When you're putting together an EB-1A Extraordinary Ability petition, expert letters can feel like one of the most important and most confusing parts of the case.

A lot of people assume that simply getting well-known experts to say positive things about their work will be enough. In reality, that's not what U.S. Citizenship and Immigration Services is looking for. What matters is not just who is writing the letter, but what the letter actually explains.

A helpful way to think about expert letters is this:
they are not meant to repeat your resume, they are meant to explain your impact.

A Real Case Example

There was a recent case reviewed by the Administrative Appeals Office involving a senior engineer in the semiconductor field.

The petition included multiple expert letters from professionals in the industry. On the surface, this looked strong. But the case was still denied—and the appeal was dismissed.

Why?
Because the letters, while supportive, did not clearly explain how the individual's work had influenced the field in a meaningful way.

This is where most EB-1A cases fall short.

A Common Misconception About Expert Letters

If you're requesting expert letters, it is completely acceptable to ask people to write them for your case.

USCIS does not automatically discount letters just because they were requested. In fact, the AAO has made it clear that there is no rule saying solicited letters carry less weight than other evidence.

The issue is not whether the letters were requested the issue is whether they are persuasive.

What Strong Expert Letters Do

Strong expert letters usually do a few key things:

1. Explain your work in plain terms
Not just titles or projects, but what your work involved and why it mattered.

2. Show how your work moved the field forward
This is critical. USCIS is looking for “original contributions of major significance,” which means the letter should explain what changed because of your work.

3. Provide specific examples
For example:

• Did companies adopt your methods?
  
  

• Did your research lead to new applications, products, or standards?
  
  

• Did others build on your work?
  
  

4. Go beyond general praise
Letters that only say someone is “impressive,” “skilled,” or “respected” tend to carry very little weight.
USCIS is not evaluating personality they are evaluating impact.

Why the Case Failed

In the case mentioned above, the letters described the importance of the field and the individual's work within it.

However, they did not clearly show how his contributions had been:

• adopted,
  
  

• applied, or
  
  

• recognized beyond his immediate company or clients.
  
  

That gap was enough for the case to fail.

The Importance of Reach

Another important point is reach.

USCIS often looks at whether your contributions extend beyond your own organization. If your work only benefits your employer internally, it may not meet the “major significance” standard - unless it clearly influences the broader field.

A Simple Test for Your Letters

If you're preparing your EB-1A case, review your letters with this question in mind:

If someone outside your industry read this, would they understand what you changed and why it matters?

If the answer is no, the letter probably needs more detail.

Final Thought

Expert letters can be one of the most powerful parts of an EB-1A petition when they are done correctly.

But they need to be:

• intentional,
  
  

• specific, and
  
  

• focused on impact - not just credentials.
  
  

If you're unsure whether your letters are strong enough, it's worth reviewing them carefully before submitting. Small changes in how your work is explained can make a significant difference in how your case is evaluated.
