For Y Combinator Founders

The batch starts in weeks. The visa plan starts now.

Y Combinator runs four batches a year, invests $500,000 in each company, and expects founders in San Francisco. For an international founder, the acceptance email starts a clock that most U.S. work visas cannot beat: the program begins in weeks, and petitions take months. The founders who handle this well do not hunt for one perfect visa. They run a sequence.

The sequence is usually a visitor entry for the batch, an O-1A petition built on the record the batch creates, and a green card filed once the company can carry it. We build these cases regularly, including for many YC founders, and we will tell you plainly which path fits you and which does not.

The shape of the problem

Three months in San Francisco, on a timeline no single visa was built for.

YC is an in-person program. It opens with a retreat, runs on sessions in San Francisco, and ends at Demo Day in front of investors. None of that waits for a petition to be adjudicated, and an O-1A filed the day you are accepted would still be a rushed O-1A. The good news is that immigration law separates cleanly into what a visitor may do and what a worker may do, and a YC batch sits almost entirely on the visitor side of that line.

So the plan is staged. You attend the batch as a business visitor. You use the batch to generate the evidence a work petition needs, because a launch, a round, and press coverage are exactly what USCIS reads. Then you file the work case, usually an O-1A with premium processing, and you start the green card once the company can support it.

Phase	Status	What happens
The batch, roughly weeks one through twelve	B-1 or ESTA	Program sessions, investor meetings, negotiations, incorporation, Demo Day. No productive work, no U.S. payroll.
Building the company	O-1A	Filed on the batch record, often as a change of status, usually with premium processing. E-2 or entrepreneur parole where they fit better. Work authorization for your company.
Staying for good	EB-1A or NIW	Built from the same record and filed early, because country-of-birth backlogs reward early priority dates.

Every founder's version of this table is a little different: passport, prior record, cap table, and family all move the answer. The sections below walk each phase, and the mistakes section at the end covers the ways the sequence goes wrong.

Phase one

A visitor entry that gets you to Demo Day without breaking anything.

Most founders attend their batch as business visitors, either on a B-1 visa or, for citizens of Visa Waiver Program countries, on ESTA. A business visitor may attend meetings and program sessions, negotiate contracts, raise money, open a bank account, sign a lease, incorporate a Delaware company, and present at Demo Day. What a business visitor may not do is work: productive labor for the company from inside the United States, or salary from a U.S. source.

The two entries are not interchangeable. ESTA is ninety days, cannot be extended, and cannot be converted into another status from inside the country. A B-1 admission typically runs up to six months and leaves room to file a change of status, which is exactly the room an O-1A needs. If you have the choice, the B-1 is usually the better instrument, and what you say at the port of entry matters as much as what is in your passport.

The line is enforced at the border, not just at USCIS. Founders get refused at the port of entry over a one-way ticket and an improvised sentence about moving to San Francisco to build. Preparation is not spin; it is knowing what the classification covers, carrying evidence of your ties and your plan, and answering questions accurately about a trip the law actually permits.

Phase two, for most founders

O-1A: built for people with a record. A YC batch builds one.

The O-1A is the nonimmigrant classification for extraordinary ability in business, science, and technology. It has no annual cap and no lottery, it is decided on evidence rather than chance, and premium processing gives it a fifteen-business-day adjudication window. An initial approval runs up to three years, with extensions available as long as the work continues. For founders, one fact matters more than any other: since January 8, 2025, the USCIS Policy Manual expressly recognizes that a company the beneficiary owns may file the petition, provided the entity is real and there is genuine oversight of the founder's work, typically a board with actual authority.

Qualifying means documenting at least three of eight regulatory criteria. Y Combinator acceptance alone decides none of them. What it is, in a well-built petition, is high-quality evidence: USCIS guidance recognizes selection into a highly competitive accelerator as support for the membership criterion, and the batch investment, the press, and the round that follow feed several others.

The regulatory test

Eight criteria, three required

Nationally or internationally recognized awards or prizes
Membership in associations that demand outstanding achievement
Published material about you and your work in major media
Judging the work of others in your field

The regulatory test, continued

And the other four

Original contributions of major significance to the field
Authorship of scholarly articles
A critical or essential role for organizations with distinguished reputations
High remuneration relative to others in the field

Evidence, on schedule

The batch is an evidence engine if you run it like one.

Most founders arrive with part of a record already: a strong salary history, a critical role at a prior company, publications, a patent. The batch adds the startup-specific layer, and current USCIS guidance tells officers to credit exactly this kind of proof: venture funding as an indicator of compensation and critical role, customer growth, media presence.

We map your criteria at the start of the batch and give every week a job, so the petition is being assembled while the company is being built, not after.

What we bank during a batch

Launch and funding press with real editorial weight
Judging invitations: pitch competitions, hackathons, panels
The YC investment and the round, documented as funding evidence
Letters from investors and partners who know the work
The critical-role record at your own company as it grows

Change of status or consular filing is a real fork. Filed as a change of status from B-1, the O-1A lets you begin working the day it is approved, without leaving. Filed for consular processing, it ends with a visa interview abroad. Which is right turns on travel plans, timing, and risk tolerance, and it is a decision to make before filing, not after.

Where a treaty helps

E-2: a clean route for treaty nationals, with a cap-table catch.

If you are a citizen of one of the eighty-plus E-2 treaty countries, investor status can carry you through the early years. It requires a substantial investment at risk in a real operating U.S. enterprise, majority ownership by nationals of your treaty country, and a role developing and directing the business. It renews for as long as the enterprise operates and qualifies, and your spouse can work.

The catch is arithmetic. Venture rounds dilute, and the moment treaty-national ownership slips below fifty percent, the enterprise stops qualifying. That is why the E-2 tends to serve YC founders as a bridge rather than a destination: it works well between incorporation and a priced round, then hands off to an O-1A before the term sheet that would break it. India, China, and Brazil are not treaty countries, so many founders never reach this analysis and go straight to the O-1A.

The honest read

H-1B: worth a lottery ticket, not worth the plan.

The H-1B is capped at 85,000 new visas a year, runs on an annual registration each March, and starts work each October. Two changes have made it a weaker plan for founders than it already was. Since February 27, 2026, selection is weighted by wage level: a registration at the highest prevailing-wage level receives four entries in the selection pool, and one at the entry level receives one. Early-stage founder salaries usually sit at the bottom of that scale, which means the worst odds in the pool. And a founder H-1B still has to clear the classification's own requirements: a specialty occupation role, a real employer-employee structure, and a wage the company actually pays.

Then there is the litigation you have read about. The proclamation that attached a $100,000 payment to new H-1B petitions for people outside the United States was vacated by a federal district court on June 8, 2026, and the First Circuit declined to revive it on July 24, 2026. As of August 2026 it is not in effect, and the appeal continues. None of that changes the practical advice: register every March, treat selection as a pleasant surprise, and build the real plan on a category that does not run on chance.

The other self-sponsored route

Funded, but the O-1A file is thin? There is a rule for that.

International Entrepreneur Rule

Up to five years of runway on the strength of the raise.

The International Entrepreneur Rule lets DHS parole a founder into the United States on the strength of qualified U.S. venture backing: at least ten percent ownership, a central operating role, and a qualifying raise. No sponsoring employer, no lottery, no degree requirement. It is a demanding filing with real limits, and for the right founder it is the cleanest path on the board. We wrote a complete guide to it.

Read the IER guide

Up to 2.5 years, renewable once, for a five-year maximum
Work authorization for your startup, automatic
Spouse may apply for open-market work authorization
Up to three founders per company
Parole rather than a status: the exit is planned from day one

The destination

The green card conversation starts on day one, not in year three.

EB-1A

Extraordinary ability, the permanent version

EB-1A reads like the O-1A's criteria with a higher bar: sustained acclaim, demonstrated over time and judged strictly. That is exactly why the O-1A record matters beyond the O-1A. Built deliberately, your nonimmigrant file becomes the first draft of the immigrant one, and the evidence you banked during the batch keeps working for you. EB-1A can be self-petitioned, and for most countries of birth the line is short. For India and China it is not, which argues for filing early rather than waiting for the record to feel finished.

EB-2 NIW

The national interest waiver

The NIW waives the job offer and labor certification for work of substantial merit and national importance, under the Dhanasar framework. Founders qualify on the strength of the venture itself: funding, customers, jobs, the technology. Guidance issued January 15, 2025 raised the documentary bar, favoring objective evidence over expert letters, so the modern NIW is built on records rather than rhetoric. It remains a strong self-petitioned route for founders whose work clears the national-importance line.

Priority dates are the quiet variable. Employment-based queues move by country of birth, and for founders born in India or China the wait is measured in years. The answer is not despair; it is sequencing. File the immigrant petition early, keep the O-1A running underneath it, and let the priority date mature while you build.

Common questions

YC founder visa FAQ

Can I work on my startup during the batch if I entered as a visitor?

You can do the visitor half: sessions, mentorship, fundraising, negotiations, incorporation, Demo Day. You cannot do productive work from inside the United States or take U.S.-source pay until a work status exists. Many founders file the O-1A as a change of status during or right after the batch so the working phase begins the day it is approved. Where the line falls in your specific week is a real legal question; ask it before the week happens, not after.

Does YC acceptance get me an O-1A?

Not by itself. Acceptance into a highly selective accelerator is useful evidence, and USCIS guidance recognizes that it can support the membership criterion. The petition still has to document three of the eight criteria with proof an officer can hold. The batch itself, run deliberately, usually supplies what is missing.

Can my own startup sponsor my O-1A?

Yes. Since January 8, 2025, the USCIS Policy Manual expressly recognizes that a separate legal entity owned by the beneficiary may file the petition. The entity has to be real, and there has to be genuine oversight of your work, which in practice means a board or similar body with actual authority and a documented record showing it. We set this up correctly at incorporation rather than retrofitting it at filing.

How fast can the O-1A actually move?

The adjudication can be fast: premium processing commits USCIS to act within fifteen business days. The build is what takes time, typically some weeks of evidence gathering, letters, and drafting done properly. Founders who start the file at acceptance rather than at Demo Day compress the total timeline dramatically.

I am a citizen of India, China, or Brazil. What changes?

Two things. The E-2 is off the table, because none of the three are treaty countries, so the working-status question usually resolves to the O-1A or entrepreneur parole. And on the immigrant side, the queues for people born in India and China are backlogged, which makes filing early more valuable, with the O-1A carrying you while the priority date matures.

Should I still enter the H-1B lottery?

Yes, the way you would buy a raffle ticket. Registration is simple and selection is a nice option to hold. But selection is now weighted by wage level, early-stage founder salaries carry the lowest weight, and a founder petition has structural requirements of its own. Nothing about the H-1B should sit on your critical path.

Can my spouse work?

It depends on your category, and it is worth choosing with that in mind. O-3 dependents of O-1 holders may live and study in the United States but may not work. E-2 spouses may work incident to status. The spouse of a founder on entrepreneur parole may apply for open-market work authorization after being paroled in. If your spouse's career is a hard constraint, say so at the strategy stage. It changes the recommendation.

What about the International Entrepreneur Rule?

It is the other self-sponsored route: parole for up to five years on the strength of qualified U.S. venture backing, with no lottery and no sponsoring employer. It is demanding on evidence, and it is parole rather than a status, which constrains what it can become later. We wrote a complete guide, linked above, and in the right case we recommend it without hesitation.

When should the green card work start?

In the first conversation. The EB-1A grows out of the same record as the O-1A, and the NIW rewards the objective evidence a funded startup produces. Backlogs by country of birth make early priority dates valuable. The green card is not a later project; it is the destination the whole sequence points at.
