Yes. In an O-1A petition focused on academic work, recommendation letters from former professors can be a valuable element. They help attest to the recognition of your expertise and the relevance of your contributions, coming from people who witnessed your trajectory firsthand.

Even so, a single letter cannot sustain a petition on its own. Each piece of evidence is part of a larger package that must consistently demonstrate your extraordinary ability. Letters carry the most weight when they reinforce concrete facts.

  • They detail how your work stands out in the academic field.
  • They support awards, publications, conferences, and relevant collaborations.
  • They are signed by professionals with established credibility in the field.

Because the evaluation considers the full body of documentation, it is worth building a solid and coherent case. Check the updated requirements on official sources such as USCIS and, when possible, work with a specialist to organize your evidence.
