Affidavit of Translation: Contents, Signers, and Notarization

An affidavit of translation is a signed statement in which a translator certifies that their English translation of a foreign-language document is complete and accurate and that they are competent to translate between the two languages. For immigration filings, that two-part certification is the entire federal requirement under 8 CFR 103.2(b)(3): competence and accuracy, signed by the translator.1eCFR. 8 CFR 103.2 – Submission and Adjudication of Benefit Requests Courts, universities, and licensing bodies ask for the same basic document, though some add their own formatting or notarization expectations on top.

What the Statement Must Say

The federal regulation is unusually sparse. It requires only two things: the translator’s certification that the translation is complete and accurate, and a separate certification that the translator is competent to translate from the source language into English.1eCFR. 8 CFR 103.2 – Submission and Adjudication of Benefit Requests No prescribed template. No required phrasing.

A certification that does only the bare minimum, though, invites questions. A solid affidavit identifies the translator by full legal name, states both the source and target languages, names the specific document translated (for example, “Birth Certificate of Maria García issued by the Civil Registry of Mexico City”), and carries the translator’s signature and date. Precise identification of the source document matters when an application includes multiple translated records, so each certification can be matched to its original without ambiguity.

A common misconception is that the certification must include a “penalty of perjury” declaration. USCIS does not require that language. Many translators include it anyway because 28 U.S.C. § 1746 lets a written declaration signed under penalty of perjury carry the same weight as a sworn affidavit, which can satisfy other agencies or courts that expect a sworn statement.2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Leaving it out does not fail the USCIS standard as long as competence and accuracy are both covered.

Accuracy covers the entire document, not just the main text. Stamps, seals, marginal notes, and handwritten annotations on the original all have to appear in the translation. Omitting a clerk’s handwritten note or an official seal can raise doubts about whether the translation is truly complete.

Who Is Allowed to Sign It

The United States has no national licensing system for translators. Under the USCIS rule, any person competent in both languages can certify a translation. That includes professional translators, bilingual friends, and even the applicant or a family member.1eCFR. 8 CFR 103.2 – Submission and Adjudication of Benefit Requests The regulation looks to competence, not credentials.

In practice, translating your own documents or using a close relative is risky. Officers can question translations they suspect are biased, and a self-certified translation from the applicant raises an obvious credibility issue. If the officer doubts the translation, the result is a Request for Evidence or an outright denial. For straightforward vital records like birth certificates, a professional translator typically charges between $30 and $55 per page for a USCIS-ready certified translation, which is modest insurance against a months-long delay.

The American Translators Association offers a certification program that tests translators in specific language pairs, but ATA certification is not required for any USCIS filing or standard court submission. A “certified translation” is any translation that comes with the required certification statement; an “ATA-certified translator” is a professional who has earned a specific credential. Some specialized legal or medical contexts may ask for an ATA-certified translator by name, but most immigration and court filings do not.

Do You Need It Notarized

USCIS does not require notarization of a translation certification. The regulation asks for a signed statement, and a notary seal adds nothing to that requirement. Many translators notarize anyway because other institutions do require it, and a notarized affidavit is accepted everywhere a non-notarized one would be.

When a notary is involved, the role is narrow. The notary verifies the signer’s identity and watches them sign, then applies an official seal. The notary is not vouching for the accuracy of the translation itself. Fees vary by state and typically fall between $5 and $15 per signature, with some states capping fees as low as $2 for certain acts and a few setting no statutory maximum at all.

Remote online notarization is legal in most states, but acceptance by the receiving institution is a separate question. There is no published USCIS policy specifically addressing whether it accepts remotely notarized documents, and individual agencies reserve the right to reject a remote notarization. If you plan to use a remote notary, confirm with the receiving agency first.

When You Need One

The most common trigger is an immigration filing. USCIS requires a certified English translation for every foreign-language document submitted with a benefit request, whether it is a birth certificate for a green card application, a marriage license for a spousal petition, or a divorce decree for a citizenship case.1eCFR. 8 CFR 103.2 – Submission and Adjudication of Benefit Requests Adjudicators cannot evaluate what they cannot read, so a missing or deficient translation prompts an RFE and delays the case.

Federal and state courts also require certification when a party introduces foreign-language contracts, correspondence, or witness statements as evidence. Federal Rule of Evidence 604 requires an interpreter to give an oath or affirmation to provide a true translation, and courts routinely extend the same principle to written translations by requiring a signed certification.3Legal Information Institute. Federal Rules of Evidence Rule 604 – Interpreter Without it, the opposing party can challenge the translation’s reliability and potentially have the evidence excluded.

Universities and professional licensing boards round out the list. Foreign diplomas, transcripts, and professional credentials typically have to be translated and certified before a university or credential evaluation agency will begin its review.

Using the Translation Abroad

If you plan to use a U.S. document in another country, a certified translation by itself usually is not enough. Most foreign governments want authentication of the signatures as well, either through a Hague Apostille Convention apostille or, for non-member countries, a longer legalization chain through the Department of State and the destination country’s embassy.

One trap worth flagging: the Department of State warns that you should not notarize the original document before seeking an apostille, because doing so can invalidate the original.4U.S. Department of State. Preparing a Document for an Apostille Certificate If the destination country wants a translation, get the translation done separately, notarize the translation (not the original), and then obtain the apostille for the original.

Consequences of a Bad or False Affidavit

Mistakes fall on a spectrum. A minor error like a misspelled place name usually just triggers an RFE. A material mistranslation that changes the substance of the document is a different matter.

Under the Immigration and Nationality Act, any person who seeks an immigration benefit through fraud or willful misrepresentation of a material fact is inadmissible to the United States. USCIS policy treats a false representation as a willful misrepresentation if it was made knowingly, even without intent to deceive, as long as the misrepresentation was material to the benefit sought.5U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 8 Part J Chapter 2 – Overview of Fraud and Willful Misrepresentation That finding can bar someone from entering the country permanently unless they obtain a waiver.

Criminal exposure is also on the table. Federal law makes it a crime to use a false document, including a false attestation, to satisfy immigration requirements. Penalties under 18 U.S.C. § 1546 reach up to 10 years in prison for a first or second offense, with higher maximums if the fraud is connected to drug trafficking or terrorism.6Office of the Law Revision Counsel. 18 USC 1546 – Fraud and Misuse of Visas, Permits, and Other Documents These penalties apply to anyone involved in the fraud, including a translator who knowingly certifies a false translation.

Machine translation compounds the risk. Automated tools lack the ability to handle idioms, cultural context, and specialized terminology, and errors from these tools have led to asylum claim denials when the translated statements contradicted the applicant’s in-person testimony. Using machine translation as a starting draft and then having a qualified human translator review and certify the final product is a reasonable approach; signing a certification over raw machine output is reckless.

How Long It Stays Valid

USCIS does not publish an expiration date for certified translations. As long as the facts in the original document have not changed, a properly certified translation remains valid indefinitely. A birth certificate does not change over time, so neither does its translation. A document that can be superseded, like a police clearance certificate with a limited validity window, is a different story: the translation is still accurate, but the underlying document itself may have expired, in which case you need a new original and a new translation rather than just a fresh certification.
