No bureaucratic process is known for being easy or enjoyable, but understanding the steps that await us, how to approach them, and who to have by our side helps streamline the process.
Clarity and transparency are crucial for the beneficiary (i.e. the immigrant) as much as their legal team, but to date, no one tool or team has been able to provide this. That’s why we created Tukki — to combine the best of technology with lawyers — as well as this guide. There’s no reason why a comprehensive overview to assist you in making informed decisions should be hard to access.
Here, our focus will be on the most common nonimmigrant visa types that suit business owners and entrepreneurs primarily, so you can make sensible decisions about your future and your visa.
The E-2 visa is for investors, executives, and managers from treaty countries who invest significant capital in a U.S. enterprise. The L-1A visa is for managerial or executive employees being transferred to the U.S. from an international organization. The O-1A visa is for individuals with extraordinary ability in their field.
To overly simplify: the E-2 focuses on the investment, the L-1A on the company and the immigrant’s role within it, and the O-1A on the individual and their accomplishments.
The E-2 visa caters to investors from treaty countries who invest significant capital in a US. enterprise.

In short, the E-2 visa is ideal for investors from treaty countries making substantial investments in US. businesses. The L-1A visa is suited for managerial or executive employees of multinational companies being transferred to the US. The O-1A visa caters to individuals with extraordinary abilities in various fields.
Each nonimmigrant US visa category offers unique benefits and challenges—choose the visa route that best aligns with your professional background and business objectives. By thoroughly understanding these nonimmigrant US visas, you can make an informed decision, facilitating your journey to work and thrive in the US. To continue the discovery journey, why not complete an assessment that will point you to your best US visa options?

Find quick answers to frequent visa questions from our legal experts
Can I switch from an E-2 visa to an L-1A visa?
Yes, but you'll need to meet all the L-1A visa requirements independently.
That means you'd need a qualifying multinational employer, at least one year of qualifying employment abroad in a managerial or executive role within the past three years, and a U.S. entity with a qualifying relationship to the foreign employer.
Simply holding an E-2 doesn't give you any advantage in the L-1A petition process.
How many reference letters do I need for an EB-1A petition?
Most strong EB-1A petitions include 6-10 letters, with a mix of 3-4 independent expert letters and 2-4 collaborator letters. The exact number matters less than the balance.
Five sharp letters with strong field-wide impact paragraphs beat ten generic ones, and packages made entirely of co-author or supervisor letters often draw an RFE on the independence question.
Can I register an LLC while on an H-1B visa?
Yes, you can form a legal entity like an LLC or corporation while on H-1B status. Forming a company is a passive activity, and there's no immigration rule against it.
But forming the entity and working for it are two different things. You can't perform work for your LLC unless it sponsors your H-1B and the employer-employee relationship requirements are met.
Can CBP deny entry even if you have a valid U.S. visa?
Yes. A U.S. visa gives you permission to travel to a port of entry and request admission, but the CBP officer makes the final decision. Officers can deny entry for reasons including misrepresentation, prior immigration violations, criminal history, or insufficient documentation.
If you're denied, ask about voluntary withdrawal of your application instead of expedited removal — withdrawal doesn't create a formal removal order on your record.
