Unfortunately, as long as you are under that H1B visa, the only company entity that you can be involved with (except for your employer) is still going to be a C Corp.
Please see below:
The following is from
I have an current and valid H1B visa. Can I start my own US company ?
"If one is in H1B visa status and they wish to start and work for their own company a new H1B petition must be filed. The USCIS issued a memorandum back in January 2010 in which USCIS takes the approach that in such a case, when one self-petitions, the H1B application may not be successful because the petition may not be able to establish that the requisite employer / employee relationship exists. For immigration purposes, the employer / employee relationship must be present and this often may be difficult to establish in a closely-held, corporate entity. Other legal issues, as well as many practical business matters, may create obstacles, as well.
Please note that one may be able to passively invest without filing an H1B petition. Please be sure to consult with a qualified immigration attorney before taking any steps in starting ones own company to ensure that you are not engaged in unauthorized employment. "
The H1B visa is only issued to EMPLOYEES, not for self employment.
The C Corp is one of the few entities (entities being Sole Proprietor, Partnership, S Corp) that is NOT a "pass through" entity, Meaning you can leave the earnings in the company, as opposed to having all of the gains/losses passed directly to you every year on the above named entities.
I know that this is still not the answer you were hoping for, and if there was any legal way to answer it any differently, it would have been my pleasure to do so.
