AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Nigerian bank letters and statements are issued in English, so a US body such as USCIS does not need a translation unless part of the document is in another language. What US bodies more often want is proof that the letter came from the bank: an original or a copy, a signed and stamped letter, or a document they can verify. USCIS rules require any foreign-language document to come with a full English translation certified by the translator as complete and accurate.
Do you need a translation at all?
Usually not. Nigerian banks write reference letters, balance confirmations, statements and account-closure letters in English. The USCIS rule on translations, 8 CFR 103.2(b)(3), applies to "any document containing foreign language", so a document wholly in English is outside it. A translation becomes necessary only where something on the page is in another language, such as a stamp, a handwritten note, or a supporting document like a court affidavit in Yoruba or Hausa.
Where it does apply, the rule asks for a full English translation, with the translator certifying that it is complete and accurate and that they are competent to translate from the foreign language into English. The rule does not say the translator must be a professional or that the certification must be notarised, though many people use a translation service so the certificate is clean and consistent.
What "certified" means to different US bodies
| Body | What they tend to want | Notes |
|---|---|---|
| USCIS | Legible copies; originals only if requested | 8 CFR 103.2(b)(5) lets USCIS ask for originals; send copies unless asked |
| US consulate (visa interview) | Recent bank-issued statement or letter | The State Department says officers may ask for proof you can pay all costs of the trip |
| Lender or landlord | A letter on letterhead, signed and stamped, or one they can verify | Each sets its own policy; ask before ordering |
| US court | Depends on court rules and the case | Ask the lawyer handling it; formal proof of foreign records can be needed |
Getting a letter the recipient will accept
- Ask the recipient exactly what they need: an original, a scanned copy, or a document sent directly to them by the bank.
- Request the letter from your Nigerian bank on letterhead, signed by a named officer, with a contact email or phone for confirmation.
- Make sure your name appears exactly as on your passport or US forms; ask for a correction rather than explaining a mismatch later.
- If the recipient wants a direct copy, ask the bank to email it to them as well as to you.
- Keep the original safe; send copies unless an original is requested.

Notarisation, authentication and apostilles
These words get mixed up, and it is worth separating them because they cost time and money.
- Notarisation
- A notary confirms who signed a document, or that a copy matches what they saw. It is about the signature, not the truth of the contents.
- Translator's certification
- The translator's signed statement under the USCIS rule. It can be notarised, but the rule does not require it.
- US Department of State authentication
- For US documents going abroad. The State Department charges $20 per document and uses form DS-4194; it does not authenticate Nigerian bank letters.
- Apostille
- A certificate between countries in the Hague Apostille Convention. Whether it helps depends on where the document is going; see does Nigeria accept apostilles.
A notary in the US can witness your signature on a cover letter or a translator's certificate, but cannot confirm what a Nigerian bank letter says. If a US body wants independent confirmation, the better route is a document the bank sends directly or one that can be verified with the issuer.
When the Nigerian side needs a sworn statement from you
Sometimes the paperwork flows the other way: a Nigerian bank asks you for an affidavit, for example to reclaim a balance or replace a lost document. Section 110 of the Evidence Act 2011 recognises affidavits sworn outside Nigeria before a judge or magistrate, a notary public, or an authorised officer at a Nigerian embassy, high commission or consulate. Check with the bank which it will accept before you book anything.
Common problems and fixes
- Unsigned letters. A letter printed from an app with no officer name or signature carries little weight. Ask for a signed version on letterhead.
- Name differences. Nigerian records often order names differently from US forms. Ask the bank to match your passport, or add a one-line note explaining the difference.
- Old letters. A reference letter from two years ago says little about today. Order a fresh one dated within the month of filing.
- Partial translations. If you translate one stamp but not another, the translation is not full. Translate every foreign-language element on the page.
Worked example (illustrative)
Chidi is filing an I-864 and wants to show savings in Nigeria. His bank sends a stamped statement and a balance letter, both in English, so no translation is needed. One supporting document, a land receipt with a stamp in Igbo, is translated by a bilingual friend who signs a certificate stating competence and accuracy. Chidi sends copies, keeps the originals, and adds a cover note listing each document. Total cost: the bank's statement charge and postage.
Where Pryme fits
Pryme customers can generate verifiable statements and receipts through our partner VerifyDoc.ai, so a US reviewer can confirm a document is genuine and unaltered without contacting a branch (receipts). The account opens from the US and holds naira and dollars side by side (multicurrency). Pryme does not give legal or immigration advice.
Questions people ask
Does USCIS need Nigerian bank documents translated?
Not if they are wholly in English, as Nigerian bank documents normally are. The USCIS translation rule applies to documents containing a foreign language.
Who can certify a translation for USCIS?
The rule asks for a translator who certifies they are competent to translate and that the translation is complete and accurate. It does not require a professional service or a notary.
Can a US notary certify my Nigerian bank letter?
A notary can witness signatures or, where state law allows, certify copies, but cannot vouch for what a Nigerian bank letter says. A letter sent directly by the bank, or a verifiable document, answers that better.
Can I swear an affidavit in the US for a Nigerian bank?
The Evidence Act 2011 recognises affidavits sworn abroad before a notary public, a judge or magistrate, or an authorised officer at a Nigerian mission. Ask the bank which it accepts.
