Thanks to the EB-5 Reform and Integrity Act that was passed in March of 2022, there has never been a better time to switch from an H1-B visa to an EB-5 green card. The Act allows for concurrent filing, which allows an H-1B visa holder to file an I-485 adjustment of status at the same time they file their I-526E EB-5 investor petition.
This allows the investor, as long as there is a visa available for their nationality, to obtain the benefits of an EB-5 conditional green card as soon as the adjustment of status is approved by USCIS (typically 8-10 months).
There are several advantages to being on an EB-5 conditional green card as opposed to an H1-B visa.
They include:

No Work Restrictions

A person who transitions from an H1-B visa to an EB-5 green card gains the freedom to work without limitations. With a conditional green card, there's no need for a work sponsor, and they’re free to choose any job—even outside their degree field—without needing to prove that no U.S. worker is qualified. Unlike an H1 visa holder, a green card holder can also start their own business.

Other Family Members Can Work

With an H1-B visa, only the sponsored individual can legally work. But after moving from H1 B visa to green card status through the EB-5 program, all family members of legal working age can seek employment in the U.S.

Better Pay

Switching from an H1 visa to green card allows professionals more freedom in the job market. H1-B visa holders are often tied to one employer and have limited ability to negotiate pay. In contrast, a conditional green card holder—thanks to the EB-5 visa path—is not bound to a single employer and can negotiate better salaries.

Fewer Travel Restrictions

Compared to H1-B visa holders, who often need extra documentation for international travel, those who have gone from H1 B visa to green card can travel more freely. Green card holders can apply for a U.S. passport and avoid many of the limitations that come with an H1-B visa.
