Startup Job Boards and Visa Sponsorship: What Wellfound and YC's Work at a Startup Can and Can't Tell You

Wellfound and YC job pages both carry a visa label, but it answers a narrower question than you think, so here is how to read it before you apply.

Wellfound visa sponsorship information sits on each job page, not in a search filter we could find. Every Wellfound listing we opened on November 2, 2026 carried a "Visa Sponsorship" field (all five read "Not Available"), while the public search offered only job-title and location boxes. YC's job pages, which you apply to through Work at a Startup, carry a "Visa" field with three values: "Will sponsor," "US citizen/visa only" and "US citizenship/visa not required." Both are labels the employer sets. Neither is a promise, and neither tells you whether a startup can support STEM OPT or will actually file an H-1B.

Status as of 2026-11-01. The $100,000 H-1B payment is not being collected: courts vacated the agency policies that carry it out, while Proclamation 11069 stays in effect on paper to 2027-09-21. It never covered a change of status USCIS grants inside the US. A $103,265 fee on certain cap-subject petitions is proposed only (NPRM; comments closed 2026-09-24). FY2028 H-1B registration is not announced. The H-1B worker 60-day grace period, which matters if a startup folds, still applies; ending it is proposed (RIN 1615-AD22; comments close 2026-11-10).

Our stake: F1Jobs sells a job-search service to visa holders. This guide sticks to what the boards display and what government tools show.

Wellfound visa sponsorship: what the label shows and where

On Wellfound, sponsorship appears as a "Visa Sponsorship" line on each job page, beside salary, equity, location, remote policy and relocation. The employer fills it in when it posts the role. It states the company's intent for that one role, not its filing history, its E-Verify enrollment or whether it can pay an H-1B wage.

What we saw on Wellfound's public job search on 2026-11-02, signed out:

• Search. Two boxes, "Job title" and "Location." No visa control was visible. A sign-up pitch promises a way to "Filter by industry, job title, location & more," but we could not see the signed-in filters. Any visa filter there could only sort on the same employer-set label.
• Job pages. "Visa Sponsorship," "Relocation," location, remote policy, salary and equity. All five we opened read "Not Available" and "Not Allowed," a tiny sample rather than a rate.
• Company cards. Size bands ("1-10 employees," "11-50" and up) and stage tags such as "Early Stage" and "Growth Stage."

Read the description too. Some postings require existing US work authorization, and some defense or aerospace roles are limited to "U.S. persons" under export-control (ITAR) rules, a group that excludes F-1 and H-1B holders. No sponsorship fixes that, so skip those roles early.

Your profile gets filtered as well. Wellfound's help center tells recruiters they can require "Authorized to work in the U.S." and screen out candidates who "have indicated that they require visa sponsorship." Answer those questions accurately; a company that filters on them has told you something useful about fit.

What "Not Available" means if you are on OPT

For startup jobs for OPT students, this label matters most. Your OPT EAD is current work authorization, so some "Not Available" employers will still hire you; they just do not plan to file an H-1B later. That can be a sensible bridge job if you know your clock: 90 days of unemployment on post-completion OPT, 150 in total with STEM OPT, per the SEVIS Help Hub. A STEM extension there still requires the employer to meet the rules below.

What YC's "Visa" field means on Work at a Startup

YC lists startup roles on ycombinator.com/jobs, with each company's batch beside its name (for example "W22"), and you apply through a YC account on Work at a Startup ("Apply to thousands of startup jobs with a single profile"). We saw no visa filter on the public page and could not see the signed-in search. Work at a Startup visa sponsorship information lives in the "Visa" line in each job header.

YC job "Visa" labels, as seen on 2026-11-02

The middle label trips people up. YC's own Product Engineer listing showed "US citizen/visa only" in its header, while its body said: "Employer is willing to sponsor certain employment visas in accordance with company policy." Header and body disagreed in your favor, so read the whole posting before ruling a role out.

Do YC startups sponsor H-1B?

Some do, many do not: YC startups' visa sponsorship is decided company by company, and the batch badge tells you nothing either way. YC is an investor; each company is a separate employer that files its own petitions under its own legal name. A W22 badge means YC funded the company, not that it has ever filed an H-1B.

Silence is the norm across tech hiring. According to a single vendor, Match.dev, which read 2,718 US software roles at 136 companies on 2026-10-13, 88.1% of postings said nothing about sponsorship, 10.0% said it was possible but not promised, 0.4% explicitly offered it and 1.1% refused it, while 90.7% of application forms asked about work authorization (Match.dev data). A board that labels every role tells you more than most. If you are building a list of startups that sponsor H-1B, the label is where you start and the filing record is where you confirm. Our guide to H-1B-friendly job boards beyond LinkedIn covers other places to look.

Can an early-stage startup sponsor an H-1B?

Yes. No rule sets a minimum company size. The startup needs a specialty-occupation role, a certified Labor Condition Application (Form ETA-9035) from DOL, an I-129 petition to USCIS and, for most new hires, a lottery selection first.

The binding money question is wages, not fees. DOL's H-1B program page says employers attest they will pay at least "the actual wage paid by the employer to other workers with similar experience and qualifications" or "the prevailing wage for the occupation in the area of intended employment," whichever is greater. A seed-stage company that pays mostly in equity still needs a cash salary above that line. DOL's plan to raise prevailing-wage levels is still proposed (RIN 1205-AC30, no final rule), so today's levels apply.

Salary also changes lottery odds. Wage-weighted selection has been in effect since 2026-02-27: a registration at wage Level IV gets four entries and Level I gets one (final rule; USCIS registration page). Ask the company's attorney where your salary lands. For the wider comparison, see startup vs big tech H-1B sponsorship tradeoffs.

The myth that startups can't afford the $100,000 fee

As of 2026-11-01 the payment is not being collected. Courts vacated the agency policies that implement it (California v. Mullin, Global Nurse Force v. Trump), and both cases are on appeal. USCIS's H-1B page (updated 2026-09-21) says the proclamation does not apply to a petition "requesting an amendment, change of status, or extension of stay for an alien inside the United States," the usual OPT-to-H-1B path when USCIS grants it. The catch, on the I-129 page: "If this order is later lifted, DHS still plans to collect the payment." A denied change of status or a consular-notification petition would be covered then.

USCIS costs of an H-1B for a startup employer, as of 2026-11 (G-1055 edition 10/26/26)

Check the live G-1055 fee schedule before anyone pays; it still prints a $100,000 line, which is not evidence of collection. Attorney fees are separate. A young startup with few visa holders would not meet both 9-11 fee tests (our reading).

Do startups use E-Verify for STEM OPT?

Only the ones that want to employ you on the STEM OPT extension must. Post-completion OPT has no E-Verify requirement, but the 24-month STEM extension does, and a young startup may never have enrolled. Ask before you accept, not in the week your OPT ends.

USCIS's STEM OPT page says the employer must "Be enrolled in E-Verify" (or hold "a valid E-Verify client company identification number" if an employer agent runs its cases), have an EIN, sign a Form I-983, implement "a formal training program," offer duties and pay "commensurate with those of similarly situated U.S. workers," and have a bona fide employer-employee relationship with you. Some arrangements, "including multiple employer arrangements, sole proprietorships," may fail that last test.

• Payroll providers. Running payroll through a provider or PEO does not settle E-Verify by itself; USCIS asks for the startup's own company ID or a client company ID under an agent. Our guide to getting an employer to enroll in E-Verify for STEM OPT covers the ask.
• Checking it yourself. The E-Verify Employer Search updates "daily at approximately 2 a.m. ET," finds a brand name only if the employer gave that DBA at enrollment, and does not confirm every hiring site. A missing startup may be listed under its legal name.

Timing: E-Verify's authority runs with the continuing resolution through 2026-12-11 and lapses after that unless Congress passes funding by 2026-12-11; in the 2025 shutdown it was offline from 2025-10-01 to about 2025-10-08. For a December STEM OPT start, ask the employer to enroll early.

How to vet a startup you found on a board

The label gets a startup onto your list; these steps decide whether it stays. For the deeper single-company check, use our checklist for whether a startup can sponsor your H-1B.

1. Screenshot the Wellfound or YC visa label with the date. Labels change when roles are edited.
2. Find the company's legal entity name, often different from the brand (check offer letters and terms-of-service pages).
3. Search that name in the USCIS H-1B Employer Data Hub, which now says it covers fiscal years 2009 through 2026 (quarter 4). Look at initial approvals, not only continuing ones.
4. Search the DOL OFLC LCA disclosure files, latest release through 2026-06-30, for titles, wage levels and worksites. See how to search LCA filings.
5. Look up the prevailing wage for your occupation and county on DOL's OFLC Wage Search and compare it with the listed cash salary.
6. Check the E-Verify Employer Search if you will need STEM OPT.
7. Ask the founder the questions below, in writing.
8. Take STEM OPT and Form I-983 questions to your DSO, and H-1B strategy to an immigration attorney. The company's counsel represents the company, not you.

A brand-new startup will have no Data Hub or LCA record. That is not disqualifying, but it moves the weight onto steps 5 through 8.

How do I ask a startup founder about sponsorship?

Ask early, in writing, and specifically. At an early startup the person who answers is often the person who decides, so raise status in the first real conversation, not after the final round.

I'm on F-1 OPT, authorized to work through June 30, 2027, and my degree is on the STEM list, so I plan to apply for the 24-month STEM OPT extension. I'd need H-1B sponsorship to stay longer. Have you filed an H-1B before, do you work with immigration counsel, and are you enrolled in E-Verify or willing to enroll for a STEM OPT hire?

Strong answers name a law firm, describe a past filing or a plan to register you, and treat the I-983 as normal paperwork. "We'll figure it out" is weak. Neither proves anything, so get the commitment repeated in the offer process. For outreach before any conversation, see getting a visa-sponsoring startup to notice you.

A worked timeline: OPT now, startup offer, FY2028 lottery

Say your post-completion OPT ends 2027-06-30 and you find a Series A startup whose listing says it sponsors.

Example timeline, as of 2026-11 (dates are expectations unless marked)

If you are not selected, STEM OPT buys another lottery attempt, and only an E-Verify-enrolled employer can provide it. Cap-exempt petitions get no cap-gap; your own I-20, EAD and notices govern.

Common mistakes

• Treating "Will sponsor" as a commitment. It is a label, and it may not even mean a US visa.
• Reading "Not Available" as "won't hire me on OPT." The label is about sponsorship later.
• Reading "US citizenship/visa not required" as sponsorship. In our snapshot it marked roles abroad or remote ones.
• Searching the brand name. The Data Hub, LCA files and E-Verify search list the name the employer filed or enrolled under.
• Believing the $100,000 payment rules out startups. As of 2026-11-01 it is not collected, and it never covered in-US changes of status USCIS grants.
• Waiting until the offer to mention status. On a 90-day OPT unemployment clock, a late "no" costs weeks.

Frequently asked questions

Does Wellfound have a visa sponsorship filter?

Not one we could confirm. On November 2, 2026, Wellfound's public search offered only job title and location boxes, but every job page we opened carried a "Visa Sponsorship" field, and all five read "Not Available." Treat it as the employer's own label for that role, then confirm it with filing history and a direct question.

Do YC startups sponsor H-1B?

Some do and many do not, because each YC company is a separate employer. YC job pages show "Will sponsor," "US citizen/visa only" or "US citizenship/visa not required," and the header can understate the details further down. Check the company in the USCIS H-1B Employer Data Hub and the DOL LCA files.

Can an early-stage startup sponsor an H-1B?

Yes. Size is not a legal bar, but the startup needs a qualifying role, a certified LCA and the cash to pay at least the higher of its actual wage or the prevailing wage. As of 2026-11-01 the $100,000 payment is not being collected and never covered changes of status that USCIS grants inside the US.

Do startups use E-Verify for STEM OPT?

Only those employing you on the STEM OPT extension must. USCIS requires E-Verify enrollment, an EIN and a signed Form I-983, while regular post-completion OPT has no E-Verify requirement. Many young startups have never enrolled, so ask early and check the E-Verify Employer Search.

How do I ask a startup founder about sponsorship?

Ask early, in writing, and specifically. State what you have now and what you will need later, then ask about past H-1B filings, immigration counsel and E-Verify. A founder's yes is a starting point, so get it confirmed in the offer process.
