Ask ten people for a letter and most will say yes, then ask you to send them a draft. Accepting that offer is the single most common way a strong record produces weak letters.
- Specific claims, not a request for general praise
- Evidence attached, so the writer can point at something
- The writer's own words, in their own voice
- The basis of their knowledge, stated explicitly
- One clear ask, with a deadline and a route to decline
Why the draft-it-yourself route fails
Start from what the guidance asks a letter to do:
"Submitted letters should specifically describe the person's contribution and its significance to the field and should also set forth the basis of the writer's knowledge and expertise." USCIS Policy Manual, Volume 6, Part F, Chapter 2
The second half is the problem. The basis of the writer's knowledge is something only the writer has. A drafted letter can assert it, but it cannot supply the specific texture that makes it credible: which meeting, which project, what they saw, when.
And the guidance is direct about what generic letters are worth: "Letters that merely reiterate USCIS' definitions relating to this classification or make general and expansive statements regarding the beneficiary and the beneficiary's accomplishments are generally not persuasive."
Letters drafted from a template converge. An officer who reads petitions all day sees five letters in one voice, and the effect is the opposite of the intended one. Recommendation letters and why they cannot carry your case covers the standard in full.
There is also an exposure argument. A service writing letters for recommenders to sign is asking people to attest to words they did not write, which is one of the practices profile-building scams covers, and the consequences of a misrepresentation finding are set out in what a misrepresentation actually costs.
What to send
A good brief is short, specific, and does the writer's homework for them without doing their writing.
One page, not a dossier. Busy people do not read a career summary. Give them the two or three claims you are asking them to speak to.
The specific claims, named. Not "please describe my contributions". Instead: the method you published in 2023 and the fact that their group adopted it; the system you led that their organisation now runs on; the review round they chaired that you served on.
The underlying documents. The paper, the release notes, the deployment record, the citation list. A letter that points at a document is corroborated by it; a letter that floats free is not. The corroboration requirement is the load-bearing part of the guidance: "the statements made by the witnesses should be corroborated by documentary evidence in the record."
A reminder of how they know you. Writers routinely forget to say this, and it is the thing the guidance explicitly asks for. Prompt it: "It would help if you could say how you came to know the work."
What you are not asking for. Say plainly that you are not asking them to assess your eligibility or to use immigration language. That is not their job and it produces the worst sentences in any letter.
What to ask for
Ask for episodes, not adjectives.
A useful request looks like: You chaired the working group in 2022 when we proposed the change. Could you describe what the group was trying to solve, what my proposal was, how the group responded, and what happened afterwards? Anything you can say about how widely it has been taken up would help.
An unhelpful request looks like: Could you write a letter describing my extraordinary ability and my standing in the field?
The first produces a paragraph nobody else could have written. The second produces the letter the guidance describes as merely indicating "that the beneficiary is a competent, respected figure within the field of endeavor" without concrete evidence behind it.
Who to ask
The instinct is to ask the people who like you most. The guidance points the other way:
"The relationship or affiliation between the beneficiary and the witness is also a factor the officer should consider when evaluating the significance of witnesses' statements. It is generally expected that one whose accomplishments have garnered sustained national or international acclaim would have received recognition for their accomplishments well beyond the circle of their personal and professional acquaintances." USCIS Policy Manual, Volume 6, Part F, Chapter 2
That does not make close colleagues useless. A direct supervisor is often the only person who can describe a critical role from the inside, and for employment the regulation actually requires employer letters:
"Evidence relating to qualifying experience or training shall be in the form of letter(s) from current or former employer(s) or trainer(s) and shall include the name, address, and title of the writer, and a specific description of the duties performed by the alien or of the training received." 8 CFR 204.5(g)(1)
The point is the mix. Someone who worked with you closely can describe what you did. Someone who never met you can describe why it mattered to the field, and that second voice is the one most records are short of. How to find and approach that second group is the harder half, and it is the same problem as getting speaking invitations or press coverage without a publicist: it is easier once the work is visible.
Making it easy to say yes, and easy to say no
Give a real deadline, two to three weeks out, and say what happens if they miss it. Nothing happens; you will ask someone else. That is a relief to hear.
Offer a call instead of a letter. Some people will happily talk for fifteen minutes and hate writing. Take notes, send them back your notes, and ask them to write from those in their own words. That is briefing, not drafting.
Say they can decline. A grudging letter reads like a grudging letter.
Do not send a template. If they insist on a starting point, send the questions rather than the sentences.
Say what happens to the letter. People are more careful, and more comfortable, when they know a government officer will read it.
- Two or three specific claims you are asking them to address
- The documents behind each one, attached
- A prompt to state how they know the work
- A note that immigration language is not needed
- A deadline, and permission to decline
- No draft text, and no template sentences
What weight a particular letter carries, and which claims most need a witness, are judgements to make with your attorney against the whole record. Building an EB-1A evidence index is where that mapping lives.

Frequently asked questions
What does USCIS say a letter should contain?
The Policy Manual states that submitted letters should specifically describe the person's contribution and its significance to the field and should also set forth the basis of the writer's knowledge and expertise.
Can I draft the letter for my recommender?
A service or petitioner writing letters for others to sign asks those people to attest to words they did not write. It also produces letters that read alike, and it creates a risk in a federal filing. The better route is to brief the writer properly and let them write.
Should recommenders be people who know me?
Some should, but not all. Guidance notes it is generally expected that one whose accomplishments have garnered sustained national or international acclaim would have received recognition well beyond the circle of their personal and professional acquaintances.
How many letters do I need?
There is no number in the regulation. Letters are corroboration rather than the case itself, so the useful question is which specific claims still need a witness rather than how many letters to collect.
Are letters about employment different?
Yes. The regulation requires that evidence relating to qualifying experience or training be in the form of letters from current or former employers or trainers, including the name, address, and title of the writer and a specific description of the duties performed.
