The situation is common enough to be a genre. You reviewed for a conference three years ago, the review system has been decommissioned, the email account was a university one you no longer have, and you did not think to keep anything. What can be recovered, and what has genuinely gone?
- That you were asked, by a named venue, in a named cycle
- That you completed the work, which is the harder half
- What the venue is, and that it is real and selective
- When it happened, precisely enough to place it in your record
- In your field, or an allied one
What the criterion asks for
"Evidence of the alien's participation, either individually or on a panel, as a judge of the work of others in the same or an allied field of specification for which classification is sought;" 8 CFR 204.5(h)(3)(iv)
Note the word: participation. Not invitation, not eligibility, not membership of a reviewer pool. The guidance makes the same point through its examples:
"Peer reviewing for a scholarly journal, as evidenced by a request from the journal to the person to do the review, accompanied by proof that the review was actually completed; Peer review of abstracts or papers submitted for presentation at scholarly conferences in the respective field" USCIS Policy Manual, Volume 6, Part F, Chapter 2
Two artefacts: the request, and proof of completion. The request is usually recoverable. Completion is where reconstruction gets difficult, and knowing that in advance tells you where to spend effort.
Getting judging experience covers the criterion in full, and finding judging opportunities covers the channels.
What is usually recoverable
Work through these in order, because each one is cheaper than the next.
Your own email archive. Search for the venue name rather than for words like "review" or "invitation". If a university account has been closed, ask whether the institution retains archived mail; some do for a period, and the request costs one email.
Public reviewer lists. Many conferences publish an acknowledgements page, a program committee list, or a thank-you to reviewers in the front matter of the proceedings. Proceedings volumes stay online long after the submission system dies. Capture the page with the URL and access date visible.
Editor and chair recognition. Journals publish annual reviewer acknowledgement lists. Some are in the journal itself, some on the publisher's site.
Reviewer profiles. Some publishers maintain verified reviewer records that count reviews completed and let you export a report. If you ever connected an account, the record may exist without you remembering it.
The submission system. Worth trying even when you assume it is gone. Some conference platforms retain historical accounts across years, and a login you have forgotten may still list your assignments.
A letter from the venue. The chair, editor, or committee member who assigned the work. This is the most reliable route and the one most people go to first; it is better used after the free public evidence has been gathered, so the letter confirms a record rather than being the whole record.
What a reconstructed letter can and cannot do
A letter written now can establish what happened, who assigned it, when, and how many submissions you handled. That is real evidence and it is frequently the best available.
What it cannot do is be contemporaneous. A document created in the ordinary course of the work, at the time of the work, and for a purpose other than the petition carries weight for exactly those reasons. A letter written in response to a request from a petitioner is doing something visibly different, and an officer reads it accordingly.
That is not a reason to skip it. It is a reason to make the letter as specific as a contemporaneous record would have been: named venue, named cycle, dates, number of submissions, the nature of the selection, and how the writer knows. A letter that says the person "served as a valued reviewer" adds almost nothing. A letter that says they were assigned six submissions for the 2021 cycle, returned all six by the deadline, and were invited back the following year is doing the work.
Recommendation letters covers the general problem, and most of it applies here.
The framework for missing records
There is a general provision on what to do when required evidence cannot be obtained. It is written around civil documents rather than around criterion evidence, so it is context rather than a rule that governs this situation directly, but the sequence it describes is worth knowing:
"The non-existence or other unavailability of required evidence creates a presumption of ineligibility. If a required document, such as a birth or marriage certificate, does not exist or cannot be obtained, an applicant or petitioner must demonstrate this and submit secondary evidence, such as church or school records, pertinent to the facts at issue. If secondary evidence also does not exist or cannot be obtained, the applicant or petitioner must demonstrate the unavailability of both the required document and relevant secondary evidence, and submit two or more affidavits, sworn to or affirmed by persons who are not parties to the petition who have direct personal knowledge of the event and circumstances." 8 CFR 103.2(b)(2)(i)
Two things transfer usefully. Unavailability has to be demonstrated rather than asserted, and the burden climbs as the evidence gets further from the original. Whether and how this provision applies to a criterion exhibit is a legal question for your attorney, and it is worth asking rather than assuming.
When to leave it out
A judging claim resting on a single unverifiable assertion is not free. It occupies space, it invites a question, and if the question goes badly it colours how the rest of the record reads.
If a seat cannot be documented beyond your own recollection, the honest options are to document it as far as it goes and present it as one part of a criterion that stands on other seats, or to leave it out and build the criterion on assignments you can evidence. Which criteria to build first covers that triage, and the general principle that a criterion argued on thin facts may not survive is the lesson of Kazarian.
Doing it properly next time
Everything above exists because a five-minute habit was skipped. The habit:
- Save the invitation email as a PDF, with headers, not as a screenshot
- Save the confirmation that the review was submitted
- Screenshot your assignment list, with the venue and cycle visible
- Screenshot the public reviewer or committee page, with URL and date
- Note the numbers: submissions assigned, submissions completed, deadline met
- File it somewhere permanent, not in an employer or university account
The last one is the failure that recurs most. Evidence stored in an account somebody else controls is evidence with an expiry date you do not set. Building an EB-1A evidence index covers where it should live instead.

Frequently asked questions
What does the judging criterion require?
Evidence of the alien's participation, either individually or on a panel, as a judge of the work of others in the same or an allied field of specification for which classification is sought.
What proof does USCIS describe for peer review?
The Policy Manual gives peer reviewing for a scholarly journal as an example, evidenced by a request from the journal to the person to do the review, accompanied by proof that the review was actually completed.
Can I use a letter instead of the original records?
A letter from the venue confirming what you did is legitimate evidence and is frequently the best available. It is weaker than contemporaneous records because it is written for the petition rather than created in the ordinary course, and an officer can see that.
What does the regulation say about missing documents?
8 CFR 103.2(b)(2)(i) provides that the non-existence or other unavailability of required evidence creates a presumption of ineligibility, and sets out a sequence of secondary evidence and then affidavits. It is written around required documents such as civil records rather than around criterion evidence.
Is an invitation enough on its own?
The guidance describes the request together with proof the review was completed. An invitation shows you were asked, not that you judged anything.
