Evidence and recommendation letters

Letters that explain why your work matters

For O-1, EB-1A, EB-1B and EB-2 NIW petitions, recommendation letters and a well organized exhibit record turn a strong career into evidence an officer can follow. We identify the right recommenders, draft letters in their voice for review and signature, and map every page to the criteria it proves.

Why letters matter

Officers are generalists. Your field is not.

An adjudicating officer may review a machine learning paper in the morning and a choreographer's portfolio in the afternoon. Letters supply the expert context they cannot supply themselves.

i.

They explain significance

A citation count or a product launch means little on its own. A respected expert explains what changed in the field because of it.

ii.

They connect the exhibits

Good letters point to specific documents in the record, so press, contracts and publications read as one consistent story.

iii.

They support key criteria

Original contributions of major significance and critical roles at distinguished organizations rely heavily on expert testimony.

iv.

They are not enough alone

Letters work best when they corroborate documentary evidence. A letter that stands without exhibits carries much less weight.

Types of letters

Independent experts and close collaborators

A strong petition usually includes both. Each type answers a different question for the officer.

Answers: does the field recognize you?

Independent expert letters

Written by recognized people who have not worked with you directly but know your work through its influence: they cite it, use it, review it or have seen it change practice.

  • Show recognition beyond your own employer and network
  • Carry particular weight for international or national acclaim
  • Typical writers: senior academics, industry leaders, editors, festival or league officials
Answers: what exactly did you do?

Collaborator letters

Written by people who saw your work up close: managers, co-founders, co-authors, directors, coaches. They give first-hand detail on your role and the results that followed.

  • Document critical and leading roles with specifics only insiders know
  • Explain internal impact that never appeared in public sources
  • Most persuasive when the writer holds a senior, verifiable position

For O-1 petitions, a written advisory opinion from a peer group, labor organization or expert in the field is also required. We help you identify the right source and prepare the request. Read more on the O-1A criteria and the EB-1A criteria.

Our process

From the right recommenders to a signed letter

Every letter is drafted from real conversations and real facts, reviewed and revised by the writer, and signed only when it says what they believe.

  1. 1

    Identify recommenders

    We review your record and build a shortlist that balances independent experts and collaborators, with each person chosen for the criteria they can speak to credibly.

    You provide: your network, introductions where needed

  2. 2

    Interview and gather facts

    We speak with you, and where possible with each recommender, to capture how they know your work, what it changed, and the concrete details that make testimony credible.

    You provide: context, documents, dates

  3. 3

    Draft for review and signature

    We prepare a draft in the recommender's own voice and expertise. They edit freely, confirm every statement is accurate, and sign on their letterhead.

    Recommender provides: edits, CV, signature

  4. 4

    Map each letter to criteria

    Every letter is cross-referenced to the criteria it supports and the exhibits it corroborates, so your partner attorney receives a petition where testimony and evidence align.

    You receive: signed letters and a criteria map

Evidence exhibits

An exhibit record an officer can navigate

A petition can run to hundreds of pages. We organize it so each claim is easy to find, verify and connect to the standard it meets.

01

Indexing by criterion

A numbered exhibit index groups documents under each criterion, with short descriptions of what each item shows.

02

Certified translations

Any document not in English needs a full English translation with a translator's certification. We track and coordinate these so nothing arrives incomplete.

03

Context for every source

Press, journals, events and organizations come with evidence of their standing, such as circulation, reach or selectivity, so the officer can judge their weight.

04

One consistent narrative

Dates, titles, metrics and descriptions match across your CV, letters, exhibits and the petition letter. Inconsistencies are a common source of doubt.

What makes a letter strong

Do's and don'ts of recommendation letters

The difference between a letter that persuades and one that is skimmed usually comes down to specifics.

Strong letters

  • Explain who the writer is and why their opinion carries weight in the field
  • State how the writer knows the work, directly or through its influence
  • Name concrete contributions and the measurable or observable impact that followed
  • Compare your standing to others in the field in plain terms
  • Reference exhibits that corroborate each claim
×

Weak letters

  • Rely on praise such as "brilliant" or "world class" without facts behind it
  • Read like templates, with the same phrasing across several recommenders
  • Restate the CV instead of explaining significance
  • Come only from close colleagues, with no independent voices
  • Contain claims the writer cannot personally stand behind

FAQ

Questions about recommendation letters

Straight answers on letters for O-1, EB-1A, EB-1B and EB-2 NIW petitions.

How many recommendation letters do I need?

There is no fixed number in the regulations. Many strong petitions include several letters, but quality and fit matter more than count. We plan the set so each letter covers distinct criteria and adds something the others do not.

Who should write my letters?

A mix of recognized independent experts and senior collaborators who know your work well. Seniority and relevance to your field matter more than fame outside it. We help you choose and approach them.

Is it acceptable for you to draft the letter?

Busy experts often prefer to start from a draft. What matters is that the content is true and the writer stands behind it. Every draft we prepare is reviewed and edited by the recommender, who signs only a letter that reflects their own views.

Do recommenders need to be in the United States?

No. Letters from experts in other countries can help show international recognition. If a letter is not written in English, it needs a certified English translation.

Are letters different for O-1, EB-1A and EB-2 NIW?

Yes. O-1 and EB-1A letters focus on the criteria and your standing in the field. EB-2 NIW letters focus on the three Dhanasar prongs, especially the national importance of your proposed endeavor and how well positioned you are to advance it. See EB-2 NIW for more.

Can I use letters I already have?

Often as a starting point. Reference letters written for jobs or grad school rarely address immigration criteria, so we usually ask the writer to prepare an updated letter for the petition.
