Expert Letter Drafter

How This Skill Works

1. Intake — Gather the expert roster and petition details
2. Strategy — Assign criteria/topics to experts based on their credentials
3. Draft — Write each letter with a unique angle
4. Review — Check that letters don't overlap and collectively cover everything needed

Phase 1: Intake

Required information

1. Petition type — O-1A, EB-1A, or NIW
2. Beneficiary — name, field, key accomplishments (from document index or petition package)
3. Criteria being argued — which criteria need expert letter support
4. Expert roster — for each expert:

Optional: If case-strength-assessor was already run on the document index, use its WEAK/MODERATE ratings to prioritize which criteria need the strongest independent expert coverage and which gaps letters alone cannot fix.

Expert types (from strongest to weakest for USCIS)

Best practice: Include at least 2 independent or industry experts. An all-colleague roster is weak.

Phase 2: Strategy — Assign Topics to Experts

The assignment matrix

Each expert should cover different criteria/topics. No two letters should argue the same thing the same way.

Build this matrix before drafting:

| Expert | Their Credential | Criteria/Topic Assigned | Unique Angle |
|--------|-----------------|------------------------|-------------|
| Dr. X (Professor, MIT) | AI researcher, 200+ publications | Criterion 5 (original contributions) | Can speak to how the beneficiary's research advances the field — independent perspective |
| Y (VP Engineering, Company B) | Industry leader, same field | Criterion 6 (critical role) + Criterion 2 (membership) | Worked in the field 15 years, can contextualize the beneficiary's standing relative to peers |
| Z (Former manager, Company A) | Direct supervisor | Criterion 6 (critical role at Company A) | Firsthand knowledge of specific contributions and measurable impact |
| W (VC Partner, Firm) | Investment decision-maker | Criterion 1 (awards/VC funding) + Criterion 2 (membership/accelerator) | Made the investment decision — can explain selectivity and why the beneficiary was chosen |

Assignment rules

• Match credential to criterion. A VC partner should write about the funding decision (criterion 1) and accelerator selectivity (criterion 2), not about the beneficiary's code quality. A professor should write about scholarly contributions (criterion 4/5), not about business operations.
• At least one letter per argued criterion. Every criterion in the petition should have at least one expert letter supporting it.
• No two letters argue the same criterion the same way. If two experts address criterion 6 (critical employment), they should cover different roles or different aspects.
• At least one letter from an independent expert. Someone with no financial or employment relationship to the beneficiary.
• For NIW: at least one letter addressing national importance. An expert who can speak to why the beneficiary's work matters to the U.S.

Phase 3: Draft Each Letter

Letter structure

Every expert letter follows this structure:

[Date]

U.S. Citizenship and Immigration Services
[Service Center address]

RE: [Form I-129/I-140], [Petition Type] Classification
    Petitioner: [Company/Self]
    Beneficiary: [Name]

Dear Immigration Officer,

[PARAGRAPH 1: Who I am]
[PARAGRAPH 2: How I know the beneficiary]
[PARAGRAPH 3-5: Specific testimony on assigned criteria]
[PARAGRAPH 6: Summary opinion — the beneficiary qualifies]
[CLOSING]

Sincerely,

_______________
[Name]
[Title]
[Organization]
[Contact info]

Paragraph-by-paragraph guidance

Paragraph 1: Who I Am (establish credibility)

The writer introduces themselves with credentials that establish why USCIS should listen to them.

Include:

• Full name, current title, organization
• Years of experience in the field
• Key credentials (degrees, publications, patents, awards, leadership roles)
• Why they are qualified to evaluate talent in this specific field

Good: "I am the Chief Scientist and Co-Founder of [Company], where I lead a team of 40 engineers developing [technology]. I hold a Ph.D. in Computer Science from [University] and have published 85 peer-reviewed papers in [field]. I have 20 years of experience in [field]."

Bad: "I am a successful professional in the technology industry." (No specifics, no credentials)

Paragraph 2: How I Know the Beneficiary (establish personal knowledge)

USCIS needs to know the writer has genuine knowledge of the beneficiary's work — not just heard about them.

Include:

• How and when they first encountered the beneficiary's work
• The nature of the professional relationship
• Specific interactions or context for their knowledge

Good: "I first became aware of [Beneficiary]'s work in 2022 when I reviewed their publication on [topic] in [journal]. I subsequently collaborated with them on [project] and have followed their career closely since."

Bad: "I know the beneficiary and their work." (No specifics on how or when)

For independent experts: Explain how they came to know the work even without a direct relationship — through publications, conference presentations, industry reputation, media coverage.

Paragraphs 3-5: Substantive Testimony (the core)

This is where the expert addresses the assigned criteria. Each paragraph should:

1. State the specific criterion being addressed (without using USCIS jargon — write naturally)
2. Describe what the beneficiary did — with SPECIFIC, VERIFIABLE facts
3. Explain why it matters — the expert's professional opinion on the significance
4. Compare to the field — how does this stack up against others in the same field?

Rules:

• Cite specific facts the expert has personal knowledge of — don't repeat the petition's exhibit descriptions
• Include the expert's own assessment of WHY the work is significant — this is what makes an expert letter valuable
• Compare the beneficiary to others in the field — "In my 20 years in this field, I have encountered fewer than 5 engineers with this combination of skills"
• Each fact should be something the expert can independently verify if called upon
• Avoid generic praise — "brilliant," "exceptional," "outstanding" without specific backing is worthless
• The expert should explain things in their own professional voice, not sound like a lawyer wrote it

Good: "The [specific system] that [Beneficiary] designed at [Company] processes [X] events per second with [Y]% accuracy. In my experience leading similar systems at [My Company], achieving this level of performance requires deep expertise in [specific technologies]. The approach [Beneficiary] developed — [describe approach] — was novel because [why]. I am not aware of any other system in the industry that achieves comparable results through this method."

Bad: "The Beneficiary made outstanding contributions of major significance to the field." (This is USCIS criterion language — a real expert wouldn't talk like this)

Paragraph 6: Summary Opinion

The expert's conclusion. Should directly support the petition's classification.

For O-1A/EB-1A: "Based on my professional experience and direct knowledge of [Beneficiary]'s work, I believe [Beneficiary] is among the small percentage of professionals who have risen to the very top of the field of [Field]. Their contributions to [specific area] demonstrate sustained excellence that distinguishes them from their peers."

For NIW: "Based on my professional experience, I believe [Beneficiary]'s continued work in the United States will substantially benefit the nation. Their expertise in [field] addresses a critical need in [national problem], and their track record demonstrates they are well positioned to advance this important endeavor."

What makes a STRONG letter vs. a WEAK letter

Phase 4: Review — The Non-Overlap Check

After drafting all letters, verify:

Coverage matrix

| Criterion | Expert A | Expert B | Expert C | Expert D | Covered? |
|-----------|----------|----------|----------|----------|----------|
| 1. Awards | | ✓ | | | Yes |
| 2. Membership | | ✓ | | | Yes |
| 4. Original contributions | ✓ | | | | Yes |
| 6. Critical employment | | | ✓ | ✓ | Yes (different roles) |
| 8. Judging | | | | ✓ | Yes |

Overlap check

• Do any two letters make the same argument about the same criterion? If yes, differentiate them.
• Does every criterion have at least one letter supporting it?
• Is there at least one independent expert?

Tone check

• Does each letter sound like the EXPERT wrote it, not a lawyer? Different experts should have different voices.
• Does the language avoid sounding like it was mass-produced from a template?

Best Practices

• Each expert MUST review and customize their letter — it must reflect their genuine opinion in their own words. The draft is a starting point, not a final product.
• Never fabricate an expert's credentials or experience
• An expert letter that sounds like a lawyer wrote it is a red flag for adjudicators — use natural professional language
• Independent experts are worth more than 3 colleagues — prioritize quality over quantity
• The expert should be able to defend every statement in the letter if questioned
• For NIW: at least one expert should specifically address why the beneficiary's work matters to the U.S. nationally
• For EB-1A: at least one expert should address "sustained" acclaim — not just a one-time achievement
• Include the expert's contact information (email, phone) — USCIS occasionally verifies
• Each letter should reference specific, verifiable facts — vague praise gets discounted
• The best letters include comparisons: "In my N years in this field, I have seen fewer than X people with this capability"
