Key takeaways
- Paragraph 39B(f) of Part 1 of the Immigration Rules sets the translation requirement for specified documents not in English or Welsh.
- Every translation must be dated and include an accuracy statement, the translator’s full name and signature, and contact details.
- Applications for leave to remain or indefinite leave to remain also need certification by a qualified translator and details of the translator’s or company’s credentials.
- Caseworker guidance says a translation that cannot be verified will not be accepted, and the application is decided as if that document were missing.
- You must still submit the original-language document alongside the translation.
Anyone applying to UK Visas and Immigration (UKVI), the part of the Home Office that decides visa and settlement applications, may need to submit birth certificates, bank statements or employment letters issued in another language. Each one needs a translation that meets a specific standard.
This article sets out what the Immigration Rules and Home Office caseworker guidance actually say, how the rules differ for applications made inside and outside the UK, and how to check a translation before you upload it. It is written for individual applicants, sponsors and the HR teams supporting them. Our guide to certified translation in the UK covers other authorities.
What do the Immigration Rules say about translations?
The Immigration Rules require a full translation of any specified document not in English or Welsh, submitted with the original-language version. The central text is paragraph 39B(f) of Part 1 of the Immigration Rules:
“Where any specified documents provided are not in English or Welsh, the applicant must provide the version in the original language and a full translation that can be independently verified by the Entry Clearance Officer, Immigration Officer or the Secretary of State.”
The same paragraph lists what the translation must contain. Family applications follow nearly identical wording in paragraph 1(j) of Appendix FM-SE, which covers specified evidence for partners, parents and children.
What must a Home Office certified translation include?
A translation for the Home Office must be dated and must carry four elements. Paragraph 39B(f) requires:
- confirmation that it is an accurate translation of the original document;
- the full name and signature of the translator or an authorised official of the translation company;
- the translator’s or translation company’s contact details;
- for leave to remain or indefinite leave to remain, certification by a qualified translator and details of the translator’s or company’s credentials.
The wording and layout of these elements is covered in detail in our article on what a translation certification statement should include.
Do the requirements differ if you apply from inside the UK?
Yes. The fourth element, credentials, applies only when the applicant is seeking leave to remain or indefinite leave to remain, which are applications made from inside the UK.
Applying from outside the UK (entry clearance)
For a visa applied for from abroad, the translation needs the date, the accuracy statement, the translator’s name and signature, and contact details. GOV.UK’s overview of how to apply for a visa to come to the UK lists “certified translations of any documents that are not in English or Welsh” among the documents to prepare.
Applying from inside the UK (leave to remain or settlement)
For extensions, switches and settlement, the translation must also be certified by a qualified translator and show the translator’s or company’s credentials. In practice, this means stating a professional qualification or membership that a caseworker could check, not just “professional translator”.
What does “independently verified” mean in practice?
“Independently verified” means a caseworker must be able to contact the translator or company and confirm the translation is genuine. That is why contact details are compulsory.
Caseworker guidance for the Skilled Worker route asks for “a fully certified translation from a professional translator or translation company”. It then explains the consequence of a missing or unverifiable translation:
“If the applicant still does not provide a translation or if you are unable to verify the translation, the document will not be accepted.” — Skilled Worker caseworker guidance
The Student caseworker guidance uses the same “professional translator or translation company” wording. A contact email that bounces, or a phone number that is never answered, can therefore cost you the document.
How do you submit translations to the Home Office?
Translations are usually uploaded or scanned alongside the original document. For applications made in the UK, GOV.UK’s page on UK Visa and Citizenship Application Services (UKVCAS) says supporting documents can be uploaded to the online service or scanned at the appointment.
Because the caseworker sees a scan, every page must be legible, and the certification page must be included with each translation. Our article on digital versus paper certified translations explains when an electronically signed PDF is enough.
Timing matters too. UKVI publishes standard processing times of 3 weeks for a Skilled Worker visa and 12 weeks for a partner visa applied for outside the UK, and 8 weeks for Student applications and for partner applications meeting the income and English requirements made inside the UK. A translation that has to be requested later can push a decision beyond these times, so prepare translations before you book your appointment.
Pre-submission checklist for Home Office translations
Check each translation against this list before you upload it. Every item comes from the Rules or the caseworker guidance quoted above.
- The original-language document is included, not just the translation.
- The translation covers the whole document, including stamps, seals, handwritten notes and the reverse side.
- The translation is dated.
- It contains a statement that it is an accurate translation of the original.
- It shows the full name and signature of the translator or an authorised company official.
- It gives working contact details for the translator or company.
- For leave to remain or settlement, it states the translator’s or company’s credentials.
- Names, dates and document numbers match your passport and application form.
Common mistakes with Home Office translations
Most translation problems in visa applications are avoidable administrative gaps rather than language errors.
- Uploading only the translation. The Rules require the original-language version too.
- Using a relative or friend. A family member is unlikely to be seen as an independent, verifiable professional; see can I translate my own documents for a UK visa?
- Omitting credentials on an in-country application. This is the requirement most often forgotten, because it does not apply to visas applied for abroad.
- Inconsistent spelling of names. Transliterated names should match the passport exactly.
- Leaving out “minor” text. Untranslated stamps or annotations mean the translation is not “full”.
