Why a Testimonial Letter in a Foreign Language Can Be More Powerful

When building an extraordinary ability or national interest profile, many applicants focus only on English-language recommendation letters. But foreign-language testimonial letters can be even more powerful—if used correctly.

Here’s why.

1. International testimonials show global recognition

A testimonial written in the expert’s native language demonstrates something that an English-only letter cannot:

Your influence is not limited to one country.

It signals:

• global reach

• cross-border relevance

• impact in multiple markets

• recognition outside the US system

USCIS values international acclaim, and foreign-language letters help prove that the recognition is authentic and not US-centric.

For example if you worked for LATAM (Latin America, referring to the culturally linked regions of the Americas where Romance languages (Spanish, Portuguese, French) are predominantly spoken), receive the testimonial letter in their own language.

2. Experts write more honestly in their own language

When an expert writes in English, their tone may feel:

• restrained

• formal

• overly structured

But in their native language, they often express:

• deeper respect

• cultural nuances

• stronger endorsement

• clearer descriptions of your contribution

This authenticity makes the letter more compelling.

3. It removes the sense that the petitioner drafted the letter

USCIS officers know that many English testimonials are ghostwritten by attorneys or clients.

A letter written entirely in the expert’s native language:

• feels original

• shows independent authorship

• carries natural voice and vocabulary

• reduces suspicion of “template-style drafting”

With a certified English translation attached, it becomes one of the most credible pieces of evidence.

4. It strengthens claims related to international impact, contribution, or recognition

Foreign-language testimonial letters are especially persuasive for:

• EB-1A original contributions

• EB-1A judging evidence

• EB-1A leading or critical role

• EB-2 NIW national importance

• O-1A sustained acclaim

They help show that your work influences people across regions, not just in English-speaking communities.

5. Below is the USCIS requirement you must follow

A foreign-language letter must be submitted with:

• a full certified English translation,

• the translator’s signature,

• a statement of accuracy,

• and the translator’s credentials.

This is required under 8 C.F.R. § 103.2(b)(3).

Without the certified translation, USCIS cannot consider the letter at all.

6. Combine both versions for maximum credibility

When you submit:

• Original letter in the expert’s language

• Certified English translation

• Expert’s CV or bio

It becomes one of the strongest evidence types in your entire portfolio.

You get:

• authenticity from the original

• legal compliance from the translation

• clarity for USCIS from the English version

Yes, testimonial letters in foreign languages are often more powerful, because they bring authenticity, emotion, and originality that English versions sometimes lack. As long as you attach a certified translation, they strengthen your claim of global acclaim.
