The 90 day rule in immigration - changing status after you enter on a B-1/B-2
9 mins read | Sep 15, 2026
The most useful O-1 visa checklist is the one you start a year early. By the time a petition is being assembled, the evidence either exists or it doesn't. The records that carry a case are usually the ones created long before anyone mentioned a visa.
Ask most people what evidence they need and they reach for a document their own company wrote describing their project. A tidy one-page summary of the work, produced for the file. That is the easiest document to make and the hardest one to corroborate.
What carries weight is the organic record:
- The pitch deck an investor saw two years ago
- The email thread where another team adopted your method
- The conference program with your name printed in it
- The funding documents
- The code review history
- The press piece a journalist wrote because the work was interesting
All of it existed while you were doing the work, for reasons that had nothing to do with immigration.
This article is the evidence layer. For the eight criteria themselves and who tends to fit them, start with our O-1A visa guide, then come back here for what to keep.

Why organic evidence for an O-1 visa outweighs a document written for the petition
A letter drafted in 2026 about work you did in 2023 is an assertion. The 2023 artifact is what makes the assertion checkable, and that difference is what an adjudicator is reading for.
USCIS does not dismiss letters. Its Policy Manual guidance on O-1 beneficiaries says detailed letters from experts explaining the nature and significance of a contribution are valuable. It adds that they are most valuable alongside corroborating documentation.
The letter supplies the expert judgment. The contemporaneous record supplies the proof that the thing described happened the way it is described.
There's a structural reason this matters. USCIS reads the record in two steps.
- Meeting the threshold. A petition rests either on a major internationally recognized award or, far more often, on at least three of the eight evidentiary criteria.
- Weighing the whole record. USCIS then weighs all the evidence together to decide whether the record as a whole shows extraordinary ability.
Satisfying three criteria does not end the analysis. A case built on parallel assertions with nothing underneath it can clear the first step and still struggle at the second.
Thin corroboration is one of the patterns behind the most common O-1A RFE reasons. A Request for Evidence (RFE) is USCIS asking for exactly the material you could have saved two years earlier.
None of this makes letters optional. They remain part of almost every petition, and our guide to O-1A reference letters covers who to ask and what a strong one contains. The point is what sits beneath them.
An O-1 visa checklist by criterion: what to save, where it lives, who else has a copy
Proving extraordinary ability comes down to what you can put in front of an adjudicator. Work through the table below by asking three questions for each criterion:
- What record proves it?
- Where does that record physically sit?
- Who besides you can produce a copy if you lose access?
The third question is the one nobody asks until it's too late.
| Criterion | What to save | Where it lives | Who else has a copy |
|---|---|---|---|
| Awards and prizes | The announcement, the selection criteria, the size of the applicant pool, the names of the judges | The organizer's website, your inbox, the award certificate | The awarding body's program office, the comms team that announced it, your co-recipients |
| Membership in selective associations | Your admission letter, the criteria in force the year you were admitted, who reviewed you | The association's member portal, your inbox | The association's secretariat, whoever nominated you |
| Published material about you | The full piece with title, author, outlet and date, saved as a PDF and as an archived link | The outlet's site, which redesigns and deletes | The journalist, your employer's comms or PR team, the agency that pitched the story |
| Judging the work of others | The invitation, the assignment, and proof you completed the review | The conference or journal review platform, which closes after the cycle | The program chair, the journal's editorial office, the platform administrator |
| Original contributions of major significance | Design docs, commit and code review history, patent filings, citation counts, adoption and usage numbers, the message where another team picked up your method | Internal repositories and wikis, your patent counsel's file, scholarly citation databases | Co-authors, patent counsel, the team or customer that adopted the work |
| Scholarly articles | The published version, proof of publication, your listed authorship | The publisher's site, preprint servers, your own drive | Co-authors, the journal, your institution's repository |
| Critical or essential role | Org charts, your offer letter and scope, board and pitch decks that name you, launch announcements, output metrics tied to your work | Company drive, your work email, the investor data room | Your manager, investors who received the deck, the board secretary, the client |
| High salary or remuneration | Contracts, offer letters, pay statements, equity grant documents, comparative wage data for your role and city | The payroll portal, which you lose on your last day | Your payroll provider, the recruiter who placed you, your accountant, the cap table administrator |
Two rows deserve extra attention while you still have access. Critical role evidence is the hardest to reconstruct, because org charts get redrawn and launch emails get archived. High salary evidence is the easiest to lose, because payroll systems cut you off the day you leave.
Our breakdown of how to document a leading or critical role goes deeper on what makes that evidence land.

The O-1 visa evidence that quietly disappears
Some of the strongest material in an O-1 file has an expiry date nobody warns you about, and it is almost always tied to access rather than to time.
A former employer's Slack or Teams history goes dark the moment your account is deactivated. It takes with it the threads where your work was debated, praised, and adopted. The same happens to internal wikis, design review tools, and shared drives.
Repositories are worse. A private repo you contributed to for three years can vanish from your view in a single offboarding ticket. The commit history that shows what you built and when goes with it.
Publications move too. Outlets redesign, paywall their archives, or shut down, and a profile that was live when it was published can be a dead link two years later. Save a PDF and an archived snapshot the week the piece runs.
Then there are people. Each of the following is a potential letter, and each one is easier to reach while the working relationship is current:
- A colleague who managed you
- An investor who backed the round
- A professor who supervised the project
Someone who changes companies, retires, or simply forgets the detail of your contribution still writes a letter, just a much thinner one.
The O-1 visa documents to save this week
If you do nothing else, do this. It takes an afternoon and it changes what's available to you a year from now.
- Make one folder and one index. A single cloud folder with subfolders named for the eight criteria, plus a spreadsheet listing each item, its date, its source, and where the original sits.
- Export from every account you might lose. Current and former employers first: email threads about your work, Slack exports if permitted, design docs, performance reviews, launch announcements, org charts.
- Snapshot every mention of you online. Save each article as a PDF with the URL and date visible, and create an archived copy of the page.
- Pull your compensation record. Contracts, offer letters, equity grants, and pay statements from every role, downloaded rather than bookmarked.
- Document judging and review work as you do it. The invitation, the confirmation that you completed it, and a note of what you reviewed.
- Ask for one thing while it's easy. A short email from a manager, investor, or collaborator describing what you did and why it mattered, written now, when the details are fresh, and kept on file for later.
That last step is the cheapest insurance in this entire O-1 visa checklist. A dated email written for a real reason is a contemporaneous record, and it also gives a future letter writer something concrete to work from.
What to do if your O-1 filing is less than twelve months away
Filing sooner than a year from now changes the order of the work rather than the method, so work backwards from what you can still reach.
- Triage by access, not by importance. Anything held by an employer you're about to leave, a platform that's sunsetting, or a person who's moving on comes first.
- Ask early, ask specifically. People write better letters when the request arrives with dates, project names, and metrics attached, and they respond faster when the ask has a deadline with a reason behind it.
- Chase third parties in parallel. Journals, conference organizers, award bodies, and former investors can confirm what you no longer hold, and those requests sit in someone else's queue for weeks.
- Start the consultation early. An O-1 petition requires a written advisory opinion, usually from a peer group, labor organization, or a person with expertise in your field. That request goes out to an outside body and comes back on its schedule.
- Build the case around the evidence you have. Your record is what it is at the moment of filing, and an honest read of it beats a case padded with documents written to fill a gap.
When a criterion doesn't fit your job: comparable evidence
If one of the listed criteria isn't readily applicable to your occupation, the petitioner may submit comparable evidence for that criterion. The rule sits at 8 CFR 214.2(o)(3)(iii)(C), the section of the immigration regulations covering O-1A evidence.
This works criterion by criterion rather than as an all-or-nothing test. A founder with no scholarly articles can offer something comparable in that slot while meeting the other criteria normally.
Two conditions travel with it. The petition has to explain why the criterion doesn't readily apply to your occupation, because USCIS treats a general unsupported assertion as unpersuasive. And you still need at least three criteria satisfied in total, whether by listed evidence, comparable evidence, or a mix.
This is another argument for keeping the organic record. Comparable evidence tends to be the material a job genuinely produces:
- Repository adoption metrics in place of citations
- A term sheet in place of a grant letter
- A product launch in place of a conference proceeding
What the O-1 petition costs and how long the record has to last
What are the government fees on an O-1 petition?
The O-1 is a nonimmigrant visa, so your employer or agent files Form I-129, the Petition for a Nonimmigrant Worker, on your behalf. As of September 2026, the government fees break down like this.
| Fee | Regular petitioner | Small employer | Nonprofit |
|---|---|---|---|
| I-129 filing fee, O petition | $1,055 | $530 | $530 |
| Asylum Program Fee | $600 | $300 | $0 |
Premium processing, requested on Form I-907, carries a $2,965 fee and a guaranteed 15 business day response. Regular processing times move. Check the current figure for your service center on the USCIS case processing times tool rather than relying on a number you read somewhere.
Fees and processing times are current as of September 2026. USCIS updates these periodically, so check the linked official pages for the latest figures.
Our breakdown of O-1 visa cost covers the full budget, including attorney fees.
How long an O-1 visa lasts, and why the record keeps growing
The record has to keep growing after approval because of duration. An O-1 is granted for the time needed to complete the event or activity, up to three years. Extensions come in increments of up to one year each under 8 CFR 214.2(o)(12)(ii).
Every extension is another look at whether the work continues. If a green card is the eventual goal, the evidence compounds. The EB-1A extraordinary ability green card runs on a related but separate standard with its own criteria, so treat them as two cases rather than one.
Read EB-1A compared with O-1A before assuming a file built for one will carry the other.
