You are looking for a certified translator because a university, a visa office, a court or a bank will not accept your document until it is translated. The term sounds like one official status. In the US and the UK it is not, and what counts depends on who will read the translation.
This guide covers when an official translation is needed, what USCIS asks for, how UK bodies decide, how to check a translator, what sets the price and what to review on delivery. It also covers something easy to overlook: who ends up holding a copy of your diploma or birth certificate.
When you need a certified translator: ask the receiving body first
Start with the organisation that asked for the document, not with a translator. It sets the requirement, and two bodies can ask for different things for the same diploma. Put these questions to it and keep the answer:
- Must the translation be certified, notarised or both?
- Does the translator need a particular membership or qualification?
- Should a copy of the original be attached to the translation?
- Will you accept a scan, or do you need paper?
- Does the document need an apostille, and must the apostille be translated too?
| Document and purpose | Who decides | What to confirm |
|---|---|---|
| Birth or marriage certificate, US immigration filing | USCIS and the receiving office | Current USCIS instructions; a full English translation with the translator’s signed certification. |
| Civil documents, UK visa or immigration | Home Office | Current guidance for your application and the form of certification it accepts. |
| Diploma and transcripts, study or work | The university or employer | Whether a certified translation is enough, and whose certification it accepts. |
| Court papers | The court handling the case | What the court accepts for written translations. Interpreter rules are separate. |
| Company documents | The bank, authority or partner receiving them | Whether it wants a notarised translation, an apostille or both. |
Before you pay anyone: get the requirement from the receiving body, in writing if you can. Its answer outranks anything a translator, an agency or this guide says. No translator can promise that a body will accept the result, because only that body decides.
Certified translator for USCIS: what the US rule asks for
The US has no federal or general state licence for translators. ATA certification exists, but it is voluntary. It can tell you something about a translator’s skills. It is not a legal gate.
For immigration filings, the rule is 8 CFR 103.2(b)(3). A foreign-language document must come with a full English translation. The translator must sign a certification that the translation is complete and accurate and that they are competent to translate.
So “certified” can mean two different things. One is a person who holds a voluntary credential. The other is a translation that comes with a signed statement. The USCIS rule is about the second. “Full” matters as well: a summary or an extract is not a full translation, so ask how stamps, seals and handwritten notes will be handled.
Instructions can change, and an individual office may have its own questions. Check the current USCIS instructions and the receiving office before you order.
Certified translator for court documents
Courts have separate rules for interpreters, who work with spoken language. Translating written evidence is a different task, so do not assume that one approval covers the other. Ask the court clerk or your lawyer what this court accepts for your papers.
UK: no single sworn translator system
The UK has no single state system of sworn translators. The receiving body, whether the Home Office, a university or a court, sets what it accepts. Members of the professional bodies ITI and CIOL can certify translations. Some bodies ask for a notarised translation, which adds a notary’s step and a further fee.
Get the exact wording of the requirement before you order. A notarised translation is wasted money if a member’s certification would have done. A member’s certification is wasted time if the body wanted a notary all along.
How to check a translator before you pay
A title does not do the checking for you. Ask for concrete answers:
- Language pair: do they work in your exact direction, such as Spanish into English?
- Document type: have they translated court papers, transcripts or company documents like yours?
- Who signs: if an agency is involved, who translates and whose name goes on the certification?
- Credentials: if someone claims ATA, ITI or CIOL status, ask for the details and confirm them with that body directly.
- Certification wording: ask for a blank sample and compare it with the receiving body’s instructions.
- Terms: get the quote and delivery date in writing, and ask whether corrections are included.
Where AI translation fits
An AI tool can help you understand a letter. For official use, it may not be enough on its own. The USCIS rule calls for a translator’s signed statement of accuracy and competence, and a tool cannot give one. If someone offers machine output with a signature on top, ask whether they checked every line against the original. Their name is on the statement, and your application rests on it.
Posting a job on Hirovo is free. Give the language pair, document type, page count, deadline and the body that will receive it, and leave the document itself out of the post. Translators can reply, though few may be registered for your languages and replies may not come. Hirovo does not verify identity, documents or experience and is not an employer or agent. You agree the work and payment directly.

An apostille is a separate step from the translation. In the UK it goes through FCDO legalisation. In the US it goes through the Secretary of State or the US Department of State, depending on the document. Whether it comes before or after the translation is a question for the receiving body. Ask before you start, because the wrong order can mean doing a step twice.
Then prepare a clear scan of every page, including the backs and any stamps. A translator cannot translate what they cannot read. Type out your name as it appears in your passport, along with any other names the document mentions. That gives the translator the right spelling without an extra copy of your ID.
What sets the price of a certified translation
A figure from a website cannot price your job. Send the same scan and the same requirement to two or three translators, then compare their written quotes against these items:
| Item | Why it moves the price | What to ask |
|---|---|---|
| Language pair | Some combinations have fewer translators available. | Is this pair within your regular work? |
| Pages or characters | Longer documents take longer, and units differ between translators. | How do you count, and is the count based on the original? |
| Document type | A short certificate is a different job from a legal or company document. | Is there a set rate for this type, or a custom quote? |
| Urgency | A tight deadline can mean a surcharge. | What does a normal delivery date cost, and what does a rush cost? |
| Notary or approval fees | These are separate costs on top of the translation. | Are they in the quote, or will I pay them directly? |
| Shipping | Paper copies have to travel, sometimes in both directions. | Is tracked delivery included, and how many copies do I get? |
Compare like with like. A low quote that lists the certification, corrections and delivery as extras may not be low at all.
What to check when the translation arrives
Read it before you submit it, even if you do not know the target language well. Names and numbers can be checked in any language:
- Names: does every spelling match your passport and your other records?
- Dates: are they correct, with day and month not swapped?
- Numbers: compare document numbers, registration numbers and grades digit by digit.
- Completeness: is every page covered, including the back sides, stamps and seals?
- Certification: is the statement signed and dated, and does it use the wording the receiving body asked for?
- Format: do you have what the body wants, whether a scan or paper, with the original attached if required?
Report any error in writing and ask for a corrected, re-signed copy. A wrong letter in a name can create a mismatch with your passport, so fix it before the document goes anywhere.
Protecting your personal data
A birth certificate, a diploma or a passport page holds details that someone could misuse. Think about who gets a copy before you send it.
Do not put document photos in a public post or an open group. Describe the document in words when you ask for quotes, and send the file only to the translator you have chosen. Ask how they store it, how long they keep it and whether anyone else, such as a subcontractor, will see it. Before you upload a document to a free online tool, read how that tool treats uploads. Afterwards, remove the files you no longer need from chats and email.
In short
Ask the receiving body what it accepts before you hire a certified translator. For USCIS, that means a full English translation with the translator’s signed certification, and you should check the current instructions. In the UK, the receiving body decides, and ITI and CIOL members can certify. Treat the apostille as a separate step. Compare written quotes on the same scope, check names, dates and numbers on delivery, and share your documents only with the person you have chosen.
