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.

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?

How does USCIS evaluate the EB-1A eligibility criteria?
USCIS evaluates EB-1A petitions using a two-step process.
First, you must either demonstrate a major internationally recognized award or meet at least three of the ten regulatory criteria. While three is the minimum, satisfying more criteria generally strengthens your case.
Second, USCIS conducts a final merits review, assessing the overall quality, significance, and impact of the evidence compared to others in your field.
How much are EB-5 attorney fees?
There's no single market rate, because EB-5 legal work is quoted per stage and the source-of-funds documentation drives most of the effort. Expect separate quotes for the investor petition, the green card stage, and the Form I-829 removal of conditions, and ask whether an RFE response is included or billed as additional work.
Tukki's pricing tool returns one end price that already covers the USCIS filing fees and any RFE response, so you can compare it against a per-service quote directly.
What's the difference between the O-1A and H-1B for software engineers?
The H-1B requires a bachelor's degree, ties you to one employer, mandates prevailing wage compliance, and subjects you to an annual lottery with roughly a 25-30% selection rate.
The O-1A has no cap, no lottery, no degree requirement, and no minimum salary. It also allows agent sponsorship, giving you more flexibility.
The trade-off is that the O-1A requires you to prove extraordinary ability through documented evidence, while the H-1B requires only a specialty occupation and qualifying degree.
When can I start working for the second employer?
Under H-1B portability rules, you can begin working as soon as the second employer files a proper petition with USCIS.
However, if USCIS ultimately denies that petition, USCIS would consider your work for that employer unauthorized retroactively.
Some workers prefer to wait for approval to avoid this risk.
What is evidence of approved I-129 status?
When USCIS approves an I-129 petition, they issue Form I-797, Notice of Action.
This approval notice serves as official evidence of the approved I-129 status.
The beneficiary may use it for visa stamping at a U.S. consulate or to document their authorized stay if already in the United States.
