I'm still convinced that execution is more important than strategy. However, some strategic decisions can make or break your business.
One key decision is choosing the industry you want to enter. Many years ago at Kellogg, I read a statistic that stuck with me: 50% of a business's success depends on the industry you choose.
The next crucial decision is your business plan and positioning. Even though our team at Tukki chose to work in immigration, we could have gone in different directions, like selling software to lawyers or automating the immigration process to replace lawyers. Each option would lead to very different business models, clients, company types, required skills, and economic implications.
I’m asked a lot why we chose to work with lawyers instead of running other business model options. I’ll answer that in this article.
To make a significant impact in the industry, we need to address the biggest pain points, which do not lie with the lawyers, but with the immigrants.
After interviewing dozens of lawyers and immigrants, it became clear that immigrants face the most challenges: inefficient processes, lack of visibility, slow responses, stress, and uncertainty. While lawyers could benefit from better technology, we believed we could make a bigger impact by working directly with immigrants.
Additionally, we think that the pain points that immigrants currently experienced can't be solved by software alone. It requires a combination of software and operations. Great lawyers are part of the operations piece, but bringing in business best practices from other industries makes a huge difference for the immigration experience and ease of process for lawyers.
Involving immigration lawyers from the start is essential to providing the best service to immigrants — we’ve learned this from personal experience. Immigration law is complex and rarely clear-cut. You need the expertise and judgment of an experienced lawyer. While many steps in the process can be automated, there are moments where a lawyer's input is crucial, such as:
Additionally, obtaining a visa or a green card is a life-changing event; immigrants want a team they can rely on, someone to chat with and answer their questions. Our vision of the best immigration experience is the opposite of a self-service, impersonal experience with an AI. We believe in providing a warm, supportive environment with real human interaction.
People often ask, "If you still have lawyers on your team, why should I work with Tukki instead of going directly to a lawyer?"
We combine the best of both worlds: expert knowledge from lawyers and a highly efficient, customer-focused process enabled by our technology.
Neither can deliver the best experience to immigrants alone; you need both.
I admit, this approach didn't come without its challenges! It’s far more complicated to acquire customers, service them, get great lawyers, manage operations end-to-end, and build a great product than just focus on one section of the journey. Scaling is also much easier when you're building a B2B SaaS solution compared to managing operations. That's why, since day one, Tukki has obsessively focused on streamlining operations with technology to become exponentially more efficient and scalable than the status quo.
If you want to truly reinvent an industry, you need to go all in, and that's what we signed up for.

Does an approved I-140 extend L-1A status beyond seven years?
No. Unlike the H-1B, where an approved I-140 enables three-year extensions beyond the six-year cap under AC21, there is no equivalent provision for the L-1A.
The seven-year maximum is a hard limit.
An I-140's value for L-1A holders is that it establishes your priority date and enables you to file I-485 when that date becomes current.
Where can I find my A-Number to renew my green card?
Look at the front of your current green card, where it's labeled "USCIS#," or at the upper-left section of any USCIS approval notice. You'll enter this number when you file to renew your card, a process covered in our guide to renewing your green card.
What is the EB-1A approval rate?
The EB-1A approval rate varies, but well-prepared petitions with strong evidence have a high chance of success. That said, USCIS applies a rigorous two-step review: first checking whether you meet at least 3 criteria, then evaluating the totality of your evidence in a final merits determination.
Working with an experienced immigration attorney can significantly improve your chances. Weak petitions are more likely to receive a Request for Evidence or denial.
Can an EoR file an H-1B for me?
Usually not. The H-1B petitioner has to be the employer with the right to control your work, and an EoR is typically only the legal employer of record for payroll and compliance while your client company directs the job.
Because the controlling employer and the EoR are different entities, the EoR generally fails the petitioner test that USCIS applies.
Can I respond to an O-1A RFE on my own or do I need an attorney?
You can respond on your own if you're comfortable working through the regulatory criteria. Most applicants benefit from at least reviewing a sample response or working with counsel or an immigration service, because the response is your one chance to resolve every concern.
A weak response almost always leads to denial.
