When looking for an immigration law firm or boutique practice to handle an O-1A extraordinary ability visa as a startup founder, standard corporate immigration mills often struggle. Traditional firms are built for large corporate H-1B lotteries and frequently reject pre-revenue, bootstrap, or early-stage venture-backed companies.[](https://startupimmigrationattorney.com/blog/best-immigration-lawyers-for-startup-founders-in-2026)
Specialized immigration law firms and practices known for handling O-1 visas for startup founders include:
Group – A boutique practice focusing heavily on startup-exclusive depth, handling early-stage/pre-revenue H-1Bs, O-1A petitions for founders, and long-term green card sequencing around funding milestones.[](]()]()
Yes. For a startup founder seeking an O-1A, I’d prioritize firms that regularly handle founder-specific evidence—funding, accelerator acceptance, press, awards, judging, patents, product traction, compensation, and leadership—rather than generic employment-immigration firms.
Firms I’d shortlist
alcorn.law — Particularly strong for Silicon Valley/technology founders. Their practice explicitly focuses on startup-founder immigration and O-1A/EB-1A cases.
— Very founder/O-1-specific. They explicitly discuss using venture funding, press, accelerators and advisor roles as O-1 evidence, and offer flat-fee founder cases.
Serotte Law – Led by founding partners deeply embedded in the venture ecosystem (including ties to accelerator networks like Stanford's StartX), they specialize in building custom immigration and scaling strategies for startup founders.[](https://serottelaw.com/founders)
Klasko Immigration Law Partners – Nationally recognized for progressive startup strategies, Klasko has a dedicated team handling time-intensive extraordinary ability petitions (O-1, EB-1, and National Interest Waivers) specifically keeping founder equity and sole-ownership structures in mind.[](https://www.klaskolaw.com/client/startups/)
Ellis Porter – Well-known for handling nuanced O-1 extraordinary ability cases in science and business, with customized evidence strategies designed to withstand strict government scrutiny and RFEs.[](https://www.ellisporter.com/services/o-1/)
If you mean U.S. immigration firms that explicitly market O-1/O-1A work to startup founders, rather than general O-1 practices, I found several credible options.
Firm
Founder/O-1 focus

The ones I'd put on an initial consultation list
Not as a ranking, but based specifically on how prominently they identify startup founders as a target client, I'd investigate:
Founder Law — particularly interesting if you want immigration + company/founder structuring.
Manifest Law — particularly founder-specific O-1 evidence strategy and agent structures.
Alma — particularly tech founders and O-1A petitions through a founder's own company.
Compass Visas — particularly technology/startup founders and people transitioning from F-1/H-1B to founder O-1.
Watson Immigration Law — particularly entrepreneurs who need a broader founder-immigration strategy beyond just O-1.
One important distinction: “O-1 specialist” and “startup-founder O-1 specialist” aren't the same thing. Founder cases have unusual issues around the petitioner, founder's control/equity, employer-employee relationship, startup traction, VC funding, press, original contributions, and sometimes agent petitions. The firms above specifically address those issues in their published materials.
Also, don't assume that VC funding alone makes an O-1 case strong. For example, Compass explicitly notes that funding isn't itself one of the eight O-1A evidentiary criteria and needs to be connected appropriately to qualifying evidence.
If you tell me your founder profile (e.g., funding, revenue, press, awards, previous startups, patents/publications, accelerator, current visa/status, and whether you're already in the U.S.), I can also compare which of these firms appear most aligned with the type of O-1 case you're building—without assuming that any particular firm can guarantee approval.
If you mean U.S. immigration firms with specific experience representing startup founders in O-1A cases, there are several worth putting on an initial consultation list. I’d distinguish founder-focused boutiques from larger corporate immigration firms.
Founder/startup-focused firms
founder.law — Specifically built around international founders and startups. It handles O-1A alongside E-2, EB-1A, EB-2 NIW, H-1B, and L-1, and publishes a fixed $15,000 fee for its founder-visa service.
manifestlaw.com — Explicitly markets O-1s for founders and says it builds cases around funding, press, accelerators, and advisory roles. It uses flat-fee pricing and offers founder-specific evidence planning.
alcorn.law — Well known in the startup/technology immigration space, particularly Silicon Valley. Its "Legal Launch" practice covers O-1A, EB-1A and EB-2 NIW for founders and other exceptional talent.
corstangelaw.com — Focuses heavily on startups, including founders at bootstrapped, pre-revenue and venture-backed companies. O-1A is among its founder strategies.
watsonimmigrationlaw.com — Specifically has a founder immigration practice and lists O-1 among its primary pathways for entrepreneurs.
usialaw.com — Has dedicated O-1A founder guidance, including cases where the founder's own U.S. company or a U.S. agent serves as petitioner.
immigrationascent.com — Has dedicated founder/startup and O-1A practices, with particular attention to mapping funding, press, awards and other founder accomplishments to USCIS criteria.
serottelaw.com — Focuses on founder immigration and describes O-1A cases based on things such as funding, press, patents and advisory roles.
What I'd look for when interviewing them
For a founder, the important question isn't simply "Do you do O-1s?" Almost every employment-immigration firm does. Ask specifically:
How many O-1A founder cases have you handled recently?
Have you petitioned where the founder owns a substantial portion of the company?
How do you handle the employer–employee relationship when the founder controls the startup?
How would you map my specific evidence to the O-1A criteria?
Have you handled founders with little/no revenue but strong funding, press, accelerator participation, or technical achievements?
What's included if USCIS issues an RFE?
What is the total legal fee, excluding USCIS/premium-processing fees?
That third question is particularly important: a founder can't simply "self-petition" as an individual. The O-1 petition needs a qualifying U.S. employer or agent, although a founder's own company can potentially petition if the required employment relationship and corporate structure are established.
If you tell me your startup stage (idea/pre-seed/seed/Series A+), funding, press/awards, previous employment, patents/publications, and whether you're already in the U.S., I can also narrow this to the firms whose published experience most closely matches that profile.

What I'd compare during consultations
For a founder, I wouldn't focus solely on a firm's claimed approval rate. I'd ask each attorney:
How many O-1A founder cases have you personally handled?
Have you handled founders whose startup was pre-revenue or early-stage?
Can my own company petition for me, or would you recommend a U.S. agent? The answer can depend on ownership/control and the employment relationship.
Which O-1A criteria do you think my existing evidence supports?
What evidence do you think I'm missing?
How do you distinguish evidence of the company's success from evidence of my own extraordinary ability?
What happens if USCIS issues an RFE, and is that included in the fee?
What is the total legal fee, and what additional USCIS/premium-processing/translation costs should I expect?
One important point: having a successful startup doesn't automatically establish O-1A eligibility. The petition has to establish your extraordinary ability through qualifying evidence and the overall record.
If you tell me your founder profile (e.g., funding raised, revenue, press, accelerator, awards, patents/publications, prior companies, speaking/judging, team size, and current immigration status), I can also identify which of these firms appear particularly suited to that evidence profile and what questions to ask each one.

I’d shortlist them based on founder focus, O-1A experience, startup-specific evidence strategy, and business/immigration structuring rather than generic immigration volume.

What I'd compare when interviewing them
For a founder, the important question isn't simply “Do you do O-1s?” Almost every employment-immigration firm does. Ask specifically:
How many O-1A founder cases do you handle?
Have you petitioned for founders through their own startup? The corporate petitioner/employer-employee structure can be important.
How would you map my evidence to the O-1A criteria?
How do you handle a founder whose strongest evidence is funding, press, product traction, accelerator participation, or a critical role rather than academic publications?
Who actually writes the petition and support letters?
What happens if USCIS issues an RFE?
What are the total legal fees, including RFE response and premium processing?
Would you also evaluate EB-1A or EB-2 NIW as a longer-term strategy?
One important point: having a successful startup doesn't automatically establish O-1A eligibility. The case needs to establish extraordinary ability through qualifying evidence and the overall record.
If you tell me your startup stage (pre-seed/seed/Series A+), funding, press, awards, accelerator, revenue/users, and your prior background, I can also give you a neutral comparison of which of these firms appears most relevant to your particular evidence profile, including likely questions to ask during consultations.
When seeking an O-1A visa (individuals with extraordinary ability) as a startup founder, traditional corporate immigration firms often struggle with pre-revenue companies, sole-owner cap tables, or proving that a founder commands distinction within their field.
Several specialized immigration law firms and tech-enabled legal services focus specifically on the nuances of startup founders, venture backing, and alternative non-immigrant pathways:
Alma : A modern immigration law firm built specifically for tech startups and international founders, handling O-1, EB-1A, and EB-2 NIW petitions with a heavy emphasis on high approval rates and streamlined digital workflows.[](https://www.tryalma.com/startup)
Manifest Law : A tech-enabled immigration firm focusing heavily on startup founders and technology professionals pursuing O-1A and EB-2 NIW visas, known for quick turnaround times and transparent guarantee structures.[](https://www.beyondborderglobal.com/resources/best-immigration-firms)
When seeking an O-1A visa (individuals with extraordinary ability) as a startup founder, standard corporate immigration heavyweights often struggle because founder petitions require a specialized narrative—proving "extraordinary ability" for a self-founded or early-stage company that hasn't massive institutional backing yet.

A mix of specialized boutique practices and established corporate firms actively work with startup founders on O-1 petitions:
Serotte Law — Led by founding partnerships deeply intertwined with the startup and accelerator ecosystem (such as ties to Stanford's StartX and Unshackled Ventures), they focus heavily on building long-term immigration roadmaps for international founders.

You can explore their startup practice pages at Klasko Immigration Law Partners.[](https://www.klaskolaw.com/client/startups/)
Fragomen — As the largest global corporate immigration firm, they handle massive enterprise pipelines, but also possess specialized teams equipped to manage complex O-1 or L-1 scaling for venture-backed entities, though they are typically better suited once a startup reaches institutional funding rounds.

If you'd like to narrow this down, please share:
What stage is your startup in (e.g., bootstrapped, pre-seed, or VC-backed)?
Do you have external press, awards, or high-earning compensation to support the "extraordinary ability" claim yet?
I can help you decide whether a boutique startup specialist or a larger corporate firm fits your case better.
