The O-1 Advisory Opinion Mistake That Keeps Generating RFEs (And How to Fix It)

If you're filing an O-1 visa petition in a field without a traditional union or peer group, there's a small mistake that's generating RFEs left and right—and it's completely avoidable.

I see this issue constantly on cases prepared by other attorneys that land on my desk after USCIS kicks them back. It's a simple fix on the front end, but an unnecessary delay if you miss it.

Let me explain what's happening and how to get it right.

The Mistake

When there's no union or peer group for a beneficiary's field—which is increasingly common in tech, startups, digital marketing, AI, e-commerce, and other emerging industries—attorneys have traditionally written something like this in their cover letters:

"There is no peer group or labor organization for the beneficiary's field. In lieu of an advisory opinion, we are submitting expert letters from individuals qualified to assess extraordinary ability."

For years, this approach worked. You'd submit a stack of strong expert letters, explain that no formal peer group exists, and move on.

Not anymore.

USCIS is now issuing RFEs specifically on this point. They're asking petitioners to identify which letter serves as the official advisory opinion required under the regulations.

In other words, you can no longer treat your expert letters as a collective substitute for the advisory opinion. You need to designate one.

What the Regulations Actually Require

Under 8 CFR 214.2(o)(2)(iii), O-1 petitions require a written advisory opinion from a peer group, labor organization, or a person with expertise in the beneficiary's field.

When no peer group exists, subsection (C) allows for an advisory opinion from "a person or persons with expertise in the area of the alien's ability."

The key word is "advisory opinion"—singular and specific.

USCIS wants to see one letter clearly designated as fulfilling this regulatory requirement. Your other expert letters support the case and speak to specific criteria, but they don't replace the need for a formal advisory opinion.

The Simple Fix

The solution is straightforward:

Explicitly designate one letter as your official advisory opinion.

In your cover letter, instead of vaguely referencing your expert letters as a substitute, write something like:

"As no peer group or labor organization exists for the beneficiary's specialized field of [field], we are submitting the letter from [Name], [Title], as the formal advisory opinion pursuant to 8 CFR 214.2(o)(2)(iii)(C). [Name] is an independent expert in [field] who is qualified to assess what constitutes extraordinary ability in this area and whether the beneficiary meets that standard."

Then make sure the letter itself is structured as an advisory opinion—not just a general support letter. It should:

• Establish the writer's qualifications and expertise in the field

• Explain what constitutes extraordinary ability in this specific field

• Assess whether the beneficiary meets that standard

• Confirm the writer's independence from the beneficiary

  
  

That's it. Clear designation. Clear language. No ambiguity.

Who Should Write the Advisory Opinion?

The ideal advisory opinion writer is:

1. A peer expert in the beneficiary's specific field

They should have direct knowledge of the industry, the standards for excellence, and what distinguishes ordinary practitioners from extraordinary ones.

2. Independent

This is critical. The writer should have no prior working relationship with the beneficiary. That means they're not a current or former client, employer, co-founder, business partner, or close collaborator.

Why does independence matter? USCIS wants to see that someone without a vested interest in the petition's outcome looked at this person's work and concluded, "Yes, this is extraordinary." An independent assessment carries more weight than a letter from someone who directly benefits from the beneficiary's continued presence in the U.S.

3. Qualified to opine on extraordinary ability

The writer should be able to speak credibly about what "extraordinary" means in the beneficiary's field. This often means someone with significant experience, recognition, or seniority in the industry.

You Don't Need to Pay for This Letter

Here's something many people don't realize: you don't need to hire a paid expert witness to write your advisory opinion.

Acquaintances in the field work just fine.

The advisory opinion can come from someone who:

• Knows the beneficiary's work from a distance

• Follows their contributions in the industry

• Has observed their reputation among peers

• Has encountered their work at conferences, through publications, or via industry channels

  
  

You're not asking for a formal expert report. You're asking a respected peer to offer their professional assessment of the beneficiary's standing in the field.

In fact, an unpaid letter from a genuine industry peer often carries more weight than a paid opinion from a hired expert. It signals authentic recognition from the field itself.

So reach out to acquaintances. Tap into your professional network. Find someone who respects the beneficiary's work but hasn't directly worked with them. That's your ideal advisory opinion writer.

Your Other Expert Letters Still Matter

To be clear: this doesn't mean you should only submit one letter.

Your other expert letters remain important. They corroborate the case, speak to specific O-1 criteria, and provide detailed evidence of the beneficiary's achievements, contributions, and recognition.

But those letters serve a different purpose than the advisory opinion. They're supporting evidence. The advisory opinion is a regulatory requirement.

Make sure one letter is clearly designated as the advisory opinion. The rest can be labeled and organized as expert letters or testimonials supporting specific criteria.

Why This Matters

An RFE on the advisory opinion issue is frustrating because it's entirely preventable.

The fix takes one sentence in your cover letter and some basic structuring of one of your letters. That's it.

I've seen this RFE come up repeatedly on cases from other attorneys. It's not a reflection of the strength of the case—it's a technical issue that's easy to overlook if you're not paying attention to how USCIS adjudication trends are shifting.

Key Takeaways

If you're preparing an O-1 petition in a field without a traditional peer group:

1. Don't write that you're submitting expert letters "in lieu of" an advisory opinion

2. Do explicitly designate one letter as your formal advisory opinion

3. Choose an independent peer expert as your advisory opinion writer

4. You don't need to pay for this letter—acquaintances in the field work great

5. Structure the designated letter to address the regulatory requirements

6. Label your other letters as supporting expert letters or testimonials

   
   

It's a small adjustment that can save you significant headaches down the road.
