What is the Difference Between a Certified Document Translation & a Sworn Translation?

When you need to submit foreign-language documents in the United States—especially for USCIS, immigration, universities, or courts—you’ll often hear two terms: Certified Document Translation and Sworn Translation. These phrases sound similar, but they are not the same, and using the wrong type can delay your case.

At Unlimited Ink Notary, Certified Document Translation, and Apostilles, we provide both certified and sworn translations nationwide. This guide explains which one you actually need—and why most people in the U.S. will never require a sworn translation at all.

What Is a Certified Document Translation?

A Certified Document Translation is the standard required throughout the United States for immigration and most legal purposes. It is a translation accompanied by a signed Certificate of Accuracy from the translator or translation company. The certification states that:

• The translation is complete and accurate

• The translator is competent in both languages

• The document was translated to the best of the translator’s ability

• 
  

This is the format USCIS and federal agencies require when submitting birth certificates, marriage certificates, diplomas, police records, and other foreign documents. According to USCIS guidance, translations must include a signed certification from the translator verifying accuracy and competence (see official requirements at uscis.gov).

👉 Important: USCIS does not ask for notarization or a sworn translation—only a properly formatted certified translation.

Common uses include:

• USCIS immigration filings

• Green card and visa applications

• Passport and ID translations

• School and university enrollment

• Employment verification

• 
  

What Is a Sworn Translation?

A Sworn Translation is completely different. This type is used mainly in civil-law countries outside the United States, such as Spain, France, Brazil, or Germany. The translator is officially licensed by a foreign government and must swear before a court or notary that the translation is true.

Sworn translations are typically required for:

• Foreign court proceedings

• Real estate transactions abroad

• Dual citizenship applications in certain countries

• Registrations with overseas ministries

In the U.S., government agencies—including USCIS—do not require sworn translations. Requesting one can actually create confusion, higher costs, and unnecessary delays.

If You’re Filing With USCIS, You Do NOT Need a Sworn Translation

This is the most common misunderstanding we see.

For U.S. immigration purposes:

✔ You need a Certified Document Translation

❌ You do not need a sworn translation

❌ You do not need embassy legalization for USCIS filings

USCIS only requires that the translation be accompanied by a signed certificate of accuracy. This guidance is outlined on the official USCIS website and applies nationwide.

How to Choose the Correct Service

Ask yourself these two questions:

1. Is the document being submitted inside the United States?→ You almost always need a Certified Translation.

2. Is it for use in another country or foreign court?→ You may need a Sworn Translation instead.

3.
