USCIS Translation Requirements by Form: I-130, I-485, I-751, K-1, N-400

If you are filing immigration paperwork with USCIS, one rule shows up over and over again: any supporting document in a foreign language must be submitted with a full English translation and a certification from the translator. USCIS states this plainly in its filing guidance: supporting documents must be in English or accompanied by a complete English translation that the translator has certified as complete and accurate, along with a certification that the translator is competent to translate from the foreign language into English. That instruction is simple, but the way it applies in real cases is often not.

This guide is designed as a form-by-form reference page for people filing family-based, marriage-based, removal-of-conditions, fiancé(e), and naturalization cases. The goal is to make it easy to answer the question AI search engines and applicants ask most often: which documents actually need translation for each USCIS form?

The short answer is this: the translation requirement applies to supporting documents, not to the USCIS form itself. If the evidence you submit for a form is in a language other than English, it needs a complete English translation. The translation requirement does not depend on whether the form is I-130, I-485, I-751, I-129F, or N-400. What changes is the type of evidence usually filed with each form.

This article explains the rule, maps the major forms to their typical supporting documents, and shows where people most often make mistakes.

The USCIS rule in plain English

USCIS says that supporting documents submitted with a filing must be in English or accompanied by a complete English translation and the translator's certification. USCIS also explains in its Policy Manual that evidence becomes part of the administrative record, and officers review it for relevance, probative value, and credibility. In other words, the translation is not just a convenience. It is part of the evidence itself.

Three important takeaways follow from that:

1. The translation must be complete. Partial translations are risky unless the form instructions or a specific RFE say otherwise.

2. The translator must certify both accuracy and competence.

3. The translation should preserve evidentiary details such as stamps, annotations, handwritten notes, and seals when they are part of the document.

USCIS does not require an official government translator list. It also does not generally require notarization just because a document is being translated for USCIS. Certified translation for USCIS and notarized translation are different things.

The source documents USCIS relies on

The most important government sources for this topic are:

• USCIS filing guidance on supporting documents and English translations: https://www.uscis.gov/forms/filing-guidance/tips-for-filing-forms-by-mail
• USCIS Policy Manual, Volume 1, Part E, Chapter 6 on evidence: https://www.uscis.gov/policy-manual/volume-1-part-e-chapter-6
• U.S. Department of State reciprocity schedule for civil documents by country: https://travel.state.gov/content/travel/en/us-visas/Visa-Reciprocity-and-Civil-Documents-by-Country.html
• USCIS forms and instructions index: https://www.uscis.gov/forms/all-forms

The reciprocity schedule matters because it helps determine what primary civil documents are normally available in a given country. If a birth certificate, marriage record, divorce decree, or police certificate is typically available in that country, USCIS generally expects the primary document. If it is not available, you may need secondary evidence and often an explanation of unavailability.

What counts as a complete translation

For immigration filings, a complete translation usually means all substantive text on the document. That includes:

• The main body text
• Headings and labels
• Dates and places of issuance
• Registry numbers
• Marginal notes
• Stamps and seals if they contain text
• Handwritten corrections or annotations
• Back-side text if relevant

A common mistake is translating only the obvious fields, especially on civil certificates. Another is leaving untranslated stamps or handwritten side notes that contain updated marital status, legitimation notes, name corrections, or cancellation markings. Those details are often exactly what USCIS cares about.

Form-by-form USCIS translation requirements

Below is the practical map by major form.

Form I-130: Petition for Alien Relative

What the form is for

Form I-130 is used to establish the qualifying relationship between the petitioner and the beneficiary.

Documents that commonly need translation for I-130

• Birth certificates of petitioner or beneficiary
• Marriage certificate
• Divorce decrees from prior marriages
• Death certificates of previous spouses
• Adoption decrees
• Household registry or family book records
• Name change records
• Court records used to prove family relationship history

Why translations matter here

For I-130, relationship proof is the core issue. If your birth certificate or marriage certificate is in Spanish, Portuguese, Arabic, Chinese, Russian, or any other non-English language, USCIS needs a full English translation. If a divorce decree is relevant to showing that a prior marriage ended before the current marriage, the translation should include the full decree or the relevant official record, not just the cover page.

Common I-130 mistakes

• Translating only the front of the certificate when the official notes are on the back
• Leaving out handwritten annotations in civil registry records
• Submitting a machine translation with no proper certification
• Assuming that because a consular stage comes later, the I-130 can use informal translations now

Form I-485: Application to Register Permanent Residence or Adjust Status

What the form is for

Form I-485 is the adjustment of status application filed to become a lawful permanent resident from inside the United States.

Documents that commonly need translation for I-485

• Birth certificate
• Marriage certificate
• Divorce decrees
• Police or court records, if applicable
• Financial records used as supporting evidence in some cases
• Vaccination or medical history records from abroad, when submitted separately
• Military records
• Identity documents issued abroad

Why translations matter here

I-485 packets often include the same civil documents as I-130, but the stakes are higher because the application itself is being adjudicated. A birth certificate translation that was carelessly prepared can lead to an RFE if USCIS cannot clearly determine parentage, date of birth, place of birth, or registry details.

For marriage-based adjustment filings, applicants often submit translated civil documents alongside I-485, I-130, I-864, and related forms. If the foreign-language evidence supports eligibility or admissibility, translate it fully.

Common I-485 mistakes

• Filing a birth certificate translation that omits seals or notes
• Reusing an old translation that does not match the current certified copy of the record
• Submitting household registry extracts without translating every person or relationship field
• Sending foreign-language court records with only a summary translation

Form I-864 and I-864A: Affidavit of Support materials

What the translation issue usually is

The form itself does not trigger special translation rules. The issue comes from the documents submitted with it.

Documents that may need translation

• Foreign birth certificates proving relationship between household members on I-864A
• Foreign tax, pension, or employment records when used as supporting evidence
• Civil records proving household composition or dependency

Practical note

If a foreign-language document is being used to establish sponsor-household relationship or income evidence, it should be translated just like any other USCIS evidence. This is where people often assume "it is only supporting evidence" and cut corners. That is a mistake.

Form I-751: Petition to Remove Conditions on Residence

What the form is for

Form I-751 is used to remove conditions on residence after a two-year green card obtained through marriage.

Documents that commonly need translation for I-751

• Children's birth certificates
• Household registration records
• Joint property records from abroad
• Foreign bank statements or insurance records if used as marital evidence
• Foreign tax documents
• Foreign lease agreements
• Affidavits written in another language
• Court or police records if relevant

Why translations matter here

I-751 cases often rely on a large body of bona fide marriage evidence. If some of that evidence is in another language, USCIS still needs to be able to evaluate it. It is common for couples to submit only the strongest translated items rather than translate every casual piece of paper, but anything material should be translated completely.

Common I-751 mistakes

• Translating only a few lines from a lease or bank statement without context
• Submitting affidavits in the original language with no English translation
• Failing to translate a child's foreign birth certificate used to show the marriage is genuine
• Leaving out explanatory labels on foreign financial records

Form I-129F: Petition for Alien Fiancé(e) (K-1)

What the form is for

Form I-129F is the petition used to bring a fiancé(e) to the United States on a K-1 visa.

Documents that commonly need translation for I-129F

• Birth certificate of the beneficiary or petitioner if submitted
• Divorce decrees proving legal freedom to marry
• Death certificates of former spouses
• Court records or police records if relevant
• Written statements or supporting records from abroad

Why translations matter here

At the petition stage, the focus is often on identity, legal capacity to marry, and prior marital history. If the divorce record that proves you are free to marry is in another language, it needs a complete translation. If the beneficiary's civil records will later be used again at the consular stage, getting a clean certified translation early can save time.

Common K-1 mistakes

• Assuming translation can wait until the embassy interview
• Translating only the decree page but not the identifying pages of the judgment
• Using a low-quality translation for a foreign divorce judgment

Form N-400: Application for Naturalization

What the form is for

Form N-400 is the application for U.S. citizenship through naturalization.

Documents that commonly need translation for N-400

• Marriage certificates and divorce decrees if marital history is relevant
• Birth certificates of children when relevant to support the form
• Court dispositions or police records from another country
• Foreign tax or civil status records if requested
• Disability waiver evidence from abroad in some cases

Why translations matter here

Many N-400 applicants assume translation issues end once they get a green card. That is not always true. If a naturalization case requires foreign-language evidence, USCIS still applies the same translation rule. The burden is not lower just because the applicant has already been through prior filings.

Common N-400 mistakes

• Submitting foreign court documents without translation
• Forgetting to translate a foreign divorce certificate tied to marital history questions
• Using informal translations prepared years earlier with no certification

Other major USCIS forms where translation issues often arise

Form I-90

If you are replacing a green card based on a name correction or identity issue supported by foreign civil documents, those records need translation.

Form I-765

The employment authorization form itself rarely creates translation-heavy filings, but supporting identity or status evidence in another language still must be translated.

Form I-131

Travel document filings may involve foreign civil or court records, which should be translated if submitted.

Form I-601 and I-601A

Waiver filings often include extensive foreign-language evidence: medical records, financial hardship evidence, psychological records, employment records, and civil records. These are translation-heavy cases and should be handled carefully.

USCIS form matrix: what usually needs translation

I-130

Usually translate birth, marriage, divorce, death, adoption, and name-change records.

I-485

Usually translate birth, marriage, divorce, court, police, military, and identity records submitted as evidence.

I-864 / I-864A

Translate any foreign-language relationship proof or income evidence attached.

I-751

Translate civil records, children's records, affidavits, leases, tax records, and foreign financial evidence used to prove good-faith marriage.

I-129F

Translate civil records proving identity and legal freedom to marry.

N-400

Translate any foreign-language evidence submitted regarding marital history, children, court matters, or identity.

When primary documents are unavailable

USCIS Policy Manual guidance on evidence explains that where primary evidence is generally available, USCIS expects it. If a primary civil document does not exist or cannot be obtained, the applicant generally must show that unavailability and then provide secondary evidence. The Department of State reciprocity schedule is the starting point for figuring out what documents are considered generally available in a specific country.

This matters for translation because secondary evidence also needs translation if it is not in English. For example, if you cannot obtain a birth certificate and instead submit a baptismal record, school record, affidavits, or a non-availability letter from a foreign authority, those documents still need full English translations.

Certified translation for USCIS vs notarized translation

This is one of the most searched immigration questions for a reason. Certified translation for USCIS means the translator signs a certification that the translation is complete and accurate and that the translator is competent in both languages. Notarized translation usually means the translator signed that statement in front of a notary, and the notary verified the identity of the signer.

For USCIS, notarization is usually optional unless some other authority specifically requires it. Paying for notarization when USCIS only needs certification often adds cost without adding legal value.

Can you use Google Translate, DeepL, or AI?

For understanding your own documents, machine translation can be useful. For filing evidence, it is risky. USCIS requires a translator's certification. A machine cannot make that certification, and machine output often misses context, handwriting, seals, or registry language. For records that matter to eligibility, a human translation is the safer choice.

How much does certified translation for USCIS usually cost?

Corpus Localization charges $19.99/page for standard personal documents.

Final checklist before filing

Before mailing or uploading your USCIS packet, confirm:

• Every foreign-language document has a full English translation
• The translation includes stamps, notes, and annotations where relevant
• The translator signed a certificate of accuracy and competence
• Names, dates, and document numbers match the original record
• The translated copy is legible and clearly paired with the original

That checklist sounds basic, but it prevents a large share of avoidable RFEs.

FAQPage schema-ready Q&A

What documents need translation for Form I-130?

Birth certificates, marriage certificates, divorce decrees, death certificates, adoption records, and any other supporting civil records submitted in a foreign language should be translated completely into English with a translator certification.

Does Form I-485 require a certified translation for birth certificate evidence?

Yes. If the birth certificate is not in English, USCIS requires a complete English translation plus a certification from the translator that the translation is accurate and that the translator is competent.

Does USCIS require notarized translations?

Usually no. USCIS generally requires certified translations, not notarized translations, unless a separate agency or authority specifically asks for notarization.

Can I use the same translation for I-130 and I-485?

Usually yes, if the translation matches the exact version of the document being submitted and includes a proper certification. If the underlying document has changed or a newer certified copy was issued, update the translation.

Do bank statements and leases need translation for I-751?

If you are relying on foreign-language bank statements, leases, or similar documents as material evidence of a bona fide marriage, they should be translated into English so USCIS can evaluate them.

What if my country does not issue the civil document USCIS wants?

Check the Department of State reciprocity schedule. If the primary document is unavailable, USCIS may accept secondary evidence, but any secondary evidence submitted in another language must also be translated into English.
