25 mistakes that cost international students a US admission

None of them is spectacular. All of them happen every year to students who had the grades. Reread this list before every submission.

Data updated September 25, 2026

List and strategy

  1. Only universities under 15%. Even an exceptional application can end up with nothing.
  2. An unaffordable "likely". If it gives no aid to internationals and you need aid, it doesn't count.
  3. Two Early Decisions at once. Not allowed, and risky.
  4. An Early Decision without running the numbers. You commit before you can compare.
  5. Fifteen universities or more. Supplement quality collapses.

Tests

  1. An English test the university doesn't accept. Check every university before you register: see which universities list the Duolingo English Test.
  2. An SAT whose scores arrive after the deadline. Count the score date, not the test date.
  3. Sending a score below the range of a test-optional university.
  4. Assuming "optional" applies to you. Some universities still ask internationals for scores.

The application

  1. Converting your grades into a GPA yourself. Let the School Profile explain your system.
  2. Leaving out your job or family responsibilities from your activities.
  3. Activity descriptions with no verbs and no numbers.
  4. A typo in self-reported grades, discovered in the final transcript.

Essays

  1. A formal dissertation instead of an essay: announced plan, a conclusion that sums up.
  2. An essay anyone could have written.
  3. Another university's name in a "Why us". The most fatal mistake, and the most common.
  4. A "Why us" about reputation and a beautiful campus.
  5. An essay written or rewritten by someone else, or by an AI.

Letters

  1. Asking for letters two weeks before the deadline.
  2. Not waiving your right to read them (the FERPA waiver).
  3. Leaving a teacher with no idea what an American letter is.

Money

  1. Not applying for aid when you apply, planning to ask later.
  2. Preparing financial documents in May: the I-20 and the visa fall behind.

Submitting

  1. Submitting on the last night. Overloaded servers, time zones, declined payments.
  2. Never opening the portal after submitting, and finding out in April that a document was missing.

Questions

What is the most common mistake in a "Why us" essay?

Leaving another university's name in it after reusing the essay, closely followed by writing about reputation and a beautiful campus instead of what you would actually do there.

Can I apply Early Decision to two universities?

No. Early Decision is binding and you can only have one active Early Decision application at a time.

Is it a mistake to apply to too many universities?

Beyond fifteen, the quality of supplemental essays usually collapses. Eight to twelve well-chosen universities is a common target.
