Recommendation Letter Not in English: College Rules

Recommendation Letter Not in English: College Rules

Yes, a teacher can write a US college recommendation in another language, but the letter must arrive with an English translation and, at most colleges, the original. The student may never be the translator. Who else may translate, and whether it must be "certified" or "notarized", depends on the college.

You may have read that a recommendation letter needs a "certified translation." That is some colleges' rule, not every college's. Harvard and Princeton say you do not need to pay a professional. Yale and Penn ask for a certified translation. Boston University asks for a notarized one. Because a Common App letter goes to every college on the list, the translation has to satisfy the strictest college the student applies to. This page gives the rules in each college's words, a decision rule for the teacher, and a translator's statement you can copy. Teachers drafting the letter itself can use the Common App teacher letter rubric as a check.

Every college page quoted below was checked on October 30, 2026. None of them states a cycle year, so recheck each page before the letter is uploaded.

The one rule every college shares

The student does not translate. Three colleges say it outright:

• Harvard: "you should not translate the documents yourself."
• Yale: "We are not able to accept any documents that you have translated yourself."
• Stanford: "Applicants cannot translate the documents themselves."

The other four colleges in the table below do not use those words, but none of them permits it. Each one points to a school official, a third party, or a formal certification.

Our reading: a parent, a sibling or a paid education agent translating the letter is the applicant's side doing the translating. No page bars a parent by name, but Harvard asks for the translator's "relationship to you" and gives an English teacher as its example, and Princeton and Stanford point to school officials. Keep the family and any agent out of it.

College-by-college translation rules

These are the exact sentences on each college's international applicant page, checked October 30, 2026.

Three things in that table change the plan:

1. "Certified" is not defined. Neither Yale's page nor Penn's says who may certify. A school translation signed and stamped by the principal may or may not meet it. If either college is on the list, email its admissions office and ask before paying for anything.
2. Notarized is a different thing. BU's word refers to a notary, not a teacher. If the student applies to BU, plan for that cost and lead time.
3. Princeton is explicit that the form itself can be in another language. Its page says a teacher or counselor "not comfortable writing in English … may complete the forms in another language. However, you will need to have the forms officially translated before they are submitted to the Admission Office." Note what that last clause says: the translation is in place before the upload, not sent later.

Two more colleges set rules for other documents. Caltech says "We will not review your application if any part is not translated in English" and suggests "asking an English teacher or school official to translate the document" for transcripts. USC asks for school records in the native language "accompanied by a certified English translation". USC's page does not mention letters.

One more exception: Princeton's graded written paper and its teacher comments "should not be translated from another language into English, they must be written in English."

Should the teacher write in English or their own language?

The Common App recommender system is, in Common App's recommender guide, "a one-and-done process. That means that once you submit a form, it's sent to all the colleges you're assigned to." One file serves Harvard and BU alike. So the decision is made once, for the whole list.

Our view: the teacher should write in the language in which they can be specific. A letter's value is detail: the question the student asked in week three, how their lab report changed after feedback, where they rank among students the teacher has taught. A teacher who writes those details well in Spanish or Mandarin and vaguely in English should write in Spanish or Mandarin and get it translated.

The countercase: if the teacher writes clear, plain English, even with small errors, they should write in English. A translation adds a second person, a second document and, for BU, a notary. Our view is that plain English with real detail beats polished English with none.

The rule for the translation itself: match the strictest college on the student's list.

Attaching the original costs nothing, and Harvard, Stanford, Columbia and BU ask for it. Do it every time.

Unknown: none of these pages addresses a teacher who drafts in their own language and then uses a translation tool to produce an English letter. Our recommendation: if the teacher does that, the English version is the teacher's own letter, and the teacher must read and stand behind every sentence. Do not label it a translation, and do not let anyone else "fix" it.

How to submit an original plus translation in Common App

The recommender uploads the letter in the recommender system; the student never handles it. The guide says counselors, teachers and other recommenders "all have the opportunity to upload a letter of recommendation." Here is the order we recommend:

1. The teacher writes and signs the letter in their language.
2. The translator (an English teacher or school official, never the student) translates it in full. No summarizing, no improving.
3. The translator adds a short statement, as in the example below.
4. The school combines three parts into one file in this order: the English translation, the translator's statement, then the original.
5. The teacher uploads that one file and submits. Once submitted, the guide says, "you can't modify it."

If the list includes BU, the notarized version replaces step 3's statement or sits beside it, as the notary requires.

We did not verify the recommender system's file-size or page limits; check them in the system before combining.

Constructed example: a translator's statement

Constructed example, written by us, not a real school's document. Context (invented): an English teacher translates a chemistry teacher's letter for a student applying to Harvard and Stanford.

Translator's statement

I translated the attached letter of recommendation for Lucía Ferraro from Spanish into English. The letter was written by Mr. Andrés Villalba, chemistry teacher at Colegio Monteverde. I am Ms. Clara Ibáñez, English teacher at the same school, and I taught Lucía English in grades 10 and 11. I am not related to her. The translation is complete and I have not added, removed or changed any content. The original letter follows this page.

Clara Ibáñez, English Department, Colegio Monteverde. December 1, 2026.

Why it works: Harvard asks for "the name of the translator and his/her relationship to you", and this names both. It says the translation is complete, which answers the question a reader of a short translation would ask. It points to the original. It would not meet Yale's or Penn's "certified" wording without that college's confirmation, or BU's notarization.

What not to do

• Do not write the letter for the teacher. A student or parent who drafts an English letter for a teacher to sign risks what Common App's fraud policy lists first: "Submitting fabricated or materially misleading letters of recommendation." GradPilot's letter reviews aren't for a letter you drafted for a recommender to submit as their own.
• Do not let an agent "polish" the translation. A translation that adds praise the teacher did not write is a materially different letter. The education agent rules cover what agents should never touch.
• Do not send the translation from your own email. Letters travel through the recommender system. The fraud policy also names "Circumventing the use of official counselor communication channels."
• Do not skip the original because one college does not ask for it. The same file goes to every college.

The same translation question comes up for the School Report and counselor letter. If your school has no counselor, applying to US colleges without a counselor covers who signs. Teachers writing in English as a second language can start with the ESL teacher recommendation letter guide.

Questions about recommendation letters in other languages

Do recommendation letters need to be in English for US colleges?

They must reach the college in English. Yale says "All application materials must be in English." The letter can be written in another language if an English translation is attached, and Princeton states this directly for teacher recommendations and the School Report.

Does the translation have to be certified?

At Yale and Penn, their pages say certified. At BU, notarized. Harvard says you do not need a professional translator, and Princeton says "paid translations are not required." Meet the strictest rule on the student's list.

Can my parent translate my recommendation letter?

We advise against it. Harvard, Yale and Stanford bar the applicant from translating, and none of the seven pages names a parent as an acceptable translator. Use an English teacher or school official.

Can the teacher send the original and translation as two files?

The recommender system gives each recommender one letter upload in our reading of Common App's guide. Combine them into one file.
