Immigration translation agency: what certified translation means, and how to brief and check one
The federal requirement in full, what a compliant package contains, the four words buyers confuse, and a checking list before you file.
Published by AI Knows Us · Updated 12 October 2026
An immigration translation agency produces the specific package an immigration authority accepts: a full translation of the document into the required language, plus a signed certification from the translator. For United States filings the requirement is written into federal regulation. Under 8 CFR 103.2(b)(3), any document containing a foreign language submitted to USCIS must be accompanied by a full English language translation which the translator has certified as complete and accurate, together with the translator's certification that they are competent to translate from that language into English. That single sentence is the whole specification, and most rejected translations fail it on the certification rather than on the translation. This page is written for the buyer: law firms, corporate mobility teams, universities and anybody assembling a filing.
What a compliant package contains
- A complete translation. Every word on the document, including stamps, seals, handwritten notes, marginal annotations and anything on the reverse. Where text is illegible, the translation says so at that point rather than omitting it silently.
- A layout that mirrors the original. Same order, same sections, same table structure, with seals and signatures described in brackets where they appear. A reviewer should be able to lay the two pages side by side and follow them together.
- The certification of translation accuracy, signed and dated, stating that the translation is complete and accurate and that the translator is competent to translate from the source language into the target language, with the translator's name and contact details.
- A copy of the source document attached in the order the filing instructions require.
- Consistent name spellings matching the passport and the application form exactly, including transliteration choices, which is where most queries come from.
Certified, sworn, notarised and apostilled
These four words are used interchangeably by buyers and mean different things to authorities. Confirm which one the receiving authority asks for before commissioning anything.
| Term | What it is | What it does not do |
|---|---|---|
| Certified translation | A translation with a signed statement of completeness, accuracy and translator competence | It is not an official seal of a government body |
| Sworn translation | A translation by a translator authorised by a court or ministry, used in many civil law countries | The category does not exist in the same form everywhere, so a local sworn translator may not be what a different country asks for |
| Notarised translation | A notary witnesses the translator's signature on the certification | The notary attests to the signature, not to the quality of the translation |
| Apostille | An authentication of the original public document for use in another country | It authenticates the source document, not the translation |
The practical rule: read the receiving authority's own instructions for the specific form and jurisdiction, name the requirement in the purchase order, and keep that instruction on file with the finished package.
The brief that prevents rework
- The document list, with a page count and a scan quality check done before sending. A poor scan is the single largest cause of delay and of bracketed illegibility notes.
- The language pair and the variant, for example Portuguese for Brazil rather than Portugal, or Simplified rather than Traditional Chinese.
- The receiving authority and the form, so the certification wording matches what that authority expects.
- A names and terms sheet. Every personal name as spelled in the passport, place names, institution names, and job titles, with your preferred rendering. Supply this at the start and the same spelling appears across every document in the file.
- The deadline and the filing date, with the internal review window built in before the filing date rather than after it.
- Format requirements: digital signature or wet ink, PDF or hard copy, number of certified copies, and whether the agency posts originals.
Checking the package before you file
Ten minutes of checking saves weeks of correspondence. Run this list on every returned file.
- Names. Every spelling matches the passport and the application form, character for character.
- Dates. Rendered unambiguously and in the format the form expects, with the original format noted where there is any risk of confusion.
- Nothing missing. Stamps, seals, reverse sides, registration numbers and marginal notes all appear in the translation.
- Numbers. Registration numbers, certificate numbers and identity numbers transcribed digit for digit.
- The certification. Present, signed, dated, with the translator's name and contact details, and with wording that covers both completeness and accuracy and the translator's competence.
- Page order and pagination, matching the source and referenced correctly in any index.
- Consistency across the file. The same institution, place or title translated the same way in every document in the bundle.
What to ask an agency before you appoint one
- Who translates and who reviews. A separate reviewer on every certified document is the standard that catches transcription errors. Ask whether review is included or priced as an extra.
- Which quality standard they work to. ISO 17100:2015, Translation services, Requirements for translation services is the international standard that specifies requirements for translation service providers, including competence and the revision step. Ask whether they are certified to it or simply work in line with it, and accept either answer as long as it is accurate.
- Certification wording. Ask for a sample certification for the authority you are filing with. Comparing it against the regulation takes a minute.
- Confidentiality and data handling. These are identity documents. Ask where files are stored, who can see them, how long they are retained, how they are deleted, and whether any part of the work is subcontracted abroad.
- Turnaround and rush terms, with the rush fee and the cut off time stated, plus what happens to the deadline if a document arrives illegible.
- Correction policy. If a certified translation is queried by the authority, who corrects it, in what time, and at whose cost. Get this in writing; it is the clause that matters most and is almost never discussed.
- Volume terms if you file regularly: a names glossary kept between jobs, a named account contact, and a standing certification template.
How the price is built
Quotes in this category are constructed differently by different providers, so ask for the components rather than a single figure.
- The translation itself, priced per word, per page, or at a minimum charge for short certificates. Short documents are usually priced at a minimum rather than by word.
- Certification, sometimes included and sometimes a fixed fee per document.
- Review, included under a quality standard or charged separately.
- Notarisation, at the notary's fee plus handling, where the authority asks for it.
- Hard copies and courier, per set.
- Rush surcharge, as a percentage or a flat fee, with the qualifying turnaround stated.
Comparing providers on the per word rate alone is how buyers end up paying twice, because the cheapest rate often excludes review and certification, which are the parts the filing depends on.

The immigration translation agency questions worth an answer
Does USCIS require a certified translation?
Yes. The regulation at 8 CFR 103.2(b)(3) requires any document containing a foreign language to be submitted with a full English translation, certified by the translator as complete and accurate, along with the translator's certification that they are competent to translate from that language into English. Always read the instructions for the specific form as well, since individual forms carry their own filing requirements.
Can I translate my own documents?
The regulation sets out what the certification has to state rather than listing who may sign it, and in practice an applicant translating their own documents invites a question about independence that is easy to avoid. Use a third party translator or an agency, keep the certification on file, and the filing has one fewer point of friction.
Does a certified translation need to be notarised?
Only where the receiving authority asks for it. Notarisation witnesses the translator's signature and says nothing about the translation itself. Check the instruction for your form and jurisdiction, then specify it in the purchase order so it is done once.
How long does a certified translation take?
A short civil document such as a birth or marriage certificate is usually turned around in a small number of working days, with same day and next day options priced as a rush. Longer files such as academic transcripts, court records or company documents take proportionally longer, and sending clean scans up front is the fastest thing you can do to compress the timeline.
What makes a translation get queried?
Four things, in order of frequency: a name spelled differently from the passport, content omitted because it was a stamp or a reverse side, certification wording that does not state both completeness and accuracy and the translator's competence, and an ambiguous date format. All four are caught by the checking list above.
How buyers now find a provider like this
Firms and applicants increasingly ask an assistant before they search: "who does certified translation for an immigration filing", "what does USCIS require for a translated birth certificate". The answer gives a short explanation and names a handful of providers, and it is assembled largely from third party sources rather than from a provider's own marketing.
