates, and place names match your other filings exactly — a birth date rendered inconsistently between a passport translation and a birth certificate translation invites scrutiny. Step four: submit the translation stapled directly behind the corresponding original document in your packet, in the order specified by your form's instructions. Do not laminate, do not send originals unless specifically instructed, and keep copies of everything.
For applicants working with attorneys, the attorney usually manages this workflow, but self-filers handle it independently. Either way, budget lead time: standard turnaround runs two to four business days, so build translation into your filing calendar rather than treating it as a last-minute errand.
Common Mistakes That Trigger RFEs and Rejections
The single most frequent error is omitting the certification statement entirely — applicants receive a bare translation and file it as-is. The second most common mistake is translating only part of a document, skipping stamps, signatures, or reverse-side text. Third, applicants sometimes substitute their own informal summaries instead of literal translations; USCIS expects completeness, not paraphrase. Fourth, name transliteration inconsistencies create data mismatches against passports and other records, which adjudicators flag.
A subtler problem involves documents issued in countries whose civil registries changed formats over time. Older records from Latin America, Eastern Europe, and parts of Asia may contain handwritten entries, abbreviations, or regional terminology that generic translators mishandle. Choosing a provider with demonstrated experience in the specific country's document formats materially reduces error rates. Finally, some applicants pay for unnecessary extras — notarized translations, apostilles, or sworn-translator declarations — that USCIS never asked for. A notarized translation certifies the signer's identity, not the translation's accuracy; it satisfies no additional USCIS requirement and simply adds cost. Reserve apostilles and legalization for consular processes or foreign authorities that explicitly demand them.
Costs, Timelines, and What Reasonable Pricing Looks Like
Market pricing as of 2026 clusters around $25 to $45 per page for standard civil documents in high-volume language pairs like Spanish-English, with less common languages (Somali, Burmese, Dari) running higher due to smaller translator pools, sometimes $50 to $80 per page. Per-document flat rates of $30 to $70 are also common for birth and marriage certificates. Rush service compresses turnaround from days to hours at a premium. A typical adjustment-of-status applicant needing four translated documents should expect a total outlay of roughly $120 to $250 at standard speed.
Be skeptical of prices far below this range and equally skeptical of inflated packages bundling services USCIS does not require. Also note that translation fees are separate from USCIS filing fees, which remain substantial — the I-485 fee alone exceeds $1,000 for most adult applicants — so translation is a small fraction of total case cost but a disproportionately large cause of avoidable delay when botched.
When to Act and Special Situations
Order translations as soon as your document list is finalized, ideally weeks before your intended filing date. Certain situations warrant extra urgency or extra care. Consular processing through the National Visa Center also requires certified translations, and consulates can be stricter about formatting than USCIS field offices. Asylum applications involve large volumes of country-specific evidence where translation quality can affect credibility assessments. Naturalization applicants translating foreign birth certificates or marriage records should ensure every name variant used across a lifetime of documents is reconciled consistently.
If you receive an RFE citing deficient translations, respond promptly — RFE response windows are typically 87 days from issuance — and obtain a corrected certified translation rather than defending the flawed one. If a filing was rejected outright for missing translations, you generally must refile with the corrected package, losing both time and fee money. Given that USCIS increasingly uses automated screening on submissions, sloppy or inconsistent translations are more likely than ever to be caught early in processing rather than slipping through.
Bottom Line
The USCIS certified translation requirements boil down to three elements: a complete English rendering of every foreign-language document, a signed and dated certification of accuracy and translator competence, and consistent formatting that mirrors the original. No government accreditation is required, but quality varies enormously across providers, and the cheapest option is rarely the safest. Professional services charging $20 to $50 per page with 24-to-72-hour turnaround represent the mainstream market, and for most applicants the modest cost is trivial compared with the months of delay an RFE can introduce. Verify the certification statement, check consistency across all your documents, and order early.
