As Co-founder of Domu, a fintech startup innovator in Brazil, Camila Zancanella is no stranger to navigating complexity—at least when it comes to growing a company. But the US immigration system presented a different kind of challenge.
For Camila, the opportunity arose to expand her company’s presence in the US, and securing an O-1 visa became her top priority. Navigating the complex immigration process was simplified thanks to the innovative platform and dedicated team she discovered through a previous visa petitioner.
As a startup founder, Camila is adept at managing high-pressure situations, but the intricacies of the US immigration process presented unique challenges. The O-1A visa required extensive documentation, including letters from experts and proof of her extraordinary achievements.
Her decision to partner with Tukki came after a trusted referral, and the choice was solidified after her first meeting with the team. “From the first meeting, I felt a connection,” says Camila. “Tukki’s team understood my needs and made the process feel approachable and well-organized.”
In an interview with our team, Camila shared the reasons she chose Tukki to manage her O-1A visa process.
Empathetic support: Camila valued the consistent care and responsiveness of Tukki’s team.
“Whenever I felt lost, someone was always there to help me out—sometimes responding within minutes. That kind of support made all the difference.”
Streamlined process: Tukki’s platform simplified the application process by providing clear steps and real-time feedback.
“I didn’t even see the time pass. The platform made it clear what I needed to do next, and I didn’t have to figure everything out on my own.”
Stress-free feedback: Quick feedback and transparency helped Camila stay organized and focused.
“When I submitted something, I’d get quick feedback—whether it was approved or needed improvement. That organization saved me so much time.”
The O-1A visa requires applicants to demonstrate extraordinary ability in their field. For Camila, that meant documenting Domu’s fintech impact and her leadership achievements. For this, “the platform was a game changer,” affirms Camila. “Everything I needed—documents, timelines, feedback—was organized in one place. It was simple to track progress and know what came next.”
“Immigration processes can be so stressful, but Tukki really cared about me and my experience. They were there for me at every turn, making sure I felt supported.”
The combination of cutting-edge technology and compassionate service was what stood out for Camila, which is no surprise to Tukki’s team since fast responses and an efficient platform were huge parts of the product design process. Visa applications can be smooth and should feel like an empowering experience.
With her O-1A visa approved, Camila is now settled in San Francisco with her husband and their beloved husky. She’s excited to expand Domu’s US client base and foster relationships within the fintech ecosystem. “Being closer to our US clients will make a huge difference for Domu. The relationships we build in person will take our service to the next level.”
In fact, Camila’s positive experience with Tukki has inspired her to bring the platform to her team as they navigate their own immigration processes: “Tukki made such a difference for me. I’m confident they’ll do the same for my team.”
Whether you’re a visionary founder like Camila or a professional seeking new opportunities, Tukki ensures you have the support you need to succeed.

How long does it take to get an O-1B visa for musicians?
Regular processing times vary and can take several months depending on USCIS workload. Premium processing costs $2,965 as of March 1, 2026, and guarantees an initial response within 15 business days.
Keep in mind that the advisory opinion letter from a union or peer group (such as the AFM) adds time to the preparation phase, so plan to start that process well before your target filing date.
What's the difference between O-1A and O-1B for content creators?
The O-1A covers extraordinary ability in business, science, education, or athletics, while the O-1B covers extraordinary achievement in the arts.
If your content creation is primarily creative, such as video production, photography, or music, the O-1B is likely the right fit. If you've built a business around content creation, like launching a product line, running an agency, or scaling a media company, the O-1A may be stronger.
The classification depends on the nature of the work you'll perform in the U.S.
Is the O-1 visa easier to get than the H-1B?
Not on the eligibility side. The H-1B is harder to win because of the lottery, but the underlying criteria are more accessible: a bachelor's degree, a specialty occupation job, and a willing U.S. employer.
The O-1 has no lottery, but the evidence requirements for extraordinary ability are real and selective, so the bar is higher even though the process is more flexible.
What is the O-1A visa approval rate?
The O-1A visa approval rate is around 90% for petitions that make it through initial adjudication. That said, this number reflects cases that were filed with professional preparation and strong evidence.
Weak petitions are more likely to receive a Request for Evidence or be denied. Working with an experienced immigration attorney can significantly improve your chances.
How many reference letters do I need for an O-1A?
Most strong O-1A petitions include 6 to 10 letters. The exact count matters less than the mix: aim for 3-4 independent experts, 2-3 senior leaders or supervisors, and 1-2 close collaborators.
A package of 6 well-targeted letters consistently outperforms 12 generic ones.
