1) Get a job offer from a friend or connection who runs a US business... or... 2) Offer your services at a significant discount to a local worker. Work visa is the fastest, easiest way. Still not easy, but better than marrying someone for a visa.

I am a bit confused why you are starting a business, but asking how to best monetize it. That is a red flag, at the start. In my experience, when you are starting (or looking to gain more clients), defining a niche is a far better strategy than being a generalist. That said, once you are established, you can expand your service offerings. But at the start, you must be known for something (a niche), otherwise, you’ll be known for nothing. By choosing a niche, you can position yourself as a true expert and give your clients the assurance that you understand their needs, speak their language, and know how to solve their problems. As a generalist, you are likely to be seen as a “Me too!” A widget who can be replaced at any time. Further, a widget often relies on competing on price, as there is no differentiator between you and the next widget. You are interchangeable. Therefore, you must be cheaper than the next widget and a race to the bottom ensues. And be careful, because a race to the bottom is not one you want to win.

Let's first of all position who are the audiences for an Immigration Firm. If we classified immigration into: 1- Skilled immigration (Employees), and 2- Business Immigration (Investors) Skilled Immigration fees are affordable and due to the high competition the Professional Fees are competitive and payment plans are there to attract more clients. HINT: Despite that, Applicants have to conduct an overall check up about the credibility of their meant immigration consultants. On the other hand, Business Immigration which involves a bigger amounts of fees and investment are treated somehow different. As per the country of destination and the route of immigration which is almost limited between Property Investment, Financial Instruments Investment and Donation varieties of payments plans are offered to attract Investors. In other words, Legal Fees and Processing Fees are considered as a small portion of the Deal which doesn't shape a concern to Migrant Investors rather than the tool used for immigration and the success rate of that firm. HINT: When choosing an immigration program it is preferable not to pick Immigration firms relying only on RCBI programs (Residency & Citizenship by Investment) as the risk lies in the project continuity as per the demand which to some extent can delay the whole immigration files under that project.
